What I wanted to know is where do I set the crossover point on my subwoofer to match the best sound to my JBL HLS610 speakers. The sub has knob that controls the frequency from 50hz to 200hz. The speakers are from 55hz to 20kHz +/- 3db. My receiver is a Onkyo TX-8050 2 channel receiver. My receiver doesn't have a sub control so I have to adjust the crossover on my sub. I assumed to set it around 60hz on my sub but I don't know what is the best frequency for the sub.
