Compact size lets the KTP-445U fit where most amplifiers won't.

It's small and compact at only 7-7/16" x 1-1/2" x 2-1/2". The size and flexible wires make the Power Pack an easy choice to save space.

Independent Filters for Rear & Front Inputs

High-Pass selectable switches for Front & Rear allow frequency filtering for a wide variety of speakers. Choose from full range to selectable range: 60Hz, 80Hz or 120Hz to fine-tune your crossover points.
