Get to know this product.

The SXC420, small-format loudspeakers feature a coaxially mounted 0.75” aluminum dome tweeter design over a proprietary high-excursion 4” woofer. The SXC line was inspired by the successful QXC in-ceiling speakers, and intended for smaller spaces like kitchens, bathrooms and hallways where a James SA Series speaker is not needed. These speakers are enhanced when paired with a James subwoofer such as the QXC10S or QXC8S.

All woofers are James designed with aluminum cones and Santoprene surrounds to allow marine use while maintaining the highest quality sound. All enclosures are constructed with aircraft grade 5052 aluminum and include white paintable aluminum grilles.

Installation could not be easier for either retro-fit or new construction projects. The SXC and the QXC series loudspeakers use a unique 3-piece installation method employing a lightweight frame, independent speaker body and a border-less aluminum grille that protrudes less than 3/16” (5 mm) - or completely flush with the addition of a pre-construction board.

Choose from a square or round grille (both sold separately).
