I tried using heavy duty foamcore as the enclosure walls. I recycled these into surround speakers for the home theater, and although they were ugly as sin they actually kind of worked in that capacity.
They were at least partially inspired by the Linkwitz Pluto , though I may have had some other influences at the time because I was coming out of a long period of thinking that transmission line speakers are the best. The original HTguide. The speaker was designed by an extremely experienced electrical engineer, and it allows an unusually steep slope in the crossover to allow a lower crossover point to keep the aluminum woofers happy.
I purchased the cabinets and almost all of the parts from Parts Express, and I just had to cut out and counterbore the two large holes for the drivers.
These are the speakers that I still listen to today, almost nine years later, and now that I have them set up on stands with some good distance from the wall I can say that they sound pretty OK. They scratched an itch, but I knew that I could do better. Part 2a- The LX, compared to what else? Part 2b- sound byproducts All of these speakers deal with the sound radiating from the rear of the speaker by allowing it out into the room where it can bounce around, and it reaches you after some delay and with some attenuation.
Part 2c- Transmission lines Another class of speaker deals with the rear-wave in a different way altogether. Part 2d — The sound in the room The last part of all this that I want to talk about is what happens once the sound is in the room.

There are a couple of problems with that. First, that frequency range is notoriously hard to absorb. Take a look at the ratings for some sound studio acoustic foam ; it has a coefficient of absorption of 0. That four inch thick piece only has a noise reduction coefficient of 0. As the frequency goes down you need a thicker layer of foam or fiber to affect the sound because the wavelength is longer and it interacts with the fibers less.
Second, it happens to be right in the middle of the frequency range of the human voice. Our ears are very well tuned to this range and we do a good job of noticing sounds here. We also tend to listen to a lot of music with voices and I watch Netflix with dialog , so this frequency range gets a lot of exercise. Another class of speaker deals with the rear-wave in a different way altogether.
Indeed, the refinements achieved with these new designs would have been extremely difficult to implement without the new all-active crossover. The Beethoven-Elite's astonishing degree of naturalness is evident even from an adjacent room.
We invite you to enjoy the ultimate marriage of full-range accuracy and musical involvement made possible by the new Audio Artistry Beethoven-Elite.
