    Thank you, sir!

    Changed things up a bit...

    Back to using a single NuPrime STA-9, a pair of Magnat Signature 503's, and a single HSU STF-2 subwoofer, getting its high-level signal from the amp. Oh, and of course, my 3rd Pangea Vulcan rack that I bought years back. Everything else remains the same.

    Drove 150 miles round trip yesterday to pick up something I've always wanted...

    Finally found a near mint pair at a extremely good price. Bose 901 Series V with Series VI EQ and tulip stands.










    I've heard the 901's several times before, a few times in Circuit City, and once or twice at the PX at MacDill Airforce Base. I have to say, they sound much better in my room. A lot more natural than in the showrooms. In the showrooms, they probably had the EQ jacked all the way up as well as the tone controls on the gear used with them.

    I have all of the controls on the EQ set to "flat", and I really see no need to adjust them as the 901's sound pretty darn good in this room, the master bedroom. This room is roughly 13' x 16' x 8', and I'm powering them with one of my NuPrime STA-9 amps which puts out 120 watts @ 8 ohms... More than enough power for this room and these speakers. I have the 901's center part of the rear "V" about 31" out from the front wall. This distance also helps in the fact that I'm getting a much more balanced overall response out of them than what I remember in the showrooms.

    The bass is quite punchy, detailed and extends a lot deeper than I expected, easily down to the low 30's, possibly a little lower from listening to a few of my very familiar pipe organ recordings. Midrange seems to sound good, though not quite as full as my Maggies in my main rig. And the treble seems fine to me as well. Obviously, not super airy, but open and extended enough for a pleasant, smooth sound that's non-fatiguing. They're definitely not lacking in either extremes like all of those clowns claim (no highs, no lows, must be blah, blah, blah). I really have no complaints with them honestly. However I do wish those tulip stands were a bit taller.

    I have always been attracted to the 901's unique looks and design, and even more so, their use of multiple 4.5" drivers producing that kind of sound. I mean, I wasn't even playing them loud last night, and not only were both windows in this room rattling, but so were the sliding closet doors and the main door!

    The above was when I was playing Boz Scaggs' Thanks to You. Boz's voice came through loud and clear, and all of those deep bass notes came through effortlessly and with authority.

    This system is by no means a replacement for my mine rig, but it's just about as enjoyable to listen to. I'm glad I finally got my hands on a pair of these little suckers!

    I remember one of Bose's magazine ads from the 1980s where the '901' was inverted and 'db' added, so that the headline read '106db'... Sounds like they weren't far out then

    I don't remember those ads as much as I do the ones with Matthew Polk surrounded by his loudspeakers. One day I'll get a pair of SDA loudspeakers.

    Just threw in a JungSon JA-1 preamp. Quite the solid unit.

    Just replaced the stock Bose Series VI EQ for the 901s with my dbx DriveRack Venu360. Dialed in a quick and dirty rough version of the stock Series V EQ curve, and wow! What a drastic improvement over the stock Bose EQ with this literal 10 minute tuning via PEQ. I have barely scratched the surface with this obviously. When I get more time, I'll do more tweaking in the 8 band PEQ as well as the 31 band GEQ. I'll also try out the AutoEQ (basically room correction) via the included RTA mic. More to come!

    It sounds even better now with the dbx doing EQ duties. Powerful, clean, effortless.

    More pics of the bedroom system... Now sporting my father's vintage Kenwood GE-770B graphic EQ (just for show, not in the signal chain) and my trusty Emotiva XPA-2 Gen 2 amp for some real power to the 901 V's, a solid 300+ watts per channel.

    And for fun out in the main system... Removed the Odyssey Stratos monos and Maggies, and put in the little NuPrime STA-9 amp and GR-Research X-Statik's. Still excellent sound with the rest of the system remaining the same.
