About the JBL ASB7128

The JBL ASB7128 is a high power, lightweight front-loaded vented subwoofer enclosure housing two of JBL's exclusive 2269H Ultra Long Excursion 18" Differential Drive woofers. This woofer features neodymium magnet, dual voice coils and dual gaps, JBL's exclusive Vented Gap Cooling and ultra robust composite cone for high excursion and extra long life. Woofer is capable of a peak-to-peak maximum excursion of 89 mm (3.5").

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.
