LOW-PASS CROSSOVER AND PHASE CONTROL

HIGH-QUALITY CABINET CONSTRUCTION

Reinforced 3/4-inch MDF construction with all-new bracing reduces cabinet vibration, which reduces coloration and improves sonic accuracy.

THERMOFORMED CRYSTALLINE POLYMER (TCP) DRIVERS

Utilizing trickle-down technology from Klipsch's acclaimed Reference Premiere series, TCP woofers feature steeper cone angles for a smoother response and improved accuracy and transparency. Additional ribbing increases overall rigidity, reducing cone breakup at higher frequencies.
