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!

f200a 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.
Hi, Saki70. The speakers are all tested in our Wh3 enclosures (USPTO Application #: 20080199032) , which you can see here:

They are triangular rear loaded folded horns a little under 10 feet in total length.They don't have any boxlike sound to them.

Johnk, I didn't say the 200a sounds like the fe206; I said that the audio nirvana super 8's sound like the 206. Although we make lots of measurements, it's what listeners tell us that matters. We're not really interested in speakers; we're interested in how people hear and perceive music. One of the most highly rated speakers we use (the altec 755) has the most restricted frequency response of all of them. We know, for example, that the same speaker sounds different to different listeners...
Fe206e & AN SC Hemp 8 incher DO NOT sound the same or even close.
Different drivers for different applications & taste.IMO
Johnk's has his opinions so do I and others. Personally, I like Fe206e in horn loaded designs but that's just me. For what it's worth, AN & Fostex make some affordable drivers for DIY crowd delight. Have fun all.

Hi, JohnK. I didn't say the Fostex 200A sounds like the 206E; I said that the Audio Nirvana Super 8 sounds like the 206E. While you don't care for the 206E, some people prefer them. David, of Commonsense Audio, a dealer for Fostex among other brands -- http://www.commonsenseaudio.com/ -- says this:
"The FE206E is the most detailed, the most extended, the most efficient, the most natural sounding, and has the best bass of all Fostex speakers." So that's what makes horse races. People hear speakers differently, and frequency response alone isn't a good indicator of how good a speaker will sound to any particular person...
Correction:
It suppose to say AN Super Alnico 8" driver.
And again - fe206e and above mentioned do not sound the same .... - presentation wise.
