When I started my search for in-walls, I found a very great list off this forum showing almost all the manufacturers and links to their websites. While not always helpful, it gave me a starting point. I don't seem to be able to find it right now though. I have found that not many people on this forum have an all in-wall set-up, but many have ideas on what sounds the best. The bad thing is that it's almost impossible to demo these at home. I was only able to listen to Speakercraft, B&K, and Triad. Only the Speakercraft fit into my budget so I went with their MT4 6 for fronts and sides, CRS 6 for in-ceiling rears, and Triad for the in-wall sub. I recoginize the audio compromise of in-walls, but have been pleased with my home theater set-up. A sub is a must. My new Denon 3805 certainly can drive this system with no problems. Take a look at my pics of the set-up. The room is 25Lx16Wx10H.
