The SRX725 is an excellent choice when the application calls for high performance and simplicity. A pair of SRX725s and a single, high-power amplifier is a complete sound system capable of reinforcing bass and kick drum or playing high-level music in clubs and other venues. The SRX725 is comprised of two 380 mm (15 in) 2265H patented* Differential Drive® woofers with combined power handling of 1200 watts (continuous). For the high frequencies, the legendary 2451H 102 mm (4 in) voice-coil, neodymium compression driver is mounted to a 75° by 50° aluminum horn. The 75° coverage angle of the SRX725 is wide enough to provide coverage of an audience when used one-per-side yet narrow enough to allow splaying of multiple enclosures without excessive coverage overlap.
