4" Subwoofer Legs

A short while ago I mentioned how watching THGttG popped my subwoofer grilles and a desire to do something about it. So over the weekend I increased the leg length of the subwoofer base to 4" (I would have gone with 5" except Home Depot doesn't sell screws longer than 6") and created new end plates and legs for the top of the subwoofer as well. There are no longer any grilles in use.

Increasing the leg length to 4" is based on allowing enough cylindrical surface area for the air displaced by the driver to freely move back and forth. It might have been ideal to go with 5" legs but that would have required 7" screws. As it is, the 6" screws only came with hex heads and required me to cut a little depression into the plates for the head to run flush with the plate surface. The top plate provides protection for the driver in a sturdier and more reliable manner than the grilles and allows the driver to reach its xmax without any interference. The grilles were impeding the surrounds. I do think it looked better with grilles though.
