I'm using Inguz to correct my Orions in my (pretty much untreated)
living room.  My experience so far is that I get the best results if I
only touch the bass, and only by attenuating it (no boost).  For
WAF/MAF reasons I need to keep the speakers too close to the wall much
of the time, and it's particularly helpful in reducing the giant bass
peak that causes.

Modes get very closely spaced at high frequencies (on a log scale,
which is how we hear), and the distance between nulls and peaks becomes
less than the distance between your ears.  So I'm also not convinced
that DRC is a good idea at high frequencies.

I'd like to know how to do that as well.
