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.

Some full range speakers can sound surprisingly incoherent. Just because there is only one driver insight, you shouldn't assume perfect impulse. I heard one pair at a dealers with tiny a 4 inch driver in a rear hornloaded enclosure and it sounded like cheap stereo, and they were actually selling for over 6000 dollars. At first I thought that they sounded pretty impressive being having such tiny drivers but then I started hearing muddy bass and peaky highs. Totally not worth the hassle, most fullrange drivers are not in phase throughout their range and the bass loading usually usually messes up the otherwise perfect impulse response. You will be better off with multi driver DSP/ time corrected or coaxial designs.
