This is the Velodyne Impact 10" woofer. Its powered by 150 watt RMS amplifier with front firing woofer and down facing port. It has a nice and compact footprint and is place in a room for music or movies. It Retails for about $650 and is in good shape and rady to be used. I upgraded to another Velodyne subwoofer better suite for my needs so i don't use this one anymore. Email to arrange pickup. Thanks for looking
