This THX®-Certified system is an enhanced version of the KPT-535-T, with a KPT-415-LF quad 15-inch direct-radiating bass unit for greater output in large auditoriums. Yet it retains the smaller system's 24-inch depth, minimizing the valuable theater space consumed by the area behind the screen. The dialogue range is superbly handled by a KPT-402-MF Tractrix® Horn fronting a K-1133 two-inch exit titanium compression driver. And, a KPT-Grand-HF-T Tractrix® Horn ensures smooth, effortless treble reproduction. The KPT-535-4-T is available with or without a passive mid/high crossover.
