The EQ settings I'm currently using in the Crown amp DSP are as follows:

24Hz  +9dB      27Hz  -9dB      40Hz  -11dB      45Hz  +4dB      58Hz  +15dB      73Hz  -10dB      88Hz  +11dB      99Hz  -3dB

It seems to me some of these adjustments are rather large, but what do I know?  

I’m new, comin’ to this party late but...

I think someone covered this but 15dB boost @ 58hz suggests a room mode - sound waves canceling each other at the mic’s pick up place

Anytime time I see boost more than 3-4dB I get concerned especially below 50* hz. Many years ago someone said or wrote using EQ: “think of yourself as a wood or stone carver - remove what you don’t want - the peaks.” W/that mindset you will very slow to boost at any frequency.
*as frequency falls, when boosting, power demands increase 3-5 fold YMMV

thanks for reading this far, hope this helps.

My first post on this website. I’m struggling to connect the two previous replies w/all that came before. 

and...

Infrasonic opened a question on surround back speaker positioning that I’d like to ask here if that’s ok. Otherwise please suggest which forum page to post upon. Either way I’ll follow w/my system details in a separate reply.
