The JBL STX828S is a dual 18" high power subwoofer system in a front-loaded, vented enclosure designed for maximum low-frequency performance.

Description
The STX828S is a high power subwoofer system containing two 2242H patented Super Vented Gap Cooled™ 18" woofers in a frontloaded, 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. By relocating an internal connector, it is also possible to drive each woofer discretely from a separate amplifier channel.
 
The enclosure is constructed of top quality birch/poplar laminate plywood and coated in JBL’s rugged DuraFlex™ finish. Each woofer is housed in an isolated chamber and the enclosure is heavily braced to maximize lowfrequency 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.

Features
  • Premium passive loudspeaker system
  • Very high power handling
  • Dual 18 inch, 2242H Super Vented Gap Cooled™ woofers for extended low-frequency output and extremely low distortion
