A friend of mine ordered a home theater system built around a pair of SoundScape 10's (in hand-rubbed, burled walnut no less). He really wanted a subwoofer. But his wife really did not want "a big ugly box" in her living room.
So I mentioned an idea I had floating around in my mind for a couple of years now. Why not build a subwoofer in the form of a coffee table? You could finish it just like a speaker and perhaps put a nice (heavy) granite top on it.
My friend liked the idea, but wanted a heavy glass top. His wife wanted to get a better idea of what it might look like. So we did up this illustration...

In the end, they decided since they had spent so much already, perhaps the sub would have to wait until later. But I thought I'd share the drawing anyway.
