Dual voice coil 200-watt sub-woofer was designed to use the energy from both the left and right channels simultaneously. Double the power – Double the bass energy. Used primarily for music, its designed to be installed into home or car audio. It features a rigid black powder coated cast aluminum basket.  The cone is treated engineered pulp cones with a polyether foam surround (the kind that lasts!). Heavy duty tinsel connects the voice coil to the terminal and it is stitched into the poly-cotton spider to reduce lead fatigue and failure. The woofer comes with a decorative rubber trim ring which also aids in sealing the speaker to its enclosure.  The wet look treat over the cone both protects is from moisture both also gives extra shine!
