The PS15P uses a high efficiency 15-inch woofer (with 3-inch voicecoil) to deliver extreme low end punch from as small a physical cabinet volume as possible. Wide 85° x 50° (H x V) conical horn delivers improved constant directivity and far better midrange response than competitive cabinets in this class. Integrated DSP ensures the PS15P can operate in any application without complex external processing. A simple one-button high pass filter switch rolls off low frequency material when PS12P is used with any Paraline Series or powered élite System subwoofer. Bass boost delivers remarkably improved bottom end response from the PS15P without cluttering midrange program or affecting the cabinet's overall intelligibility - making it the perfect small speaker solution for larger events where additional subwoofer support is not available.
