Opinions on Full-Range/single driver speakers

I am considering a DIY project to build a pair of single driver speakers. My current idea is to put Jordan JX9s into Transmission line cabinets. I am a competent woodworker and there are lots of plans on the internet.

I do really value the opinions of you audiogon members out there with lots of listening experience so I am curious what your opinions are on single driver speakers. If you can also comment on wide-baffle versus narrow baffle designs, that would be helpful.

My front end is a Monarchy tube DAC 25 with Matsushista tubes and DIP Classic, coupled to an AYRE DX7E, all interconnects and cables are DIY magnet wire. I am currently using Green Mountain Europa's and a modified Paradigm subwoofer.

After enjoying GMA's and experiencing time/phase coherent sound, I started looking at other options for coherent systems. It seems the simplest design is a good full range driver (no whiffle cone) in a TL or QWL cabinet.

So your opinions are appreciated. I would prefer if you did not advise me to purchase your favorite speaker as that is not the type of information I am seeking.

Thanks in advance for your time!

Drew.

Whew! The lengths we grown men go to, defending our passionate beliefs!
I have a pair of blh fostex 166's, my friend made the 206 model (sachikos), and we both prefer the 166's, funny , in the workshop the 206's KILLED the little 166's... But I guess those high ceilings and vast space had much to do with it.
I've just recently heard some tannoy 15" speakers and, wow.
I'm thinking I may chuck a pair of AN 6.5 alnicos into my blh cabs (hiro design @ frugal horn site) and see if I like what they do for me.
I will report my findings.

I just LOVE my NEW improved 901 series 6 version 2's ! I have been to all the shows and listened to other speakers BUT I would not trade my 901's for any other speakers on the world market.. PERIOD !...

johnk1,618 posts10-06-2009 7:30amf200a and fe206 equal in performance? My findings are fe206e has +12db peak in responce from flat. If you like that great. I dont. Use a notch filter takes away the air. Using in front horn reduces peak to a small degree but still measurable and audible. To me fe206e is 1 of the worst sounding fostex I much perfer fe166e over fe206e but sure some are groving to the peaky responce of fe206e maybe the rise adds a bit of color that others like I dont know. But I will pass on fe206e.

Fostex to this day is still trying to figure a speaker w/o certain peaks in some fq.s the **Shouty-iness** which has plagued so many of their speakers.

Any speaker compamny that feels the need to invest so many *New and Better* models,, tends to raise the old red flag in my book.
.
Why?
Can’t they find the magic formula, considering Fostex ain't no new kid on the block. 
Vs a new recent competitor, The Davidlouis line. 
The Davidlouis VX8, one model, 2020.
VX6 one model /2020.
Thats it, Apparently DavidLouis figures here are our best results. 
 If don’t like either then go Fostex.
Good luck in that jungle.
Tang band also has/had some issues which is why they offer many models. 
However I think they really found a  winner with the 2145. 
I bet the Tang Band 2145 beats the best Fostex W8.
TB2145 has zero shoutyiness. That alone beats most Fostex.
I think Fostex might have a **house sound** and they can’t figure out how to get rid of their trade mark of The Shout.
Which is why they come out with so many **limited editions** which are high priced and not worth the bang for the buck.
These FR speakers are a mystery and the secret to a high fi sound is a secret, which only a few manufacturers have figured out.
Esoteric.
