Product Description:

Hsu Research originally used this plate amplifier in the popular VTF-3 and VTF-3R powered subwoofer system teamed up with a 12" driver in a vented enclosure. This class A/B subwoofer plate amplifier includes all the features you would expect from a powered subwoofer making it an excellent choice for use in new designs. The stout class A/B topography can produce up to 250 watts RMS into a 4 ohm load (125 watts into 8 ohms). To allow for easy system integration the phase is switchable from 0º to 180º, the low pass crossover is adjustable from 30 Hz to 90 Hz, and there is even a switch to defeat the crossover for use with an LFE output. Weather used as a drop-in replacement or in a custom design, this amplifier is and amazing value.
