I've got a JBL 10 inch downfiring sub. It's a couple of years old and I'd like to move up to the above sub. Its selling at the local A&B Sound for $777 CAN. The guy said th price is guaranteed so that I could get some money back after the inevitable Christmas sale. How is this sub? I'd like to get deeper bass with my movies. Will this do it? It has a remote, which would allow me to tweak it easily. My other six speakers are Missions.
