JBL SRX718S subwoofer.

The JBL SRX718S subwoofer's compact design is equally at home as a small, high-performance satellite subwoofer system or as a building block for larger subwoofer arrays. The 13-ply birch enclosure is rigidly braced for solid response. A top-mounted, M20 threaded pole receptacle is used to ensure that even heavier, high-power satellite speakers can be securely mounted using the optional, adjustable SS4-BK speaker pole. Threaded insert points are provided for attachment of the optional WK-4 wheel kit.

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. 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.

High Power: 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.

Incredibly Lightweight: 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.

Connectivity: All SRX700 Subwoofers have a high-current, recessed switch mounted on the input plate. The switch is accessible while also being protected from accidental mis-setting. The switch arrangement is used on the subwoofer to select +/-1 or +/-2 operation.
