Overview

​

Designed as a dedicated midrange driver for special applications in 3-way systems, the GB25 is optimized for enclosures as small as 0.2 liters (2-1/2” x 2-1/2” x 2”).

 

The GB25 can be installed in a tiny enclosure in a custom A-pillar or used infinite baffle in a door panel or a dashboard.

 

Like all the GB Series midrange speakers, the GB25 includes a grille and installation kit that can be customized to blend with or highlight nearly any installation.
