I seem to have something wonky going on in regards to the auto calibration.

During auto calibration it detects my Left and Right BACK Surrounds at very different distances:

LBS @ 13'
RBS @ 2'

This is consistent each time through.

As far as position from the sweet spot both are the same height and distance behind and out to the sides.

The same for my LS being a little further out due to room size. Yet for the Surrounds (L/R sides) it nails them @ 7' (LS) and 6' (RS) out from the sweet spot; dead on.

I've set the delay to match the compensation for the surrounds, bringing the LSB to 12'.

I have yet to SPL to see how accurate the Auto Set-Up is.
