Crestron Ultimate ASUB10 10 in. Active Subwoofer

The Ultimate ASUB10 is a free-standing active subwoofer with its amplifier on board: 200 W RMS and 400 W peak into a 10 in. carbon fibre driver, reaching 35 Hz at the low end. The cabinet is aluminium and just 3.54 in. deep without the grille, which is what makes it practical to hang flat on a wall rather than hide behind furniture.

Setup is done on the back panel. A two-position switch selects LFE/NAX mode, which bypasses the internal low-pass filter, or Crossover mode, which engages it at a point set by the crossover knob anywhere from 50 to 175 Hz. A polarity switch either maintains or inverts phase, a volume knob trims level, and a 12 V trigger input brings the amplifier up with the system. Stereo RCA line in and line out at 2 Vrms allow daisy-chaining, and a USB Type A port supplies 5 V at 500 mA for the optional SPKA-EXT-WIRELESS kit. Wall mount hardware and rubber feet are both included.
