Parametric EQ for Mid-bass Hump?

I was planning on replacing my speakers (PSB Image 7PT), but have recently been considering a parametric EQ treatment to cure the mid-bass hump and add a little presence in the treble. Bass problems come from an HT type speaker placement (essentially built into a wall of bookcases) and an 8’ ceiling/16’ wall standing wave issue. My room is also fairly dead and I think this is sucking a lot of presence out of the treble. I like my comfy sofa, drapes and oriental rugs and would like to try an electronic solution versus major room surgery. Looking at a pair of Rane PE 15 equalizers, $300 each new, in the monitor loop of my Musical Fidelity 3.2 integrated. Any thoughts? (I am trying to do a poor-man’s version of the Rives PARC system.)
