Hi guys -
I was making some adjustments to my miniDSP after moving one of my subwoofers and ran into some unexpected results with REW. Here's what I did:
I setup REW with a timing reference (using the center speaker) and ran a frequency sweep
I then ran sweeps with the same center speaker as a timing reference for the front and rear subwoofers, intending to use the delay differences in my miniDSP setup.
Oddly - my initial sweep went wrong somehow: showing a delay of 7.5ms for the center speaker using the center speaker as a timing reference. That obviously doesn't make any sense. Any insight as to why this happened? I re-ran the test with the sweep running from 80Hz to 300hz (eliminating the subs) and ensured my receiver was set to pass the signal directly through.
