I followed the directions from minidsp for
speaker time alignment. I plugged into my laptop into the TV (Sony Bravia) with HDMI.
I did confirm that the Denon will not accept any speaker delta greater than 20' (6m). You can make all your distances large, but no more than 20'/6m difference between them.
Measurement | FL | FR | SL | SR |
Actual (feet) | 8.5' | 9.3' | 4.6' | 3.9' |
Audyssey setup (feet) | 9.0' | 9.0' | 28.2' | 28.2' |
Measured delay (msec) | (reference) | 0.45 msec (6.1") | -23.35 msec (-26' 3") | -23.36 msec (-26' 3") |
Using the FL as the reference, the FR measured 0.45s slow (6.4"), which would mean its further away than expected. This might be because I put the UMIK-2 slightly off center (which the 8.5' vs 9.3' would vouch for).
The -23 msec delta for the SL and SR means the speakers are closer than expected and I need to reduce the 28.2' distance. If I change the distance to 4.2', I get a delay of 0.68 and 0.66 msec (SL/SR respectively). I could have tweaked it a bit more, to maybe 4.3' or 4.4', but didn't take the time. Those are basically the actual distances.
This confuses me. I don't know why the SL and SR would be at their natural distances if the SVS Tri-path is adding about 19 msec of delay.
I've attached the measurement data. The FL and FR and SL all have the subs turned on. The other measurements do not. I think a few things have changed since I last ran Audyssey, so the rears are a bit loud and I have a bad drop out on the FL around 110-160 Hz that I need to debug.
I did try some listening tests, but I could not find something with, for example, someone talking in fronts and someone else talking in rears, so do not feel confident based just on music and effects to say one way or another.
I will keep plugging away at this, I don't like not understanding the measurements versus Audyssey distances and SoundPath delay.
