The 8340A Cinema Surround Speaker offers very high power handling, high sensitivity, and extended bass response in a very compact enclosure. The two way 8340A's proven reliability and performance features have positioned it as the industry standard for the extended dynamic range required by digital sound formats.

The 8340A features a high power, long-throw 250 mm (10 in) low frequency driver for smooth, extended bass response. The high frequency section combines a 25 mm (1 in) coil diameter titanium diaphragm compression driver with a constant coverage horn for very high output capability and wide, even high frequency coverage. The 250 watt continuous power rating (1000 wattpeak) provides extended dynamic range required for digital sound tracks with absolute reliability. Its modern, molded black textured enclosure with black grille enhances any decor.

JBL's QuickMount bracket allows one person to quickly and simply mount the very lightweight enclosure on a previously installed bracket half.

Built to traditional JBL quality standards, the 8340A will stand up tolong-term use under adverse conditions while delivering excellent performance.
