I don't know about your receiver, but if available, the distances from each speaker should be measured and entered, for coherent sound. White (or pink) noise is greatly preferable to a tone for setting speaker levels. I think there are DVDs and/or CDs that have such noise, if your receiver doesn't generate it. The Radio Shack sound level meter is inexpensive and good, Use the C scale and slow setting. Hold the meter near your seating position, and a bit away from you so as not to create a major acoustic shadow. Set the output of all speakers equal. Don't forget the sub, if you have one.
