Thanks.Green is the new measurement. My EQ only allows 63 - 125 - 250 - 500 - 1k - 2k - 4k - 8k - 16k
I could see a bump up at 125, 250, 4k... after that, it's sub placement and room treatments, right? Phase for the sub... always scares me to think about how to figure that switch out on the sub. It's at the standard 0, always wonder if I should ever switch it to 180.

Compared to the peaks and dips you might wanna fix, your Marantz EQ is too coarse. However this doesn't mean it's useless. Considering common house curves like Harman or B&K there may be some room for optimizations you could use your EQ for.
I have attached a .REQ file representing your graphical EQ as a parametric one. The Q values are an educated guess of one octave. With measurements you should be able to verify these at one point.
You can open it in REW's EQ Filters window, and adjust the various Gain values to see what's achievable with your graphical EQ. Because you can ask REW to only optimize gains while leaving F and Q alone, you can even use it to let REW match a target curve as closely as it can. For instance taking into account the interactions between adjacent GEQ sliders.
Hope this helps!
