Orange says the SP410’s design avoids the need for a large enclosure because the front speakers’ movement is in phase with the back drivers, which creates an isobaric chamber (that is, a chamber of constant pressure) that functions as an infinite baffle for the rear driver. The result is more energy in the gap, higher sensitivity, lower distortion and better overall performance. Re: Isobaric enclosures. and that I want to prevent the cones of either subwoofer to even come close to touching the bottom of the seat with this enclosure design.
