Today I tried this free systemwide eq for Mac. I liked the results how it affected. But the eq itself its crap, it distorts every once in a while. And can't use it when recording. I'm convinced now that I want to use corrective eq for my main speakers. Only negative effect I found it added some distortion around 60hz.
Any advice what would be good EQ for speakers? I'm thinking maybe a physical unit, so I could set it and forget, also feed only for my main speakers.
