This is a sub sat system featuring a pair of high and mid speakers with 3/4 tweeters and 3-1/2 inch mid drivers. The sub woofer features a vented 8 inch woofer with plenty of bass. The woofer was recently re-foamed with a rubber surround and has deep excursions. This is a very high quality speaker system, especially usable in areas where space is limited. It will satisfy the most discerning of music listeners. Please contact me with any questions. The speakers are connected to the subwoofer and the subwoofer is connected to the amplifier. Speaker wire is not included.
