Thanks, Trevor. That could very well be actually because the trims are at +4 and +4.5. I will measure later. BTW, the SPL was scary. I thought I'd blow something up but I am sure the M100s can take a lot more. Also the feeling it evokes is worse than an amp self-protecting. Like something out of Inception or Dr. Strange where the room is folding in on you!
