QSC HPR181W 18" Powered Subwoofer
The HPR181W single 18" subwoofer offers truly impressive low frequency extension and output, pounding out 700 watts of program power. The 4" voice-coil driver produces 134 dB SPL peak, at 1 meter with frequency response down to 39 Hz. The HPR181W also includes a top-mounted 35mm pole socket and heavy-duty 3" casters to facilitate load-in and load-out.
For high-level dance music or reinforcement of bass instruments and kick drum, an HPR series subwoofer will add low-frequency extension and power to any sound system. Flexible input signal processing and connectivity allow the subwoofers to be used in systems consisting of a single sub and two tops or larger systems employing multiple subwoofers. The signal processing complement includes a stereo electronic crossover with balanced line-level outputs for connection to any powered two or three-way mid/high speaker.
All HPR models are constructed of 13-ply birch. The speaker components are protected by a heavy 16 gauge perforated steel grille with a distinctive and professional appearance. A grille-mounted power LED may be disabled by means of a rear-panel switch when desired.
Every HPR model is built around a high-power, reliable QSC power module using the same top-quality components and design standards as QSC rack-mount amplifiers. Thick aluminum heat sink extrusions with deep fins provide mechanical strength and plenty of surface area to keep the module running cool. While many powered speaker amplifier modules use low-cost “chip amps”, the HPR series features discrete component designs that deliver the best possible performance even when pushed to the limit. The power modules incorporate sophisticated signal processing functions carefully tailored to the loudspeaker system. Each amplifier channel includes its own limiting with the parameters individually optimized for the frequency band.
