User manual QSC AUDIO HPR181I DATASHEET

[. . . ] 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. [. . . ] A total of 9 threaded M10 inserts allow for several different suspension options and use with an optional yoke mount. The bi-amplified 15" 2-way HPR152i is a versatile speaker that is at home in nearly any sound reinforcement setting. A high-power low-frequency driver with a 3" voice coil provides extension down to 48 Hz. The 1. 75" (diaphragm) compression driver on a 90° x 60° horn delivers smooth high frequencies up to 20 kHz. The power module includes a 100 Hz low-cut filter for use in subwoofer equipped systems. The HPR153i 3-way loudspeaker is a great choice when the warmth, clarity and projection of a horn-loaded mid-range design is desired. The 15" low-frequency driver provides extension down to 36 Hz while the 6" mid-range driver seamlessly handles the critical vocal region. A 1. 4" (diaphragm) compression driver delivers brilliant top end response. 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 XLR line-level outputs for connection to any powered 2-way or 3-way mid/high speaker. When the requirement is for compact size and tight, punchy low end, the single 15" HPR151i subwoofer is the answer. The HPR151i is capable of producing 133 dB peak SPL with frequency response down to 43 Hz and sound quality that rivals many 18" subwoofers. The HPR181i single 18" subwoofer offers truly impressive low-frequency extension and output. [. . . ] It is not recommended to surface mount the HPR122i on a wall.
