The only way to really know what 125 and 440 and 3k is doing -- like any musical instrument -- is practice. So whether you have a home theater, a disco floor, a pristine 2-channel pair of whatever; the trick is to take the controlling device, sit in the sweet spot, and learn.
One time (and Carl from JL was in on this job...) we had to put in a tiered system in a jazz club. There was a stage area, a hallway, another bar area, and a restaurant. The real idea was to time the system so that when you were in each area, the piano from the stage (which was itself a piano bar) was correct in each of the other areas, each about 40+ feet further away.
The look of amazement when he club owner first heard this was priceless! First he said "it isn't on!" then I turned it off. Then he said, "It sounds like a piano!" He had been so used to hearing a crappy speaker representing a piano that when it was all timed out (and gently eq'd) it sounded PERCEPTUALLY REAL and correct for the space you were sitting in!
My suggestion is to find some old digital delay and a 27or 31 band graphic on ebay or someplace, connect 'em in series (the DDL first, BTW) and connect that from a Y connector from your SUB OUT (or a REAL LFE OUT if you have one) ; into the amp for the controller; and then of course while you are sitting in the chair in question, start messing with the controls.
Once you get the delay parameters and response correct for that particular situation it should sound /feel superb.
Of course if your sub was good enough and properly set up in the first place you wouldn't really NEED the physical device, but hey, all this stuff sure is fun.
And here's another hint. When I had my store setup I went to a furniture store and somehow convinced the fellow to let me try about 9 different leather chairs. I told him I was going to buy a FEW, but I judt didn't know WHICH ones. The differences in bass response while sitting in the chairs was incredible. As it turned out I had the sub about 3 feet from the sweet spot, and I swapped the chairs around. Some of them swamped up the bass like a sponge. The one I wound up keeping seemed to make the bass even clearer, perhaps because it might have been soaking up the subsonic while leaving the important 32-70 alone.
Here...is this better.
