Wharfedale Pro GPL-218B Passive Subwoofer
GPL-218B is a dual 18″ bass-reflex subwoofer from our GPL Series, engineered to deliver extreme low-frequency power and precision for large-scale fixed installations and performance venues.
Featuring two Beyma 18″ LF drivers with 4.0″ voice coils, GPL-218B provides immense output capability with exceptional control and thermal stability. Its dual-chamber bass-reflex design extends low-frequency response while maintaining punch and definition, ensuring powerful, distortion-free bass even at the highest output levels.
Built from birch plywood and finished in durable black or white Tough-Tone paint, GPL-218B combines strength, efficiency, and visual versatility. Professional 4 pole speaker connectors and barrier strip connectors allow secure integration into high-performance sound systems.
Delivering 2000 W continuous (8000 W peak) power and achieving 148 dB max SPL at 1 m, GPL-218B forms the ultimate foundation for GPL full-range loudspeakers. FIR preset libraries and EASE .gll files are available to ensure perfect system alignment and predictable performance in any installation.
