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.

I have tried Jordan's, 4 JXr6 a side in a line array with peerless 200mm HDS for the bass. They were sent back because they didn't meet the manufacturers specification. The Peerless are now in the computer room on bass and my new speakers in the lounge are Tannoy Canterbury SE's. The only drivers I ever heard that came remotely close to full range with few issues was the Manger bending wave transducer and Ambiance ribbons. Both demand the fastest tightest bass driver crossed over above 100Hz. All so called full range drivers need help in the treble or bass and all suffer inter modulation distortion issues as well as those already mentioned in response to your post. I would not go for the Jordan's unless you hear them first or anything else for that matter until you are sure their sonic signature will satisfy. Building good TL or TQL cabinets takes a lot of effort & fine tuning to get them right. If you are infected incurably with the full range bug. I would try auditioning the following AER, Supravox, PHY, The alnico Fostex full rangers, Feastrex, Visaton B200 which I think offers the best value or the SEAS exotic who at least seem honest with their response curves. If you are open to using vintage drivers or building a line array the possibilities really open up. Madisound has a decent range of things to check out. Don't know if this advice helps or confuses but putting my 2 cents worth in anyway. Cheers thermo

Newbies suggesting Audio Nirvana? I can email you a photo of my Audio Nirvana's. Where are yours? Secondly, only a newbie would suggest fostex instead of Lowthers. Someone needs to finish their educational roadmap.

Apequark Owned most all lowthers except 5in,perfer f200a to all lowther and SEAS x- 1 is even better than f200a, heck I have used most all fullranges of quality available to the public. Since I design loudspeakers many hi-eff or using fullrange transducers and been doing so for near 25 years not a newbie as Apequark suggests. Apequark you sure do need to hear some other drivers than A nirvana drek...And your right you sure do need to finish your educational roadmap....

Dear John,

From reading your response, I would have to agree that I have not heard many single driver speakers. You have the upper hand when it comes to that. Seems though, that may be your only advantage. Let me know when you have graduated from "Not Making fun of People Academy"...then myself and possibly others will deem it worthwhile to respond to your cutesy remarks.

Sincerely,

(so as to help you out...)

Apequark.
