    I did some researching today online at the CULT OF THE INFINETLY BAFFLED and I really liked the in-wall subwoofer that can be built.

    From looking at this thing it consists of two drivers, a box, and an amp that is hooked up to your Receiver. Is that it or am I missing something. it looks as if one can be built with two 15" subs for less than $500.


    Opinions? Testomonials?

    I'd add the air spaces, front and back of the driver, need to be seperate. If there are any moderately sized openings between them, it can cause cancellation issues. Next the air space on each side needs to be big enouh. The minimum is 4x the combined Vas of the drivers used and 10x is recommended. Last make sure you test the location of the manifold with a regular sub first. If you get a bad frequence response there, better to find out before you cut a hole in the wall.
