Perhaps stupid questions but:
In AustinJerry's guide where it discusses gain matching... I assume this is done with the AVR/Pre-Pro test tones with volume set at reference, so that both subs together achieve 75db at listening position? The Marantz I'm using plays those tones based on what the current volume is set to, which is why I am asking.
Also, though this Marantz has XT32/Sub EQ, I have had no luck with it working correctly (seems to have issues with delays, causing cancellation until distance tweaks are applied). Should I just pick up 4-way Advanced and run both subs off single input channel? My assumption is if Audyssey is trying to EQ the bad (pre distance tweak) output, then it is getting the EQ wrong...trying to adjust for nulls that aren't there after tweaking is completed, possibly making overall EQ worse.
