[QUOTE="thadman, post: 1965026, member: 561122"] Yes! you lose some efficiency but this idea has been implemented by several reputable home subwoofer manufacturers, such as Bag End (flat to 8hz, without room gain). They use a box that is naturally too small for the subwoofer thus raising the fundamenal resonance of the driver above the frequencies in which it will be used, the subwoofer then predictably rolls off at 12dB/octave without any impendance peaks to get in the way of a smooth response. They then incorporate a linkwitz transform to equalize the response. You lose as much efficiency as you boost (if you boost 24dB @ 20hz, your maximum SPL will be 24dB lower than it would be without the linkwitz transform) You can only have 2 of the 3...
