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 really like the MLTLs(mass loaded transmission line)
Single drivers. On top of that the Baffle step correction
circuit used in the Brine's single drivers makes a positive
difference! It gives the speaker a very smooth character, no
shout or honkiness.

I've owned a pair of GMA's and loved them. I know of one
other Audiogon member who moved from GMA's to Brine's Single
drivers as well. I still think the GMA's are some of the
most well designed speakers out there!

If you like a lot of hi end shimmer, you'll need to add a
tweeter depending on the driver and the age of your ears. As
far as bass goes though,
not all single driver speakers are designed equally. My FTA-
2000s with one 8 inch go into the mid 20 hz range with very
tight and tuneful bass. Once you hear transmission line bass
done right you'll understand.

As mentioned above most won't play at extreme high SPLs. if
you like your music loud. I mean above 100dB or so then look
else where.

I would advise you to listen to as many variations as you
can find in your area, before you drop any funds in the
project. That way you'll know for sure that a single driver
will fit your needs.

Hey Drew if you haven't looked at JohnK's speakers, you should! ;-)
His speakers look absolutely gorgeous!! Wish I could do woodwork like that! Here's a link KCS Loudspeakers

I would have suggested looking at Madisound, but it looks as though their sold out. The last time I checked on the SEAS they were around $1500 a pair.

I concur with the statements about the F200a drivers. I've been listening to mine for roughly 4 yrs now. They've been here longer than any other speaker. You may find a driver with better highs, but the mid-range and bass of these drivers will be hard to beat!
