Is anyone interested in a high efficiency subwoofer?

I've written a paper that shows how to make a extremely compact subwoofer with
high efficiency. It's not a bandpass, or a horn, but it's similar to both.

Check out my article and let me know what you think. It's a free download of course.

Tom Danley refers to horns as damped resonators. Although using resonant energy for our acoustic means may be abit sinful,I think theres a difference between BP4s and horns WRT response in the time domain,and ofcourse steady state distortion.

Interesting. Il take more of a look later. See hornresp for modeling horns - apparently it agrees well with the quarter-wave.com files.
