Have had this sub for about a year now, absolutely blew me out of the water after setting it up and trying my music on it. I recommend this for any music enthusiasts wanting to get that extra lower end kick in their system. 10/10 must have. Set up is as easy as plugging and playing. Can feel and hear it from the other end of the house!!
