GPL-15HQ
15" coaxial with Constant Directivity waveguide
GPL-15HQ is a 15″ full-range loudspeaker from our GPL Series, designed to deliver powerful, high-precision sound for theatres, clubs, and performance spaces.
Equipped with a Beyma coaxial driver featuring a 4.0″ LF voice coil, GPL-15HQ offers exceptional detail and dynamic response. Its 80° x 40° rotatable constant directivity waveguide provides accurate, controlled dispersion, allowing precise HF targeting and reduced reflections in complex acoustic environments.
Built from birch plywood and available in black or white, GPL-15HQ combines premium build quality with flexible installation options. A steel yoke bracket is included for quick mounting, and GPL-15HQ is compatible with optional WPB wall brackets, Powerdrive Series 100, and Omnimount Series 60 ensures maximum versatility for permanent installations.
Handling 500 W continuous (2000 W peak) power and achieving 132 dB max SPL at 1 m, GPL-15HQ delivers refined, high-output sound with impressive consistency. FIR preset libraries and EASE .gll files are available for precise integration into professional audio systems.
