The ASB6125 is a high power, lightweight front-loaded vented subwoofer enclosure housing two JBL 2265H-1 Differential Drive® dual voice coil dual gap 15" woofers. These woofers feature neodymium magnets and ultra robust cones for extra long life.

The enclosure is constructed of multiply hardwood coated in JBL's rugged DuraFlex finish and is heavily braced to maximize low-frequency performance. The rectangular enclosure is fitted with sixteen M10 threaded attachment points and utilizes a 14-gauge steel grille internally lined with acoustically transparent foam to provide additional driver protection and give a very professional appearance.
