Sorry to contradict, but you need to do the exact opposite!
- First calibrate your subwoofer with the antimode.
- Then run the MCACC, while leaving the antimode on.
Consider that, when using the antimode first, you create something that will be seen by the amplifier, as a (nearly) perfect subwoofer for you room.
Therefore, the MCACC will have nearly nothing to do on the subwoofer channel, except correct its level.
If you reverse this order:
- The output level on the sub will be completely wrong.
- The distance for the subwoofer will be wrong, as the antimode internal processing induces a delay, equivalent to an additionnal 90 cm (about 3 ft).
I have always proceeded as I just explained, and it works fine, with a subwoofer (XTZ 99W12.18ICE) that blends in perfectly with my other speakers, down to around 20 Hz.
