JBL VPX728S is a dual 18” high power subwoofer system designed for live music, speech and pre-recorded applications and for use with full-range satellite speakers.
VPX728S uses two 18” (457mm) JBL 2044H woofers in a front vented enclosure to reproduce low bands with extended frequency response and low distortion, and to stand continuous power up to 1000Watts. When placed in a standing position, a full range speaker can be stacked on its top without the need for an additional pole.
The subwoofer system offers compatibility with a variety of cabling schemes. A pair of Neutrik® Speakon® NL-4 connectors are provided and are shipped with pins +1/-1 connected to the woofer. To meet different cabling requirements, the woofer can also be re-configured to work through pins +2/-2.
VPX728S provides two handles for easy transit and set-up. Its enclosure is made from premium plywood, finished in rugged DuraFlex™ coating and braced to maximize low frequency performance. The CNC-machined 16-gauge steel grille is backed with acoustically transparent fabrics to provide additional driver protection and give a very professional appearance.”
