The Speaker725 is an excellent choice when the application calls for high performance and simplicity. A pair of spk25s 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 725 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 725 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. Bi-amp or full-range passive operation may be selected by means of a recessed, high-current switch mounted on the input plate.
For applications requiring suspension, a flying version, the SRX725F is available. The F version offers the option of selecting economical, forged eyebolts (not included) for fixed installation or the convenience of detachable track fittings (not included) for portable applications.
The enclosure is constructed of top quality birch plywood and coated in speaker rugged DuraFlex™ finish. The attractive CNC-machined, 16-gauge steel grille wraps around the sides of the enclosure so there are no protruding lips on the front of the box to create acoustical interference. The grilles are internally lined with acoustically transparent foam to provide additional driver protection and give a very professional appearance.
