This B&H Kit features two Mackie TH12A THUMP 400W 12" 2-Way Active Loudspeakers, a pair of Gemini DJX-05 Professional DJ Headphones, two 25' XLR cables, two speaker cases and two speaker stands. The speakers feature a 40Hz to 20 kHz frequency response, as well as Class-D circuitry that drives the customized 15" woofer. A 2-way bass reflex design affords powerful bass response, while the 1" compression driver provides smooth, wide dispersion. The speakers also feature a bi-amplified design, which provides 300W of power for the woofer and 100W for the tweeter. Plus, the extra accessories included in this kit provide you with everything you need to set up and transport two loudspeakers for an event or rehearsal.
