Room Gain

Room gain is a naturally occurring increase in deep bass energy created by the acoustics of the listening room according to its size. This phenomenon allows a subwoofer to play lower frequencies and produce greater output relative to the rated output by taking control of a room. A sealed home theater subwoofer naturally has a shallower roll-off slope than a ported subwoofer so SVS leverages this by employing sophisticated DSP equalization to tailor the overall shape of the frequency response and roll-off slope of the sealed subwoofer to take maximum advantage of available ‘room gain’.

Properly harnessed and controlled, room gain can greatly enhance the deep bass extension of a sealed subwoofer. Using decades of subwoofer design expertise, sophisticated software and powerful DSP hardware, SVS tailors the roll-off slope of its sealed subwoofers to perfectly complement available room gain, something other manufacturers simply ignore or do poorly. The stunning result is fathomless and completely natural-sounding bass with in-room extension to 10 Hz or even deeper!
