Sonance Bandpass BPS-1 in-wall or in-ceiling subwoofer

This subwoofer has been design to be powerful and yet invisible as it can be hidden in ceilings or walls, depending on your preferences. We have not tested it in the field, but if it works as advertised, it might be the ultimate subwoofer for those who want to benefit from a powerful sound system, without showing it off (think classic or minimalist environment). You can find more technical details at the Sonance BPS-1 homepage. When should we start the demolition party?
