More Information

Powered by an 18″ LF driver with a 4.0″ voice coil, GPL-118B combines power and precision, producing tight, controlled bass with excellent transient response. Its finely tuned bass-reflex enclosure enhances low-end output while maintaining clarity and definition, making it ideal for theatres, clubs, and live venues demanding impactful yet refined low-frequency reproduction.

Constructed from birch plywood and finished in durable black or white Tough-Tone paint, GPL-118B integrates seamlessly into fixed installations. 4 pole speaker connectors and barrier strip connectors provide secure, flexible connectivity options for professional audio systems.

Handling 1000 W continuous (4000 W peak) power and achieving 140 dB max SPL at 1 m, GPL-118B delivers deep, powerful performance with the reliability expected from Wharfedale Pro. FIR preset libraries and EASE .gll files are available for accurate system configuration with GPL full-range loudspeakers.
