Out of curiosity, are you M80s set to full-range (large) or with a cross-over (small)?
Large.
Also, yes I realize a lot of people wouldn't put up with any sort of irregularities what-so-ever. And that is totally understandable in my book. However I give things a fair chance before jumping the gun. I know not many people would put up with a $2300 dollar subwoofer that had a single problem what-so-ever, however I am currently waiting on the THIRD replacement part to make this thing work properly. Guess I'm just patient.
