The Sonance Blaze Audio C12S is a shallow passive subwoofer that delivers solid output from a discreet form factor — engineered for medium-SPL applications where strong low frequency performance has to coexist with sleek modern interiors. The MDF cabinet houses an advanced 12-inch woofer with a high-efficiency motor and a carbon-fiber-reinforced cone for accuracy under sustained output.

A 75 mm voice coil built on a high-strength fiberglass former with windings on both the outer and inner coil surfaces delivers balanced drive and very low distortion, while chassis cooling channels reduce power compression and improve dynamic response. The cabinet can hang on the wall or stand on the floor with drivers protected from accidental contact. Screw-terminal connections accept up to 4 mm² conductor and route through the cabinet rear into the front baffle, keeping speaker wiring clean and invisible. The black finish complements modern commercial interiors and pairs with the Sonance Ci-series loudspeakers.

The 12-inch driver lets the C12S handle larger spaces and higher SPL levels than the C8S can support. Specify one C12S per pair of Ci-series satellites for background music; double the subwoofer count for foreground music and dance-floor reproduction.
