I have a HK AVR525 and I want to set up the individual crossover rates for all my channels. Currently I have the RTI38's as my Front L/R. In the booklet that came with the speakers it says the crossover is 2.2k but isn't that way high. The AVR525 booklet says to set the crossover at the frequency that the speaker switches from mid's to low's. Currently I have that at 100hz. Is that correct or should I go lower or higher?
