Thread: Midbass Horns and Real Estate.

It is very self-explanatory and liked it a lot. The advantage is that it might be used in any rectangular room and the most important that it is VERY simple to build this way. I think that if I have room then I might stop by in a local architecture shape and proposing a few cases of beer I might recruit local students to build foe me a set of plaster walls like this. The wall insets might be even easily removed if I wish so. Very cool!

I llike this solution too. As mentioned, horn length is the biggest problem with the other designs shown above. If I were doing this, I would want at least 9 feet of length. Alingment is another problem. Maybe an all pass filter could help here without messing things up?
