PRE-OWNED JBL SRX718S in VERY GOOD CONDITION – contact for inquiries


JBL’s SRX718S compact, high power subwoofer containing a 2268H neodymium magnet, patented* Differential Drive, 18" woofer in afront-loaded, vented enclosure. The enclosure is designed to present a minimum frontal area. The system offers complete input connection flexibility for compatibility with a variety of cabling schemes. A recessed, external switch allows selection of either contacts +1/-1 or +2/-2. The SRX718S is equipped with a top-mounted, threaded, 20 mm socket that can receive the optional SS4-BK pole. This adjustable height pole can be used to mount speakers equipped with standard 35 mm pole sockets and weighing up to 50 kg (100 lb). The threaded socket minimizes buzzing and rattling and assures that the pole will be secure and straight. The enclosure is constructed of top-quality birch plywood, coated in JBL’s rugged DuraFlex™ finish and is heavily braced to maximize low frequency performance. The attractive CNC-machined, 16-gauge steel grille is internally lined with acoustically transparent foam to provide additional driver protection and give a very professional appearance. The rear of the enclosure is fitted with T-nuts which may be used to attach the optional WK-4 caster kit.
