Description/Published Specs The PS-12 is a 12-inch rear ported design. The manual gives frequency response as 25-150Hz +/-3dB, and amplifier output as 300 watts RMS.
The variable crossover sweeps between 50-150Hz, with excellent 24dB/octave slopes. A “Normal/LFE” switch on the rear panel fully disables the crossover in the “LFE” position.
The back panel has the standard left and right RCA line inputs, but most likely they are summed internally, since back-panel labeling instructs that either the left or right jack can be used for LFE from a Dolby Digital receiver.
