Audiofrog designed the GS40 4" woofer to deliver the midrange details in a custom component system. A responsive polypropylene cone provides high internal damping for smoother frequency response, and Audiofrog uses a 1" copper voice coil to enhance power handling.

Creative installation

Audiofrog was founded by experienced installers, who know all the pitfalls and shortcuts of custom installations. With the included mounting hardware, you'll find custom fabrication of a speaker location much easier. The GS40's removable ring can be painted or upholstered, depending on your vision for your interior. The grilles are ideal for painting as well.
