I have an H/K AVR130 and I am trying to figure out the crossover settings. Everything is set to 100hz as a default. I have Polk R30 fronts, a CSI3 center, R15 rears and a Dayton Sub ($99 one). I tried to post links to the specs for the speakers but I have too few posts to be allowed to. I am new to Home Theater - as you can tell by my system - and have found this site unbelievably informative. I have tried the search feature to no avail. Please help figure out how to find the information I need from the speaker specs or direct me to a resource that can. Thanks.
