700W of QSC-quality power and an 18" woofer with a 4" voice-coil combine to shake the foundations of any dance floor or rock club. Its extended 39Hz low frequency response can be harnessed in small or large PA systems with a stereo electronic crossover and flexible input signal processing and connectivity. Controls include gain, low-cut filter, front LED on/off, and power. 3" casters make it easy to move.

Each model in the HPR series features a high-power, reliable QSC power module and equally high-quality speakers. Using sophisticated signal processing each power module is carefully tailored to the speaker system for a matched fit and ultra high-fidelity sound. HPR power modules use the same top-quality components and designs as standard QSC rackmount power amps with thick aluminum heat sinks for quiet, efficient cooling and discrete circuitry for the best performance. All HPR enclosures are constructed using marine-quality 13-ply birch and have a heavy 16-gauge perforated steel grille. A switchable grille-mounted power LED adds a distinctive touch.

I'm a DJ at a local club, and we use some pretty great speaker systems by JBL. They have always been able to blast music without distortion, and they have always kept a nice clear tone, and the subwoofer had a nice meaty thump to it. But after one of the water pipes bursted, half of the speaker system was busted, and i was forced to purchase a few temporary subwoofers and speakers. And seeing that this is one at a reasonable price, i bought 6 of them. And boy, do these subs sound great. 700 Watts max power is fantastic for any mobile DJ and temporary use, and for its size, i think its one of the best subs i've ever used. Putting these speakers next to each other improves the bass tone dramatically, and i really love the tone of this subwoofer. Great sub, and i'd love to have a set of these in my house. =)


Great Sub!

Coming from a professional production background, and often being treating with products from the upper echelons of EAW, and JBL, Has instilled me with a bit higher standard than most when it came time for my band to purchase a better sound system, and not having $$$ for EAW SB1000's or SB850's etc.. But I tell you what.. after auditioning several other brands, this thing smokes them. I am extremely satisfied with my purchase and recommend it to others.
