The direct modes are a marketing feature they feel obligated to throw in, however in truth, they should never be used, unless you purchase an outboard microphone calibration system which trumps Audyssey XT.
The outcome was worse than before, really tinny sounding with no body to the sound at all.
I went into manual set up and reset the speaker distances using a measuring tape (Audyssey set the sub about 10 ft too far away) and reset the crossover frequencies based upon my prior knowledge of the speakers' behavior and where I have the sub's crossover knob set
Audyssey's selection of x-over frequency is based on actual in-room measurements, which trump your "prior knowledge" even if it's based on test reports done by a multi-million dollar speaker testing facility. Your room and exact speaker placement is what's being corrected, not so much the speaker itself. Speakers which claim to go down to , say, 30 Hz may not
in many rooms. Trust Audyssey instead of bypassing its computer controlled decisions.
The sub distance discrepancy may be due to a slight latency in the sub's output due to it's electronic circuitry (or other reasons). Use the subs direct mode and don't override what the receiver measures the EFFECTIVE distance as being, which takes any electrical delay/room conditions into account which you can't measure.
Use the sub's "direct" or "bypass x-over" mode and let the receiver have complete control. If you have one of the very rare subs without a direct mode, peg the sub's frequency to the highest setting and the receiver will select a setting below that.
Also be sure the receiver considers the speakers as "small", regardless of whatever you
think they are. "Small" really means "allow the sub to work properly (bass management)" but was a stupid wording when they designed these things a long time ago.Edited by m. zillch - 1/8/13 at 11:11pm
