To get rid of it, it is best to engage the amp's lowpass filter, at about 20-30 Hz above the the MS-8 crossover frequency. So, if you have the underseats/fronts crossed at 200Hz, set the filter to 220 - 230Hz. This way, the level will be set correctly and the MS-8 autotune can function correctly. If you don't have the option of lowpassing the signal, set the gains about 5dB louder than the other speakers.
I'll try this as well and see what happens.
