View Full Version : Best dual concentric

In September I plan on trying new speakers (currently Ane spx) and really would like to try high efficiency, point source speakers without crossovers. My budget will be around 3k and I'm happy to buy second hand (though it would have to be eBay as no one ships on AOS).

What are the best available at that kind of price?

Dual concentric speakers generally have crossovers and employ TWO drive units. One (the tweeter) central to the second, the bass cone.

As for full range single drive units, the sky's the limit in choice really. Try Googling and you'll see.

ive loads of full range speaks and they are excellent. some of the old ones like my Telefunken paper coned ones are superb. nice simple sound

I'm looking for simplicity, purity - if full range means no crossover then that's the way I'd go, though I think I'm right in saying that in a dual concentric it's just a capacitor? I'm an idiot when it comes to this particular topic.

I'm not a fanboy of single driver speakers (apart from electrostatics) but by far the best I have heard are by Eclipse. The usual single driver tonal aberrations are largely absent and you get the coherence and purity benefits of a simple basic design.
They look cool, too!

you just have to look at Tannoy crossovers to see its not just a cap. with any fullrange speaker you can add a supertweeter with a cap

Would you consider making your own cabinets or baffles Adrian? Many full range speaker units only require fairly simple enclosures and this brings the cost down if you can do it yourself.

Alpair, Jordans, Corals, I've used them all and enjoyed everyone. They have a real directness about them that just sounds right. When I go back to speakers with tweeters I always struggle a bit getting used to them. I think these will be far too cheap for you but I will be selling a pair of Coral Flat 8 drivers in the near future. Legendary vintage drivers and now very rare but I'm just not using them and they really should be used. Cabinet plans are fairly simple and could easily be made up by a local joiner. Mega smooth and natural.

Guy here made the cabs originally for tannoys, but they didnt work so i got them off him and converted them to my needs. Not the last word in craftsmanship but they are very strong(double the thickness you see) drivers are 10" each. very sensitive at about 97db

Talking of Corals. Here are the exquisite, top of the range Coral Beta 10 ten inch drivers.

http://i63.tinypic.com/2r7vj0y.jpg

And in their horn cabinets, with super tweeter.

http://i66.tinypic.com/jaarn9.jpg

Not an easy build, but it can be done.

Here are mine, built many years ago.

http://i67.tinypic.com/2u8b2ts.jpg

102db sensitivity and superb sound! I should have kept them.

Unfortunately, Coral drivers have been out of production for very many years.

The nearest modern equivalent are the Fostex range. Have a look at this UK supplier, Wilmslow Audio, here: http://www.wilmslow-audio.co.uk/fostex-56-c.asp

I would endorse full range designs. I have Magneplanars as my main speakers and Rogers LS3/5a speakers in storage. However, I can thoroughly endorse the full range speakers produced by this company: http://omegaloudspeakers.com/home.html

They are a direct sell operation with the owner Louis being designer and manufacturer. The quality of construction is superb and the sound quality exceptional. I am on my second pair as a colleague begged to my the first pair I bought when I was working in Malawi. I bought the current pair direct from the Omega factory. They are a custom design (effectively the Super 7 monitor with an Alnico driver). The only criticism I have is that they take a long time to run-in.

I understand that you cannot hear them before purchase, you are welcome to hear a demo of mine if you get back to the UK, but with your budget it would be worth having a break in New York and driving down to hear his speakers at the factory. He has a fantastic collection of vintage valve equipment to demo his products.

Feastrix make beautiful dual cone full range speakers, but only for those with deep pockets. A pair of these will set you back around £40,000 if I recall.

I had my first pair of Omegas (floor standers) shipped via fedex. Beautifully and safely packed no problems. The second pair I brought back as baggage. Counted as 1 of the 2 23kg items allowed on Transatlantic flights. His factory is less than an hour from NYC by car.

The sound quality on both speakers share a family resemblance (the drivers are in house designs) but the Alnico drivers deliver that weighty valve like mid range presence. Dynamics are startling but definitely not shouty. I dislike the Fostex designs for that reason.

If you are seriously considering an Omega design i would give Louis a ring. All of his products are built to order and he has good rates on international shipping. Very friendly guy and can advise on shipping to Spain. Into cars in a big way, he has a Mini Clubman, which is quite surprising given the (poor) quality of many USA roads.

Get in touch via PM if you need further info.

Omega are sold in the UK by Divine Audio (see https://www.divineaudio.co.uk/brands/omega-loudspeaker-systems ), so no customs dramas. I have heard one of the stand mount designs (the Omega Compact Alnico Monitor IIRC) and it was one of those occasionally transcendental audio experiences - just lovely and a beautifully balanced sound but with that single driver musical coherence. As for whizzer cones, I suspect that it's a matter of the overall design, rather than their having any universal or detrimental sonic characteristics.

If you find yourself back in the UK, and knowing the sort of music that you enjoy, I would very much recommend hearing Omega speakers.

I am glad that Louis finally has a UK outlet and that others share my view of these speakers. It must be quite recent as only a year ago they had no UK retailer. It comes as no surprise to me that this dealer is also a Croft dealer. as these speakers really sing with quality valve amplification. I use my Omegas in a vinyl only system powered by an Art Audio Quintet in triode mode and the sound is excellent. What does surprise me is that the UK prices do not carry the outrageous mark ups usually associated with US imports, though I think that the price premiums for some of the more exotic finishes are a little high over the basic models. I know that your budget is 3k but personally I would go for one of the two Alnico monitors. Do try and hear them as I am sure you will be knocked out by their performance.

The problem is that I am now tempted to upgrade to another model in the Omega range. Perhaps it's just as well that Divine Audio don't stock the SUPER ALNICO HIGH OUTPUT MONITOR a 99db efficiency beast.

I like the floor Stander's for their extra extension but love the idea of the SAM alnico montors - I guess room placement could boost their 45hz cut off.

The first pair I had were floor standers (similar to the 3XRS I think). They were fantastic and I am generally of the view that floorstanders are good value because they do not require stands and take up no more space than standmounts. However, I am a big fan of Omega's Alnico driver. Even though the speaker volume of my Super 7 Alnico monitor is less it is certainly not bass shy. Furthermore, what bass there is it tight and rhythmic. I was listening to Rickie Lee Jones Girl at Her Volcano the other day and the dynamics and slam on Under the Boardwalk were awesome. Imaging is fantastic but you do have to pull them into the room and away from walls to get the massive soundstage. On balance I feel my current model is significantly better that the first with no obvious compromise in the bass department.

Now an Omega floorstander with the Alnico drivers .........:drool:

Yes, and simply replaced by those inherent in the design of whatever other speakers you're comparing them with! :ner:

Speakers? None are perfect; ALL are coloured to some degree. Therefore, simply choose the "tonal aberrations" you can live with most...

Best still, forget all about concerning yourself with single or multiple drivers, and simply, with a completely open mind, free from often misleading preconceptions, choose speakers that you like the looks and sound of the most, that work best with the kit you've got, and will fit into your room - end of ;)

Consider looking out for a pair of Goodmans Imagio loudspeakers with their ICT drive unit - they are, strictly speaking, the only true full range driver out there.

I would also advise caution where 'whizzer' cones are concerned. I generally find they are best off left in the front doors of cars where your ankles absorb the worst of their distortions!

Whilst not a fan of the full range drive unit generally I was reasonably impressed by a pair of Goodmans axiom speakers a year or so ago... They could have done with a conventional tweeter taking at say 8-10KHz though IMHO as, whilst not disastrously so, the top end was audibly down on what it should have been...

spendorman
14-05-2017, 20:00
I still have a pair of the original Axiettes, not bad full range, put a soft dome tweeter with them using just a single 2uf capacitor as the crossover. A lot of the better Goodmans units were designed by Ted Jordan, later started up his own company, Jordan Watts.

Don't need a tweeter with my telefunkens

How's about a pic of those telefunkens please Struth ! I've never seen them .

I recently purchased a pair of Goodman Twin Axiom 10's in solid pine boxes with yellow wood framing the funky front grille clothe . The box appears to be the original design for the 10's by Goodman . Round hole for port cut in front baffle with ~shoebox size box as a port inside the bigger box . Something like the 2nd design on this flyer :

http://www.sanyue.net/bbs/images/16_37111_b109c93fe3cc33d.jpg

I've got them driven by Pioneer SM-83 in my workshop , they sound amazing . I push the bass on the SM-83 to 3 o'clock , and reduce treble to 11 o'clock ( where 12 o"clock is flat ) and it then sounds fine . With both flat it can sound a little screechy . Perhaps , when I have time again , I can measure and make a notch filter . but I really am quite happy with the treble a notch down and the bass up - they seem quite efficient too .

A couple of years ago ( probably 7 ) in South Africa a pair of Tannoy Monitor Gold 10's , unused in original boxes , with original crossovers , sold for the equivalent of $500 . I can seriously kick myself for not buying them , they were available for a couple of weeks at that time too . I uhmmed and aahhed about it all too long , and then they were gone . :doh:

Looked something like this ( although these could be 12" or 15" )

I think one needs to make judgements about full-range drivers on an empirical basis rather than making generalisations about "shouty" whizzers and excessively rolled-off treble. Yes some full range drivers do have these flaws but not all do.

Ari I ask a favour of you regarding the picture above of a corner reflex cabinet.

When I was about 9 my Father built a corner reflex which looks very similar to the one on the left in you picture above, but it was for a Godmans 12" unit with a whizzer, and its front panel port opening was up from the base by about 6".

He built the cabinet with the port, up from the bottom by maybe 6", and I believe that he inverted the box attached to the rear of the front panel so that its opening was pointing up to the driver rather than down to the bottom. This I think he did on on the misconception that by having the open end of the port box which had one 'end' missing, upwards instead of downwards, it would 'allow the sound out better'.

Of course it would which ever way up work as a reflex for bass frequencies, but with it upwards the rear cone mid range would also be allowed out, and this is undesired. So I have a question which you may be able to answer.

Do you have any references or diagrams showing a similar corner box but for a 12" unit that will allow me to determine which way up the box should have been placed?

Ari

Many thanks Ari, the 201s do look very similar but my memory is from '57, a long time ago.

The fronts are very much the same from memory, but the frame looks rather sophisticated and possibly slightly later than '57.
The magnet size and frame look very serious in design, and seem to put to shame much of the later stuff we see.

The original cabinet was very like that on the left of your posted diagrams but with the box hole lifted from the base, allowing for my ambiguity question on which way up the box was meant to go.

Oh and it was used with a Williamson amp, 66s or 88s.

These are gorgeous, but you might have a bit of a job tracking any down.

They were available. But not seen them offered for a while. May still be possible to get them from China. None on ebay worldwide for a while. Nor with US sellers. With shipping, duty and VAT they worked out around £400 a pair in the UK.

Having quickly read up on them it seems they need a contour filter to even them out.

Depends on the application. A slight rising response can be useful in a lightly damped large reflex box or backloaded full range horn. Lowthers being an example.

Use of the filter is optional with the L Caos. Some reviews say it's not required or suggest a milder type.

Related, but not the same. That's the 6.5 inch version. My image is of the 8 inch.

Not owned but listened to ANirvana's quite a bit.
IMO (And general consensus) is that their 8" driver is their Best sounding/working speaker.
Like all Full rangers.. Lows and Highs are constrained.. But their 8's exhibit the least of this.
Quite nice/pleasing sounds drivers actually. One can do far worse.

Thanks for the reply Danilo ! Re-assuring to see that your own speakers are Monitor Gold's . :clap:

Specs on the Classic 8+ ALNICO look fantastic !

But then , at $1299/pr , they had better be . :stalks:

In September I plan on trying new speakers (currently Ane spx) and really would like to try high efficiency, point source speakers without crossovers. My budget will be around 3k and I'm happy to buy second hand (though it would have to be eBay as no one ships on AOS).

What are the best available at that kind of price?

The best ones I have had in house, are Fertin field coil drivers FLB20EX (now the LB8EX mark ii (http://www.emspeaker.com/ems_products.html)), AER single drivers (https://aer-loudspeakers.com/aer-breitbandchassis-bd/) with whizzers, and more recently, 12" Isophon Orchesters (2 pairs, alnico drivers, single capacitor crossover)- for which I may finally get some original cabinets built (reflex, about 280+ litres):

I think you can still get these in Europe. In fact, I'm fairly sure NOS items were available in Spain just a few years ago. Like others here, I am a fan of vintage German drivers.

Not seen those. I was looking through Isophon on ebay yesterday. Got a link?

The later Orchester had a dome central tweeter.

I was wondering whether or not you had come to any conclusion as to the speakers you want . So many beautiful drivers !

The other driver I can think of is Decware inhouse field coil driver - although I think there may be a waiting list for those .

I see that Divine Audio have a pair of the Omega Super Alnico Monitors on demo. I may be in their area soon so the temptation to check how they sound compared to my Super 7 Alnico monitor is great. The only thing that puts me off is the price for the dedicated stands for the SAMs.
