Default Ultimate real fullrange driver

Hello,

I am looking for the best fullrange driver that can cover the bigger part of audio frequency range.
I've thought about Jordan JX92S that seems to be a good compromise, little diameter for treble, big Xmax for bass. What do you think about this choice and in which kind of load? Horn, TL or BR. I think the TL or BR is a better choice regarding T&S parameter. I've read elsewhere on this forum that a BR whith a volume of Vas accorded at Fs (15liter, 45hz) makes some people happy. I simulate this on WinISD and it give the better bass response -3dB point at 45Hz.

I think lowther or fostex are very good speaker too, but it seems to be very difficult to achieve good bass with them, too low Xmax. I have not enough room to install something like Nelson Pass's Klein-Horn... Maybe the best solution to load this kind of speaker...

My music taste is a little progressive rock and a lot classical music (I'm a professional violonist in a french orchestra) whith (of course) a preference for violin music. I like to listen the different sound of all the best violonists (unfortunetly almost all dead today ).
For me the best solution I've heard to distingue all this sound difference are esl or magneplanar but I'm sure that a good fullrange can do the same...

Regards
Hugues

Jordans reveal those differences.

I guess Veravox should outperform Jordan, if you like small metal diaphragms. I prefer big paper cones.

I think Fostex F200A is a good candidate, alhtough bit costly. Kloss has written lots about this driver. You can also look at Bob Brines designs for the F200A.

I am currently doing some analysis and tests with the JX92S compensation, but it would probably be next month till I get them boxed for some listening.

Given all the complcating environs in the real world there is no ultimate FR, but other candidates would include Exact, Fertin, Supravox

Default Jordan is excellent......

Don't want to be called an eretic (BTW we are in the full range forum), but i would just drop my impressions on the Jordan.
I've built the Jordan jx 92s TL enclosure according to the jordan site, listened to the smaller MLTL always based on the Jordan, and I have to agree that both these designs are excellent,with just a couple of drawbacks:
- dynamic is limited (and is not a problem of my amp)
- upper register is not so refined as the medium range.
These issue both disappeared once i've realized the Jim Griffin Minimonitor with the AC G2SI.
You will not loose coherency, dynamic is much better, and you gain a very refined treble.
Not from a tonal point of view, but as per the detail, you have something in the range of the Crosby modified Quad ESL63.
A few days back I had the onor of the visit of the director of Padua Conservatory, audiophile Himself and owner of an incredible (=really expensive) system.
He left my house praying me to realize for him such speakers!
With these boxes I've discovered a really new sound in most of the records I own where there are bowed instruments and brasses.
Please note that I have no affiliation with J. Griffin.
Is just that if you need a small detailed and correct system, this is IMHO the way to go. Remember to feed them a least with a very very refined 30-80 W power amp.
Just my 2 cents.

Ciao

Paolo

I forgot to say that the bass range is far way more extended than the one you can achieve with any lowther in 2 meters height horns. This is based on real facts, it's not just supposition.

Dynamics are always limited in with less drivers.

The compensation network on the Jordan site compensates well for the low end. However, you will loss some highs. The Jim Griffin design is a good tradeoff to maintain effeciency and increase dynamics.

If you want to compensate better using the JX92 alone, the efficiency will suffer. This is one thing I am trying to do during my spare time.

Default fx200?

Thanks for replies, very instructive...

Another good candidate is Fostex fx200, but seems to be discontinued...
