Thanks, Dracule1! I've been meaning to mention Roger Sanders' creations, the InnerSound and SandersSound speakers. Both his former and current company implement true TL woofer alignments.

I've spent a lot of time with Roger at the shows over the past couple of years, as we've shared rooms, meals, rides, etc., and we've discussed a lot of things in detail. His theories on TL design, as well as the implementation thereof, are spot on. The sonics speak for to that. I highly recommend his products to anyone.

Sanders had written some excellent/in depth articles on TLs and electrostatics that appeared in Speaker Builder mag, back in 1980(or so). Those were what led me to experiment with them and the(afore mentioned customer's) Acoustats.

You are better off designing and building a TL yourself then buying a commercial version. Most commercial TL's are undersized.

I understand the Rega Ela is a TL.

Does anyone know if there any good?
