Hello Mr Swedien,
thank you for your many many good informations.
i saw, that you use the westlake monitors.
i use also these very very good speakers, but sometimes i have problems
in some frequencies.
some mixes have too much bass ( about 2 db at 80-150 hz ) less mids ( about 2 db at 500 hz and 800- 2000 hz ( depends on song and studio)) too much at 3 or 5khz ( depends on song and studio))
my experience is, these speakers are very sensitive for studio acustics (room resonances).
are you using a subwoofer with the westlakes. why do you have the tweeter
