Transmission line speakers

I sold the Acoustats some years back, when I no longer had a listening room big enough to let that system breathe(everything sounded best with 3' feet behind, 10' between, 4' open to either side of the panels, and nothing behind my seat for 15'). The TLs were tuned to have usable output down to 16hz(more visceral than audible). I used to listen to a lot of pipe organ music, on vinyl(love direct-to-disc), with the turntable in a separate, attached room to avoid feedback. Those were the days! I'm now using a pair of modded Maggies(excellent speakers), and mass quantities of Auralex. Of course- It'd be a gas to have all my present equipment and cabling(nothing's the same but the TLs) in my old listening room, and be able to swap the Acoustats in for a comparison.

How about electrostatic with build in transmission subwoofer:

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.
