Hi vp8000,check in the manuals for the klipsch for what the frequency response is[say 36hz to 20khz for the KLF20's for example] set the crossover to 60 hz or even 80, see what sounds best to you, in other words set the crossovers higher than your frequency responses, I have klipsch speakers also and that seems to work for me. Have fun.
