GPL SERIES
GENERAL PURPOSE LOUDSPEAKERS
GPL-28B
BIRCH PLYWOOD
All GPL models use premium Baltic birch plywood construction.
Not only does this create a solid and durable cabinet, but it also contributes to the overall sound and character.
GPL is also covered in our most durable and hard wearing Rhino Rock paint finish. This ensures that a GPL loudspeaker will always look as good as the day you installed it.
INSTALLATION HARDWARE
Installations can be complicated enough, so Wharfedale Pro have made GPL series as easy as possible.
GPL-5 and GPL-8 are quickly fixed to a wall using the WPB-3 wall bracket or the included steel yoke. GPL-12, GPL-12HQ, GPL-15 and GPL-15HQ are quickly fixed to a wall using the WPB-1 wall bracket or the included steel yoke.
These models are also compatible with Powerdrive Series 100 or Omnimount Series 60 installation brackets.
SYSTEM SOLUTIONS

GPL is engineered for any scale of system. Live or install, there is a GPL solution.
The system in the diagram uses our Wharfedale Pro DP series amplifiers with downloadable presets for DP-N and DP-F models.
