CES VW-8820D 8″ DVC Woofer 8+8 Ohm
Overview:
The CES VW-8820D 8″ DVC Woofer is a robust, long-throw woofer that can be used in countless applications. A treated paper cone, thick, convex dust cap and foam surround combine to produce a stiff and light weight diaphragm. A large ferrite motor and sturdy 1.5″ diameter 4-layer voice coil mean this woofer can handle ample power and move a lot of air. Dual 8 ohm coils can be wired in parallel for a 4 ohm load, series for a 16 ohm load, or separately for two 8 ohm loads, making this woofer very versatile. A thick foam gasket allows this to be front or rear mounted in your choice of sealed, vented or IB applications.
