The S-Series subwoofer-satellite system ($22,100) was producing a big sound with the tiny satellites stood on a credenza against the wall behind them. Incorporating RoomPerfect correction, the speakers also use digital signal processing to produce a flat response, which Peter Lyngdorf explained allowed him to optimize the drive-units for maximum sensitivity. The two small subwoofers were placed in the room corners, with a crossover frequency (depending on the room correction necessary) around 200Hz
