FEATURES
What the VPX728S brings.
VPX728S is a dual 18-inch high-power subwoofer for live music, speech and pre-recorded playback, made to pair with full-range satellite speakers. Two 18-inch (457 mm) JBL 2044H woofers in a front-ported enclosure reproduce deep, low-distortion bass and handle up to 1000 W continuous. Stood vertically, a full-range speaker can be stacked directly on top without a pole.
A pair of Neutrik® Speakon® NL-4 connectors suits different wiring schemes: the woofers ship on pins +1/-1 and can be switched internally to +2/-2. Two handles make it easy to move and install. The braced plywood enclosure is finished in rugged DuraFlex™ coating, and the CNC-machined 16-gauge steel grille is backed with acoustically transparent fabric.
