Anyone have anything good or bad to say about this sub? My brother is moving and wanted to know if I wanted it. Of course I will take a free sub, its new and like I said... free. But, I wanted to see if anyone had any warnings or praises about it. Of course, any information is greatly appreciated and thanks in advance.
