For those performance situations where additional low-frequency output and punch are required, even beyond the already-impressive bass capability of the TS2 full-range speakers, the new TS2 powered subwoofers are the perfect solution. Pair TS215S with any full-range speaker system to extend the bass response and dramatically enhance the overall impact of the music being played. TS215S Features include: · 1250 watts of peak power output · Custom engineered high-efficiency Class D amplifiers with passive cooling design - no fan means the speaker runs cleaner, quieter and has greater long-term reliability · 15-inch high-excursion woofer · (2) XLR+1/4-inch combo inputs + (2) balanced XLR line outputs · Polarity Reverse, Full-Range Output and Extended LF controls · Electronic clip, thermal and transducer overdrive protection · Rugged, internally-braced front-ported plywood cabinet · Integrated 35mm speaker pole socket
