Perfect for vocals, DJ/nightclub, PA, and stage monitor applications, QSC’s new HPR122i powered loudspeaker can be pole-mounted using a stand socket, or flown with the aid of nine integral M10 suspension points.
Built to meet the same demanding specifications used to create the RMX line of amplifiers, the HPR122i power module provides a total of 500W. Offering those who might be considering plastic-box speakers an opportunity to upgrade to the professional performance and appearance of a higher-powered, plywood enclosure system without paying a large weight and cost penalty, the HPR122i is operable between 53Hz and 20kHz.
Equipped with a 12in. low frequency driver featuring a 3in. voice coil and neodymium magnet structure, the two-way enclosure features a compression driver with a 1.4in. diaphragm coupled to a 75-degree conical horn at the high end.
Unlike some powered loudspeakers incorporating low-cost “chip amps”, the HPR122i’s proprietary power module incorporates the same circuit designs used on QSC’s top-selling RMX series amplifiers. Thick, deeply finned aluminum heat sink extrusions offer mechanical strength and an abundance of surface area that promotes cool operating temperatures, even when the loudspeaker is pushed to extremes.
Looking beyond its capacity to produce sheer power, the module additionally includes sophisticated signal processing functions that have been mindfully tailored to the loudspeaker system’s specific needs: Each amplifier channel, for instance, is equipped with its own limiting within parameters optimized across the operable bandwidth.
Constructed of premium birch plywood, the HPR122i enclosure features a black textured paint finish and 16-gauge perforated steel grille. Ergonomically-placed handles enhance portability, while the cabinet’s nine threaded M10 inserts facilitate a wide-ranging number of suspension options. An LED power indicator is mounted on the grille that can be turned off as needed via a rear-panel switch.
