Hi Gonk, just a question, I tried what you suggested to chipvideo setting the crossover to 80 to get the sms-1's test tone than I set it back to 60 where I had it, and the response curve is all messed up.To make a long story short after I downloaded the new firmware I figured I would recalabrate and play around.should I just calabrate at 60 and be done with it or 80 and then back to 60? Thanks Loopy
