I've decided I'm going to purchase some reasonably priced towers, and a center to match, hopefully to help eliminate some of the frequency gap that occurs when using a small sub/sat system. I haven't totally decided on what speakers I'm going to get, either klipsch or BIC America (basically something horn loaded), since I'll move my current Klipsch satillites around to the back. One thing I was wondering though.. Since the front speakers will have a lower reach frequency and I'll be able to set the crossover lower, will that greatly comprimise the sound I get from the surrounds since they can't go quite as low?
