All:

I have been searching for definitive answers to this common question, but I haven't been able to find an evidence-based thread to answer, so any help would be greating appreciated.

I'm resetting up my home theater after a flood and need to enter the subwoofer distance into the receiver to allow it to set the appropriate signal delay. I have 2 identical subwoofers that are equidistant from the preferred seating area.

Should I:

1. Enter the exact distance as measured by a tape measure

2. Measure the exact distance with a tape measure and enter it into an equation for a corrected distance (I seem to recall there is a formula you can plug the exact distance into to get a corrected distance)

3. Use my receiver's autosetup (YPAO) program to measure the acoustic distance.

If the answer to #3 is "Yes", should I trust this program to set up the distances to my other speakers as well? (they are off from the measured distance by a few inches)

Thanks in advance for your help!
