JBL STX818S SINGLE 18" BASS REFLEX SUBWOOFER
ตู้ลำโพงซับเบส 18"x1
OVERVIEW
A single 18" compact high power subwoofer system in a front-loaded, vented enclosure designed for minimum frontal area provides 1,000 watts of continuous pink noise power handling, 2 kW program and 4 kW peak. The STX818S also comes equipped with a top-mounted M20 pole-mount and an optional wheel kit.
The STX818S is a compact, high power subwoofer system containing a 2242H patented Super Vented Gap Cooled™ 18" woofer in a front-loaded, vented enclosure. The enclosure is designed to present a minimum frontal area. The system offers complete input connection flexibility for compatibility with a variety of cabling schemes. A recessed, external switch allows selection of either contacts +1/-1 or +2/-2.
The STX818S is equipped with a top-mounted, threaded, 20 mm socket that can receive the optional SS4-BK pole. This adjustable height pole can be used to mount speakers equipped with standard 35 mm pole sockets and weighing up to 50 kg (100 lb). The threaded socket minimizes buzzing and rattling and assures that the pole will be secure and straight.
The enclosure is constructed of top quality birch/poplar laminate plywood, coated in JBL’s rugged DuraFlex™ finish and is heavily braced to maximize low-frequency performance. The attractive CNC-machined, 14- gauge steel grille is internally lined with acoustically transparent cloth to provide additional driver protection and give a very professional appearance. The rear of the enclosure is fitted with T-nuts which may be used to attach the optional WK-4 caster kit.
