One reason for this project (beside the other 50 projects I'm working on ;-) ) is Floyd Tool's book "Sound Reproduction" where he discusses multiple subwoofers in a room to diffuse or spread out room resonance modes to greatly improve low frequency response flatness and accuracy. There is also an excellent thread on this subject here, where, among others, Earl Geddes offers an empirical method to set up such a system with multiple subs.

The cone is about 80 cm high, with an internal volume of some 78 liters. I have designed a wooden adapter ring that accepts the excellent Peerless XXL 12 inch woofer.

... and this is how they came back from the paint shop in a coat of BMW Arctic Gray.
