Designed as a dedicated midrange driver for application in door panel or dashboard installations, the GB40 is optimized for an infinite baffle application or an enclosure of at least 1 liter. The GB40’s 41 mm mounting depth makes it an easy fit in locations that require a shallow midrange. Like all the GB Series midrange speakers, the GB40 includes a grille and installation kit that can be customized to blend with or highlight nearly any installation.
