    JL Audio CR-1 Active Subwoofer Crossover

    The lucky few who have heard a well-integrated subwoofer in a great audio system know that the subwoofer's effect is profound. While everyone expects the bass extension to improve, most are shocked at the transformation that occurs in the main speakers. They simply open up, delivering improved dynamics, superior imaging and more low-level detail. Many describe it as the greatest speaker upgrade they have ever made.

    Over the years, we have calibrated many subwoofer systems in highly critical listening environments, and we have been frustrated by the limitations of active crossovers we have worked with. Tired of struggling with "blunt instruments", we felt that a higher precision tool was needed, so we decided to build it and call it "CR-1". When properly set up, CR-1 creates a listening experience in which the subwoofers and main speakers become one, delivering a cohesive and compelling sonic presentation.

    The CR-1 Active Subwoofer Crossover has been designed by audiophiles, for audiophiles. We believe it has no equal, offering a powerful combination of subwoofer/satellite tuning features, and a complete commitment to analogue signal purity.

    JL Audio CR-1 Active Subwoofer Crossover


    JL Audio CR-1 Active Subwoofer Crossover

    CR-1 is built around two banks of precision Linkwitz-Riley low-pass and high-pass filters. Multiplying DACs with monolithic ratio matching are employed to adjust the analogue circuit's filter frequencies. This offers superior tracking behaviour and far more precise left/right channel balance, compared to conventional approaches.

    Another of CR-1's unique and powerful features is a pair of rotary controls that control the damping of each filter bank. These damping controls dramatically improve the acoustic summing through the crossover region, by compensating for each speaker system's frequency response. At the center of the front panel, a single intuitive, rotary control permits quick adjustment of the relative level between the subwoofer(s) and main speakers.

    To minimize distortion and noise, CR-1 employs top-grade component parts in its all-analogue audio circuitry: 1% precision resistors, JFET-input audio-grade op-amps, polypropylene film-and-foil capacitors and metallized-polypropylene film capacitors, to name just a few. We also build CR-1 right here in the U.S.A., to ensure top quality and dependability.

    CR-1's input-output design makes it equally adaptable to studio, mastering suite or audiophile two-channel playback environments. To accommodate dual-mode systems, we also include a bypass feature that engages a pass-through from a dedicated "Managed Bass Input" on the rear panel, to the CR-1's subwoofer outputs. This makes it convenient to switch from two-channel to multi-channel mode.

    CR-1 is the ultimate tool for subwoofer integration.

    JL Audio Fathom® v2

    The challenges associated with designing high-output compact subwoofer systems can be quite daunting. In most cases, designers sacrifice low-frequency extension or output capability in order to keep the design small.

    The Fathom® v2 subwoofers sacrifice nothing, thanks to the dynamic advantages of their proprietary JL Audio woofers. These exceptional drivers allow for a true subwoofer passband and very high output, while keeping distortion well below audible thresholds. To extract full benefit from the excursion envelope of its woofer, each Fathom® v2 employs an exceptionally powerful switching amplifier with a large toroidal transformer and a patented circuit designed to enhance control and fidelity.

    The compact design and conventional form factor of the Fathoms apply beautifully to most home theater applications, including built-in designs. Front-mounted controls make them a dream to set up and adjust, while JL Audio’s exclusive Digital Automatic Room Optimization circuit makes sure that response is smooth, even in challenging rooms.

    Simply put, Fathom® v2 is the compact subwoofer system for those who enjoy demanding program material and won’t settle for compromises.

    JL Audio Fathom® v2 Technology -



    Dynamic Motor Analysis - DMA Optimized Motor

    Summary:

    JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modelling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.

    Detailed Information:
    Since 1997, JL Audio has been at the forefront of Finite Element Analysis-based modelling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the "Loudspeaker Genome"... a project aimed at understanding the true behaviour of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.

    DMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, "big-picture" solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behaviour under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modelling routines are intense, requiring hours to run for a whole speaker.

    DMA is able to analyse the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the "fixed" magnetic field. This delivers intensely valuable information compared to traditional modelling, which assumes that the "fixed" field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this "fixed" field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analysing this behaviour is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behaviour:

    1. Linear motor force over the speaker's operational excursion range
    2. Consistent motor force with both positive and negative current through the coil
    3. Consistent motor force at varying applied power levels

    Our ability to fully analyse these aspects of motor behaviour allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.

    The payoff is reduced distortion, improved transient performance and stellar sound quality.

    The Absolute Sound reviews JL Audio's E-112 (1500w) active subwoofer -

    http://www.theabsolutesound.com/arti...112-subwoofer/

    "The qualities that have made previous JL Audio’s subwoofers exceptional—lack of bloat and overhang, coupled with tremendous power and authority—were evident in the new, more affordable e112. The pair of e112s was quick and agile, reproducing transient information with no smearing of leading-edge attacks, plus very fast decays. As a result, the subs didn’t dilute pace and rhythm, as many subs do."

    "The JL Audio e112 seems to have sworn the Hippocratic Oath: First, do no harm. The e112 follows this dictum in two ways. First, its integral crossover is extremely clean and transparent. Second, this sub doesn’t call attention to itself by weighing down the music with a bloated rendering of the bottom end. These qualities alone would make the e112 a standout."

    "It’s this combination of finesse and impact that makes the e112 such a stand-out in a crowded field—and at an eminently affordable price."


    JL Audio's E-112 1500w active subwoofer is at Musicraft (Derby)

    The E-Sub powered subwoofers apply a series of our key technologies to deliver exceptional sound quality, power and value in a wide range of demanding applications. Combining a state-of-the-art, DMA-optimized long excursion driver with a highly efficient, proprietary switching amplifier, E-Subs deliver a level of performance that belies their compact dimensions and cements their value.

    Soundstage Hi-Fi reviews JL Audio's E-112 (1500w) active subwoofer

    "The main deal here is that 12” driver. I was told that JLA spent lots of time and effort engineering a woofer that could match the 3” peak-to-peak excursion of their W7-series woofers."

    "There’s no question that, in a high-end system, the e112 can serve that purpose with aplomb. In fact, I wouldn’t hesitate to dial back the crossover to 40Hz and use the e112 with three-way floorstanding speakers with greater bass capabilities than the Magico S1’s. I think the e112 would still be quite a plus."

    "To test the e112 in this respect, I chose Jack Johnson and Friends’ Sing-A-Longs and Lullabies for the Film Curious George (16/44.1 AIFF, Universal). The song “The 3 R’s” begins with a deep, tight kick drum that satisfies my inner need for bass impact. I listened to this track at peaks of about 95dB (at the listening position), and the tapestry of the music held together just perfectly. I felt the impact of each drumstroke in my chest and gut, just as I should, but there was zero muddying of the overall sound. Not once did the music become boomy or inaccurate in pitch. When Johnson’s voice entered, there was crisp, clear fidelity, with no unpleasant interactions between the e112 and the main speakers."

    "I was thoroughly impressed with JL Audio’s E-Sub e112 subwoofer. It provides true supersub performance in a handsome package that."

    "The JLA e112 could open up your speaker-buying possibilities, too -- you don’t have to buy that last octave. I certainly had a great time matching them with a super-resolution speaker like Magico’s S1.

    At the end of the day, the E-Sub e112 is an output beast with fidelity to match. That’s worth the asking price in most any system. In fact, its performance makes the e112 the no-brainer buy of the year."

    Home Theatre Hi-Fi reviews JL Audio's E-112 (1500w) active subwoofer

    "Let’s start by talking about the driver. This E-Sub E-112 sub is a sealed design with a custom-built long-throw 12″ driver. The most obvious peculiarity is in the driver’s depth. This massive driver nearly fills up the cabinet due to its deep motor structure. There are several reasons for this depth: First, the motor structure is designed to support the driver’s substantial 2-1/2″ peak-to-peak excursion with excellent linearity. Another reason is that the depth allows for the dual spiders which are spaced 6″ apart. The additional spider prevents twisting of the voice coil under the demanding acceleration-induced forces that come into play at higher SPL’s or during quick transients."

    "In the stages where the metamorphosis was really taking hold, the wholeness of the bass sent chills up and down my spine with every beat of the black swan’s wings."

    "Pipe organ is one instrument where a sub can actually enhance the realism (not just the impact) of music. In this case, the E-112 sub reinforced the sense of space as it should.

    But of course you are wondering if the E-112 sub was able to produce the entire frequency range of the pipe organ. The answer is a resounding “yes”! The E-112 sub filled in the fundamentals produced by the lowest pedals as heard in the final third of “Guilmant Final” or the opening bars on “Liszt Prelude & Fugue on Bach”."


    "The JL Audio E-112 subwoofer impressed me with its output capabilities and tuneful nature. There is no question that this driver, amp and cabinet system represents a holistic subwoofer system that is designed and focused on delivering high octane thrills."

    "So if you are looking for a compact and nice looking sub for your home system, the E-Sub E-112 is worth serious consideration and the very accessible price point makes it an even easier choice."

    The E-Sub subwoofer driver features a radical, deep architecture designed to create a highly linear, mechanical action and a motor design with enough linear excursion to handle the challenging program material.

    A totally new switching amplifier was engineered for the E-Subs, with a compact and efficient switching power supply. This design allows us to keep the E-Sub's dimensions compact while delivering ample clean power that will fully exercise the drivers' excursion ranges.

    The E-Sub's feature set has been designed to allow the use of E-Subs in a wide range of applications, from full home theater systems to dedicated two-channel music systems, to desktop audio workstations. A true, two-way onboard crossover with high-pass line outputs allows the E-Sub to integrate seamlessly with two-channel systems, and high-level inputs even make it possible to add an E-Sub to systems lacking line outputs. Polarity and variable phase controls make it possible to precisely blend the E-Sub's output with that of your main speakers.

    Every E-Sub is precision-built in JL Audio's U.S. factory and individually performance-verified and tested to deliver years of listening enjoyment in your home audio or home theater system.

    JL Audio CR-1 Active Subwoofer Crossover

    The lucky few who have heard a well-integrated subwoofer in a great audio system know that the subwoofer's effect is profound. While everyone expects the bass extension to improve, most are shocked at the transformation that occurs in the main speakers. They simply open up, delivering improved dynamics, superior imaging and more low-level detail. Many describe it as the greatest speaker upgrade they have ever made.

    Over the years, we have calibrated many subwoofer systems in highly critical listening environments, and we have been frustrated by the limitations of active crossovers we have worked with. Tired of struggling with "blunt instruments", we felt that a higher precision tool was needed, so we decided to build it and call it "CR-1". When properly set up, CR-1 creates a listening experience in which the subwoofers and main speakers become one, delivering a cohesive and compelling sonic presentation.

    JL Audio CR-1 Active Subwoofer Crossover

    CR-1 is built around two banks of precision Linkwitz-Riley low-pass and high-pass filters. Multiplying DACs with monolithic ratio matching are employed to adjust the analogue circuit's filter frequencies. This offers superior tracking behaviour and far more precise left/right channel balance, compared to conventional approaches.

    Another of CR-1's unique and powerful features is a pair of rotary controls that control the damping of each filter bank. These damping controls dramatically improve the acoustic summing through the crossover region, by compensating for each speaker system's frequency response. At the center of the front panel, a single intuitive, rotary control permits quick adjustment of the relative level between the subwoofer(s) and main speakers.

    To minimize distortion and noise, CR-1 employs top-grade component parts in its all-analogue audio circuitry: 1% precision resistors, JFET-input audio-grade op-amps, polypropylene film-and-foil capacitors and metallized-polypropylene film capacitors, to name just a few. We also build CR-1 right here in the U.S.A., to ensure top quality and dependability.

    CR-1's input-output design makes it equally adaptable to studio, mastering suite or audiophile two-channel playback environments. To accommodate dual-mode systems, we also include a bypass feature that engages a pass-through from a dedicated "Managed Bass Input" on the rear panel, to the CR-1's subwoofer outputs. This makes it convenient to switch from two-channel to multi-channel mode.

    CR-1 is the ultimate tool for subwoofer integration.

    JL Audio Fathom® v2 -

    The challenges associated with designing high-output compact subwoofer systems can be quite daunting. In most cases, designers sacrifice low-frequency extension or output capability in order to keep the design small.

    The Fathom® v2 subwoofers sacrifice nothing, thanks to the dynamic advantages of their proprietary JL Audio woofers. These exceptional drivers allow for a true subwoofer passband and very high output, while keeping distortion well below audible thresholds. To extract full benefit from the excursion envelope of its woofer, each Fathom® v2 employs an exceptionally powerful switching amplifier with a large toroidal transformer and a patented circuit designed to enhance control and fidelity.

    The compact design and conventional form factor of the Fathoms apply beautifully to most home theater applications, including built-in designs. Front-mounted controls make them a dream to set up and adjust, while JL Audio’s exclusive Digital Automatic Room Optimization circuit makes sure that response is smooth, even in challenging rooms.

    Simply put, Fathom® v2 is the compact subwoofer system for those who enjoy demanding program material and won’t settle for compromises.

    W-Cone (U.S. Patent #6,496,590)

    Summary:
    The W-Cone is a unit-body cone assembly that delivers astonishing cone stiffness with minimal mass. The shape also provides superb torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits.

    Detailed Information:
    The more excursion and motor force a speaker has, the more important cone rigidity becomes. The acceleration forces are extreme, requiring the cone to withstand rapid changes in speed and direction without deformation. Deformation not only leads to distortion, but can also affect the speaker's mechanical integrity by allowing the voice coil to go out of alignment and rub on the top-plate and the pole-piece of the motor.

    There are several approaches to enhancing cone rigidity. The obvious ones are using a thicker material and/or a stiffer material. In recent years, several manufacturers have used composite cone materials (Kevlar®, fiberglass, etc.) or metals (aluminium, magnesium, titanium alloys). The use of these exotic materials is typically accompanied by marketing claims that the material chosen has exceptional stiffness-to-mass characteristics. These are true statements, but can be misleading. While these materials have excellent stiffness-to-mass properties (compared to paper or poly), they are not lighter than paper or poly in practice. This means that their use accepts the compromise of added moving mass on the design. This leads to efficiency penalties and suspension complications (it's harder to keep a heavy mass aligned properly).

    A simple poly cone diaphragm, while sufficient for lower power designs, would not remain rigid under the demands that the W7 design requires. Our engineering team knew that high levels of cone rigidity would be needed, but they focused on achieving rigidity without a huge weight penalty. This ultimately led to the design we call the W-Cone. The W-Cone assembly achieves its rigidity through architectural means, rather than through inherently stiff materials. The design addresses the stiffness issue by using two lightweight mineral-filled polypropylene skins, bonded together at the perimeter and the centre of the assembly. The lower skin's cross-section is shaped like a 'W', hence the name, and provides incredible rigidity when bonded to the dished upper skin. The effect is not unlike the trusses of a bridge or the unit-body construction of a modern automobile. In addition to the overall rigidity benefit, the lower skin's shape distributes the force generated by the coil and motor more evenly than a typical diaphragm. The force is not only applied to the apex but also distributed to the perimeter of the outer diaphragm for more linear behaviour. A further benefit of the W-Cone is that the upper skin (the one in contact with the listening environment), is isolated from the high air-pressure gradients of the enclosure, further reducing deformation (and distortion).

    As a point of comparison, the W-Cone assembly of a 12W7 is 32% lighter than a typical aluminium-alloy 12-inch cone. If analysed in terms of weight per square inch of piston area, the W7 cone-body weighs 1.24g/sq.in., compared to 1.45g/sq.in. for an aluminium-alloy cone and 1.66g/sq.in. for a titanium-alloy cone.

    So why polypropylene? As stated above, our patented W-Cone technology achieves all of the benefits of more exotic materials while better suiting the unique nature of the W7. Since the W7 surround is detachable, the moving system (including the diaphragm) is subject to mechanical stress unseen in conventional designs. Because the user can tug on the cone while manipulating the surround, the cone must be able to handle this without buckling or deforming. Paper, metal or brittle composite cones would not handle this well. Our two-skin unit-body cone design achieves outstanding axial and torsional stiffness to withstand all kinds of abuse, and will remain largely unaffected and unblemished.

    Dynamic Motor Analysis - DMA Optimized Motor

    Summary:

    JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modelling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.

    Detailed Information:
    Since 1997, JL Audio has been at the forefront of Finite Element Analysis-based modelling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the "Loudspeaker Genome"... a project aimed at understanding the true behaviour of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.

    DMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, "big-picture" solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behaviour under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modelling routines are intense, requiring hours to run for a whole speaker.

    DMA is able to analyse the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the "fixed" magnetic field. This delivers intensely valuable information compared to traditional modelling, which assumes that the "fixed" field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this "fixed" field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analysing this behaviour is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behaviour:

    1. Linear motor force over the speaker's operational excursion range
    2. Consistent motor force with both positive and negative current through the coil
    3. Consistent motor force at varying applied power levels

    Our ability to fully analyse these aspects of motor behaviour allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.

    The payoff is reduced distortion, improved transient performance and stellar sound quality.

    CR-1 is the ultimate tool for subwoofer integration.

    JL Audio Reference Gotham® v2 4500w active subwoofer


    JL Audio Reference Gotham® v2 4500w active subwoofer

    JL Audio Reference Gotham® v2 4500w active subwoofer -

    The Gotham® v2 is the maximum, unfettered expression of JL Audio’s deep commitments to beautiful design, exceptional build quality and truly great audio.

    Whether your listening goals are musical or cinematic, the Gotham® v2 delivers an intoxicating combination of texture, tightness, dynamics and extension.

    The Gotham® v2’s massive fiberglass-composite enclosure is hand-finished in luxurious gloss-black and complemented by machined aluminium and stainless steel accents. The look and feel is elegant and spectacular at the same time. More importantly, this beautiful cabinet houses a pair of JL Audio’s highest-technology subwoofer drivers, each with over four inches of peak-to-peak excursion capability. The Gotham® v2 amplifier offers a mind-numbing 4,500 watts of clean, controlled power, while a completely new signal processing system, employs DSP for all functions. This system includes a more powerful, digital version of our automatic room optimization technology, with 18 bands of response correction to flawlessly integrate the Gotham® v2 into your room’s acoustics.

    As always, listening to a Gotham® v2 reveals an entirely new dimension of subwoofer performance... a dimension so satisfying that listening to lesser subwoofers will forever become an act of compromise.

    JL Audio Reference Gotham® v2 Powered Subwoofer with Dual 13.5-inch Subwoofer Drivers, 4500 watts -

    Your first look will tell you that you are looking at something special... your first listen will confirm it beyond a shadow of a doubt.

    The beauty of the Gotham® v2 extends well beyond its exotic design and exceptional craftsmanship, aiming right at the emotional core of musical and cinematic enjoyment. This is a subwoofer system with limits that exceed the needs of the typical home theatre application, delivering a weight and integrity of reproduction that can only come from a system that is always in control. Its allure lies as much in its ability to convey subtleties as in its prodigious output capabilities. It is simply devastating.

    A luxurious, handcrafted gloss-black finish is complemented by machined aluminium and stainless steel accents for a look and feel that fits perfectly with the finest home furnishings. More importantly, the beautiful cabinet houses a pair of JL Audio's highest-technology subwoofer drivers. When demanded by program material, the Gotham v2's prodigious switching amplifier can deliver 4500 watts of RMS power, to take full advantage of the twin drivers' four inches of peak-to-peak excursion capability. This ensures that the Gotham v2 can breeze through material that makes other subwoofers go into clipping, limiting or distress.

    A very complete set of signal processing features is easily accessible on the top surface of the Gotham v2. These include a highly flexible low-pass filter, variable phase, switchable polarity, e.l.f. trim and our powerful Digital Automatic Room Optimization (D.A.R.O.) system. A calibrated microphone is included for the D.A.R.O. system. Input connections are made via unbalanced RCA connections or balanced Neutrik® combo XLR/TRS jacks. Also included is an XLR output to connect a second Gotham® v2 as a slave unit.

    Listening to a Gotham® v2 reveals an entirely new dimension of subwoofer performance... a dimension so satisfying that listening to lesser subwoofers will forever become an act of compromise.

    Finish: Gloss Black, hand-finished to the highest furniture-grade standard.

    Grille finish: Black fabric (separate grilles for drivers and controls)

    Enclosure Construction: Fiberglass, 2-inch (52 mm) wall thickness

    JL Audio CR-1 Active Subwoofer Crossover -


    JL Audio CR-1 Active Subwoofer Crossover

    The lucky few who have heard a well-integrated subwoofer in a great audio system know that the subwoofer's effect is profound. While everyone expects the bass extension to improve, most are shocked at the transformation that occurs in the main speakers. They simply open up, delivering improved dynamics, superior imaging and more low-level detail. Many describe it as the greatest speaker upgrade they have ever made.

    Over the years, we have calibrated many subwoofer systems in highly critical listening environments, and we have been frustrated by the limitations of active crossovers we have worked with. Tired of struggling with "blunt instruments", we felt that a higher precision tool was needed, so we decided to build it and call it "CR-1". When properly set up, CR-1 creates a listening experience in which the subwoofers and main speakers become one, delivering a cohesive and compelling sonic presentation.

    The CR-1 Active Subwoofer Crossover has been designed by audiophiles, for audiophiles. We believe it has no equal, offering a powerful combination of subwoofer/satellite tuning features, and a complete commitment to analogue signal purity.

    JL Audio CR-1 Active Subwoofer Crossover


    JL Audio CR-1 Active Subwoofer Crossover

    CR-1 is built around two banks of precision Linkwitz-Riley low-pass and high-pass filters. Multiplying DACs with monolithic ratio matching are employed to adjust the analogue circuit's filter frequencies. This offers superior tracking behaviour and far more precise left/right channel balance, compared to conventional approaches.

    Another of CR-1's unique and powerful features is a pair of rotary controls that control the damping of each filter bank. These damping controls dramatically improve the acoustic summing through the crossover region, by compensating for each speaker system's frequency response. At the center of the front panel, a single intuitive, rotary control permits quick adjustment of the relative level between the subwoofer(s) and main speakers.

    To minimize distortion and noise, CR-1 employs top-grade component parts in its all-analogue audio circuitry: 1% precision resistors, JFET-input audio-grade op-amps, polypropylene film-and-foil capacitors and metallized-polypropylene film capacitors, to name just a few. We also build CR-1 right here in the U.S.A., to ensure top quality and dependability.

    CR-1's input-output design makes it equally adaptable to studio, mastering suite or audiophile two-channel playback environments. To accommodate dual-mode systems, we also include a bypass feature that engages a pass-through from a dedicated "Managed Bass Input" on the rear panel, to the CR-1's subwoofer outputs. This makes it convenient to switch from two-channel to multi-channel mode.

    CR-1 is the ultimate tool for subwoofer integration.
