ตู้ลำโพง ยี่ห้อ JBL รุ่น VPX718S

VPX718S uses an 18” (457mm) JBL 2044G woofer in a front vented enclosure to reproduce low bands with extended frequency response and low distortion, and to stand continuous power up to 500Watts.

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.

VPX718S is equipped with a 35 mm socket for installation of a full range satellite speaker weighting up to 50 kg (110 lbs). Two handles are provided for easy transit and set-up of the subwoofer. 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.
