What causes farting out? When I say Farting Out I mean that the notes start to sound alike and the overall sound is not clear. Like F and F# sound the same. Of course this goes away when I lower the volume. Is it a fault of the Speaker being pushed too hard? I notice it more on the Schroeder Mini12 then on the EpiPS112. Would it go away at high volumes if I add a 210 epi. I used the 2 12's together but It was still somewhat noticeable and the Shroeder sounds so much more nasily in comparison.
