JBL SRX738 18″ Three-Way Bass Reflex
Combining the performance of a subwoofer/satellite system with single-enclosure ease-of-use, the JBL SRX738 18″ Three-Way Passive Speaker uses a 2268H 18″ Differential Drive® woofer for world-class low-end performance, even without a sub. Mids are handled by a 2169H 8″ driver using JBL’s CMCD™ Cone Midrange Compression Driver technology that provides very low midrange distortion, increased sensitivity, extended bandwidth and improved phase coherence. The high frequency driver is mounted to a 60º x 40º waveguide hosting a 3″ (voice coil) 2431H high-frequency driver.
Ideally suited to sound reinforcement and music playback use where low-frequency extension, midrange clarity and projection are critical, mobile DJs and musicians will appreciate the simplicity and performance of the JBL SRX738 18″ Three-Way Passive Speaker. Sound companies will also find the JBL SRX738 18″ Three-Way Passive Speaker to be a flexible addition to their arsenals.
The JBL SRX738 18″ Three-Way Passive Speaker may be used in full-range or bi amplified modes with a passive cross-over handling the transition from the mid-range to the high-frequency driver.
Typical 3-way systems don’t cover any more of the audible spectrum than 2-way systems. But the JBL SRX738 18″ Three-Way Passive Speaker uses an 18″ woofer to take the lows down to frequencies that can usually be reached only by a subwoofer.
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.
