Ok, I know this is going to raise some hairs, but I have just gotta ask. If I am looking for flat response speakers, for reference purposes, why can't I use a clean eq (after the mixer, but before the power amp) to compensate for poor speakers. For instance, if I have a pair that hypes the bass, or the midrange, why can't i just cut that with an eq after my mixer, but before my power amp. Or use a power amp with a built in EQ? After I have referenced my monitors to a truly flat pair, or after checking a mix on several systems, I ought to be able to get it to a balanced response, then I would just lock down the EQ settings, and never touch them again.
