Before spending four figures on digital room correction hardware, I would suggest trying a software program to optimize loudspeaker placement.
I would guess there a re several of these avalable, but one I have used is a $99.99 program called "Room Optimizer" available from the PRG Difussor folks (I believe they're one of the major manufacturers of room treatment products) available at: http://www.rpginc.com/products/roomoptimizer/index.htm.
I have used this program with great success to smooth out "lumpy" bass in my listning room which was obvious to my ears despite multiple ASC Tube Traps and endless "trial and error" repositionaing of speakers not quite getting it done.
To use this very simple program one merely enters the room dimensions (L, W, H), a little info on low-frequency driver position - i.e. height from floor, or "Z" axis (assigning one driver as the "independednt" driver and the others as dependednt on the first driver's position), an acceptable range for the listening position, then clicks on "start" and the program - through repeated "virtual" repositioning of speakers - comes up with the ideal position for the smoothest possible bass. You can even enter parameters for the position of the speakers to fall into in order to keep the speaker position within some reasonable placement range for aesthetic concerns. It will then give you the placement coordinates and show a graph of best and worst frequency responses for the possible speaker placement coordinates that fall within your defiined parameters.
In my case and for my room, I learned that in the wrong position I could have peaks and nulls of over 20dB difference! The results in my case were amazing...not a subtle thing.
I've read over the past several years about sophisticated hardware, most notably the TacT - which I'm sure can be extrememly effective for room correction - but have not heard any such equipment. In my case and at present time, using this program to reposition my loudspeakers I am not hearing amything that makes me feel I need to spend this kind of money for room correction hardware.
FYI: I have no connection/affiliation with PRG or this software other than being a satisfied user...
