| Re: What`s next 20x20 is a fairly large room. Assuming 8' ceilings it would be about 3200 ft³. The 10 inch sub would probably be on the small side, but given that you are using smaller speakers in the surround bar it might be ok. I'd go with one of their twelves. For an extra $100 you'll get a whole lot more performance.
A subwoofer will make an enormous improvement seeing that the surround bar's are very weak on the low end. Note that you would also want to set the crossover on you Denon higher than the recommended 80Hz standard.
How does the bar sound anyway? I've seen some in stores but it's hard to get a feel for the surround capabilities. |
