i have 2 klipsch r24f towers and they sound good but Just don't have the bottom end. Could you guys please recommend me a sub on a $200 budget please.
Sure. If it's a larger room and you have the space for it, get the
Dayton SUB-1500. If you don't have space for a 15, then get the
BIC V1220.
Here's a graph showing both of those subs topping the list for CEA-2010 test output among <$250 subwoofers (measured by Brent Butterworth, a well-respected reviewer). Both are on sale for less than $200 right now. The
Monoprice 9723 is third on that list, and less expensive than either of the first two at less than $150 shipped. (You could also get the 9723 from Monoprice.com, but
reports of potential quality control issues make it a good idea to have Amazon's generous return procedures available should you need them.)
