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.
SUPPORT WITH EASE
All full range models in the GPL series are supported with EASE .gll files.
