Hi, Just moved into my new place and ran the auto callibration on my Pioneer Ax5 amp. As per usual it thinks my subwoofer is about twice the distance from the listening position than it actually is. It consistently gives the distance around 6m where it's probably just over 3. Every other speaker is pretty much bang on. The question I have is that should I correct the sub distance on the setup screen? I'm thinking that it's a rear firing sub and if the microphone senses it as being 6 metres then maybe I should leave it at that. Is the sub performance or the acoustic setup of my room such that the sub must be set at a greater distance to compensate? Or is the sensing microphone just really crap at judging subwoofer distances meaning that I should correct it asap? Thanks in advance.
