Can anybody tell me the correct setting for a subwoofer on the Pioneer Ax5i-G? I have an REL Q150E Mk II connected on high & low settings. When doing the automatic speaker callibration the subwoofer is set at -10db. The other speakers are set at 10db. I have manually set the sub at 5db with the volume control on the sub at about 1/4. This gives me the best sound when watching movies. Should I be setting this higher? or should i put it back to -10db and crank up the sub volume? any suggestions greatly appreciated.
