18" Three-Way Speaker


The SRX738 combines the performance of a subwoofer-equipped system with single-enclosure ease of use. The 2268H 457 mm (18 in) patented* Differential Drive woofer delivers impressive low-frequency extension without a sub. The midrange is covered by JBL's CMCD Cone Midrange Compression Driver technology using a 2169H 203 mm (8 in) driver. The CMCD design provides very low midrange distortion, increased sensitivity, extended bandwidth and improved phase coherence. The multi-band, Progressive Transition waveguide assembly also hosts a 75 mm (3 in) voice coil 2431H compression driver.

Bi-amp or full-range passive operation may be selected by means of an internal network mode selector.

For applications requiring suspension, a flying version, the SRX738F 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 JBL's 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.
