Transmission line woofer enclosures are a way of effectively doubling the size of the woofer by turning it's back wave around and getting it to come out in phase with the front wave at the "right" frequencies. It is a very difficult design to get right and requires a lot of trial and error fiddling. It is best to keep the woofer under 200 Hz or too much coloration will get into the midrange. Done right it can make a smallish loudspeaker much more powerful. The best one I have heard is in Roger Sander's Model 10 ESL. He bi amps them and uses a dBx Driverack as a crossover.
Transmission line speakers!
Hi group,
I just pulled the trigger on a mint pair of Falcon speakers. They are a transmission line design. I don’t see many speakers using transmission line. Does anyone here have any experience pro or con with this type of design? BTW, I have always liked sealed type speakers over ported speakers!
Thanks much!
