The GC8S is a passive in-wall subwoofer designed to enhance low-frequency performance in both residential and commercial environments. Featuring an 8" woofer, it delivers deep and controlled bass while maintaining a discreet and compact form factor.

An integrated passive low-pass filter allows the GC8S to be connected on the same line as GC or GF satellite speakers, without the need for DSP or a dedicated amplifier channel. This simplifies system setup and reduces installation complexity.

Its open-back design makes it ideal for mounting in drywall, wood, or similar surfaces, easily adapting to complex spaces such as home theaters, hotels, wellness centers, retail stores, or public venues.

The frameless magnetic grille, available in round (GC8S-RD) or square (GC8S-SQ) shape and in white or black finish, is paintable to blend seamlessly into any architectural style.

Fully compatible with all KGEAR amplifiers, including GA201, GA41/41L, GA43/43L, and GA46/46L, the GC8S offers a coherent and complete solution for high-performance flush-mount audio systems.
