Engineered to save space, the new KPT-325 is only 12-inches in depth. The system features the KPT-315-LF single, 15-inch woofer enclosure coupled with the KPT-904-HF Tractrix® Horn. Amazingly, this compact combination delivers the same frequency response as the KPT-904 system. The KPT-325 is available with or without a passive crossover.
