After Peter Lyngdorf left Tact, he went into partnership with the Steinway piano company to make a line of expensive speakers aimed not at audiophiles but at well-heeled music lovers. I was impressed by what I heard of the first of this line, which incorporates Lyngdorf's RoomPerfect acoustic correction, when I auditioned it in Manhattan a couple of years back, so I wasn't surprised when Steve Guttenberg button-holed me and told to go listen in the Steinway–Lyngdorf room at Axpona.

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.
