For those who value substance and great audio performance… C1 is the real deal at a very sweet price!

Benefiting from our expertise in building world-class subwoofer drivers, the woofers in C1 components and coaxials are engineered to get loud, while maintaining smooth, dynamic, low distortion sound. Each C1 woofer driver employs a purpose-built frame design, equipped with a DMA-optimized motor system, and mineral-filled, injection-molded, polypropylene cones. A rubber surround with advanced rear suspension designs and integrated lead wires ensure precise voice coil control for improved sound quality and enhanced reliability.

C1 speakers also use real aluminum dome tweeters with silk suspensions for refined high-frequency performance and improved response. Coaxial models are equipped with true, 2nd order high-pass filters on-board, for smooth, accurate treble reproduction and low distortion. Component systems include in-line, outboard 2nd order high-pass filters, with Advanced Tweeter Protection Circuitry. Surface and flush mount fixtures are also standard with C1 component tweeters.

To ensure good fit into most vehicles, we offer a wide range of C1 sizes, all with moderate depths and minimal tweeter protrusions, to install neatly in to most factory speaker locations, behind factory grilles.
