The only exception is for large bi-amped (or more) monitors where
they will not even be accurate w/o EQ. Then we spend a long
time, preferably with very sophisticated measurement and
analysis tools, and a good digital processor / x-over to get it
just right.
Never, ever use a graphic or even an analog parametric on
nearfield/midfield studio monitors. Fix the room, fix the
mounting system, lose the big wooden console, etc etc, but
analog EQ's sound awful compared to fixing the problems and
running your monitors without them.
Unless of course, some bonehead studio owner is waving lots of
money in your face and won't accept any other solution...

It's okay to EQ your room to fix speaker boundary interface problems, but
NOT to fix room mode problems.
If your speakers are too close to a wall, you might need a little cut on
the low end to compensate for the extended baffle that the wall makes....using
a shelf EQ here is fine, it's exacly what the acoustic compensation switches
on the backs of some active monitors are intended for.
Don't bother trying to EQ out peaks and valleys caused by room modes...they
are only solved by trapping and room dimension changes. Besides that, you
can only EQ the peaks, and can't do anything about the nulls.... best not
to try.
Cheers,
Kris

I suspect the peaks are due to boundary walls interference.
I didnt even think about the nulls not benefiting.
Yes if I use the 80hz roll off on the hr824s the problem goes away ofcourse
since the problem is at 47hz.
I have a 12db peak at 47hz and a null at 108hz only on the left speaker.
Thanks,
