I'm buying a house with the following home theater area in the basement:



I'm going to replace the small HT-in-a-box Panasonic speakers with a set of Klipsch RB-25's front, RC-25 center, and RS-25 surrounds, running off my Denon AVR-1803 receiver and Denon DVD-2200 source. The RB-25's are front-ported, and can be either stand-mounted, wall-hung, or placed on a bracket held away from the wall.

Aesthetically, hanging the speakers on the wall (with some small rubber spacers behind them) would look the best in this room. But will I be losing anything acoustically by going this route? Will the bass be muddier or "boomier" with the speaker directly on the wall vs. on a bracket held away from the wall? (Speaker stands are out due to the wife factor and toddler factor.)
