The SRX728S is a high power subwoofer system containing two 2268H neodymium magnet 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-requency 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. Pull over padded cover included.
