The DSR215 is a high-power, 2-way active loudspeaker system driven by a new 1300W Class-D amplifier that gives it the ability to output a 138dB maximum peak SPL. It's the perfect solution for live sound applications that require simple setup and powerful SPL levels. Featuring two cast frame 15" woofers, a neodymium compression driver with a large diameter 2" titanium diaphragm, it reproduces a wide frequency range, from powerful well contoured bass to extreme treble with outstanding clarity.
