Embracing the concept of a three-way, direct radiated bass system in a behind-the-screen application, the KPT-535-T utilizes the KPT-904/940-LF double, 15-inch, low frequency system. Reproducing the critical dialogue range is the KPT-402 mid-bass Tractrix® Horn coupled to the Klipsch K-1133 two-inch-exit titanium compression driver. The high frequencies are easily handled by the Grand-HF-T Tractrix Horn. The KPT-535-N is a bi-amp version of this way system, with a passive crossover between the mid and high frequency horns.
