How high up the frequency range do you apply room correction?

[jhaider]

With good speakers placed appropriately and using DLBC I've yet to find a material difference between full-range (with the target curve basically fit to the natural treble rolloff of the speakers at that listening distance) and limited bandwidth. So while I understand the theory that we should do limited bandwidth I'm not even sure which one ended up being my in-use version.

RoomPerfect and Neumann MA 1, which I also use, are full-range only.

I do full range with a Trinnov, but I trace the “before” measurement, including a dip at the mid/tweeter crossover point, like a line of best fit.

Higher than schroeder but not full range. (at least above 70db/1m levels, below that I use no eq at all).

I have room issues that go to 2kHz due to a very large and lively floor, and a complex floor structure that does some strange things as SPL builds. Since the floor sound is everywhere, I find eq works pretty well for me. If I went to 200, I would still have a huge dip at 400, boost at 800, and dip at 1200, and a large peak at 1800 (roughly speaking)... all from issues with my floor.

As a general rule, considering other rooms, I tend to go this route: EQ the bass to my target at 200 and below. Then, if something bothers me, I look at measurements to confirm, then fix it so it sounds good to me. I am frequency agnostic in this process.
