The KPT-1201 is a THX®-certified cinema surround speaker system that delivers extended bass response, controlled coverage, and standard SMPTE/ISO 2696 X-curve de-emphasis from an enclosure designed not to appear bulky. Its 12-inch woofer and 1.75-inch titanium high-frequency compression driver coupled to a 100 x 100 Tractrix Horn accurately reproduce the enormous dynamic range demanded by digital sound formats. A protection circuit guards the tweeter from potentially damaging signal levels. The enclosure angles the drivers downward at a 15 angle and is pre-drilled for industry standard mounting brackets.
