The C Series 2-Way Component Speaker System is the perfect balance of high-fidelity refinement and value. Mid-Woofer: The 6.5-in mid-woofer features a cast aluminum frame and an aluminum cone coupled with a soft rubber dustcap and surround. This combination results in an acoustically well-balanced speaker that offers superb frequency response while exhibiting warm tonal characteristics.  Additionally, for reduced inductance, extended high-frequency roll-off, and increased efficiency the voice coils feature a double slit former and the motor utilizes a copper pole cap. Tweeter: The CT28 cloth dome tweeter offers a wide/smooth frequency response.  It features an attractive flush mount vented back machined aluminum housing. Crossover: The crossover networks are built with premium components, including Mylar capacitors and segmented air-core inductors. Selectable tweeter levels are provided for fine high-frequency tuning.
