bandpass enclosures

built for sound quality and eliminating trunk rattle.

Often referred to as "cheater boxes" due to their high efficiency, we use these in a different way. When designed correctly, a 4th order bandpass enclosure can deliver a very even frequency response with plenty of volume. It ports the sound directly into the cabin in sedans so that there is no sound or loss in the trunk. Everybody wins!
