I have recently set up Onkyo 595 with Energy Take5.2 + S8.2 woofer. I connect the subwoofer output of onkyo to the input of sub. When doing a pink noise test using AVIA or amp's internal tone, nothing is heard from the sub. I have check all the settings on the amp and everything seems to be configured correctly. Then when I connect the amp's subwoofer out to the x-over input of the S8.2, I can heard the pink noise tone on the sub using the amp's internal tone. Is there something wrong with the subwoofer? For those who have the simimlar setup, what is the speaker calibration levels on the onkyo amp and the settings of BL and x-over on the sub? Thanks.
