hey guys, I have a room that is 10 feet wide 17 long and 8 foot high ceilings. I have some poke RTI6 bookshelf speakers that put out a pretty good amount of base, basically I'm just looking for something to give my system just a little bit more punch nothing too crazy. What I do want to do though, is run dual subwoofers either 2 10 inch subs or 2 8 inch subs. I mostly listen to music and TV 90% of the time and my budget is around 500 bucks for both. Any thoughts or recommendations would be greatly appreciated thanks.
