This house features an alcove in the family room so the
wide-screen TV and components can be built-in flush with the
wall. In-wall speakers are installed beside the
alcove, and in the rear of the viewing area for surround sound.
My plans are to build the subwoofer into the fireplace hearth
extension. It seems to be an ideal location, but its shape
and volume is not consistent with traditional designs. This
project has been deferred until I can learn more about subwoofer design.
A cavity has been prepared in the back wall of the alcove to accommodate the subwoofer amplifier,
a 300
watt KG 5230 model from Madisound.com.

And here's the extension framing. A driver could be
placed at either end, or both ends. Or in the
center. Ten-inch drivers could face outward, or larger drivers
could face the floor with an exit port to the outside.
The width of just the straight section of the cavity is
about 6 ft. The volume of the entire cavity is about 11 cubic
ft. This does not include the much greater volume beneath the
fireplace, which will be walled off.

Eventually I abandoned this subwoofer plan
and decided to build them into the alcove instead. Meanwhile our unfinished entertainment center and fireplace
look like this. |
