For over a decade, JBL SR and SRX series speakers have represented the best performance, highest quality and most advanced driver technology available to portable PA users. The SRX700 series continues that tradition and moves the bar even higher.
The advanced technology of SRX700 series speakers delivers the power and performance that you would expect from the highest quality, professional rig. At the same time, JBL innovation and design have reduced system weight so load in and out are a breeze. All this performance is housed in rugged birch enclosures for years of superb performance.
All SRX700 2 and 3-way models may be operated full-range or bi-amplified. The selection is made by means of a high-current, recessed switch mounted on the input plate. The switch is accessible while also being protected from accidental mis-setting.
The same switch arrangement is used on the subwoofer to select +/-1 or +/-2 operation.
SRX700 is constructed of top quality birch plywood and coated in JBL's rugged DuraFlex finish. Extensive use of internal braces and bulkheads makes the enclosures extremely rigid. This reduces acoustic losses caused by panel resonance. 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 system to create acoustical interference. The grilles are internally lined with acoustically transparent foam to provide additional driver protection and give a totally professional appearance.
Amplifier manufacturers are building amps that can produce more power at less cost than ever before. The SRX700 series lets you unleash that power with a new generation of very high power low-frequency drivers. That would be enough for most manufacturers, but JBL accomplished this while also greatly reducing the weight of the drivers.
SRX700 uses JBL's parented Differential Drive® woofers with neodymium magnets. Neodymium's magnetic properties allow a few ounces to replace pounds of conventional magnet.
SRX738 - 18" three-way
Combining the performance of a subwoofer/satellite system with a single-enclosure ease-of-use, the SRX738 uses a 2268 18" Differential Drive® woofer for world-class low-end performance, even without a sub. Mids are handled by a 2169 8" driver using JBL's CMCD Cone Mid-range Compression Driver technology that provides very low midrange distortion, increased sensitivity, extended bandwidth and improved phase coherency. The mid-range driver is mounted to a 60° x 40° waveguide hosting a 3" (voice coil) 2431 high-frequency driver.
Ideally suited to sound reinforcement and music playback use where low-frequency extension, mid-range clarity and projection are critical, mobile DJs and musicians will appreciate the simplicity and performance of the SRX738. Sound companies will also find the SRX738 to be a flexible addition to their arsenals.
The SRX738 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.
