Hi, BigguyinATL,

Thanks for the reply. I'm not sure what you mean by the sum amplifier. Is that the power amp or the plate amp in the subwoofers?

The subwoofers don't "thump" when connected to my integrated amp or with other preamp/amplifier combinations I've tried. It's specific to the Prologue Premium/M22 combination.

I have contacted the manufacturers and am waiting for a response to see if they know what is causing the DC offset and if there's a fix.

I'm not that concerned about the subwoofer drivers but am wondering what the DC discharge might be doing to the built-in DSP circuitry.

Regards,
Tom
