thanks bob, I am still trying to figure out what is the best setting for the speakers, I don't think my Receiver HTR-5590 allows me to set up my speakers individually, I am able to select (large, small, subwoofer yes or no, or main or both) but other than that nothing else, I can't change the Hz so right now everything is set at 79Hz, I don't know if this is good or bad, still trying to understand what exactly I am doing, I love the way the speakers sound. thank you for anyone with some help.
