JBL SRX728S JBL SRX728S


Product Information
Overview The SRX728S is a high power subwoofer system containing two 2268H neodymium magnet, patented* Differential Drive, 18" woofers in a front-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. By relocating an internal connector, it is also possible to drive each woofer discretely from a separate amplifier channel.

The enclosure is constructed of top quality birch plywood and coated in JBL's rugged DuraFlex finish. Each woofer is housed in an isolated chamber and the enclosure is heavily braced to maximize low-frequency performance. The attractive CNCmachined, 16-gauge steel grille is internally lined with acoustically transparent foam to provide additional driver protection and give a very professional appearance.
