I don't know
very much about convolver. This is the most basic thing that it does, and I just stumbled across the capability in REW.
Most of the Digital Room Correction stuff is over my head. You can learn a lot about it just by doing a Goolge search for "digital room correction" but implementing it seems very, very complicated. I'm not a computer programmer either.
All I wanted was a parametric equalizer to use with Foobar2000. Every time I went looking for one I would read in a forum that you should use Convolver. That's easier said than done, for the unlearned like me. Installing Convolver is a cinch, but it needs a "suitable impulse response generated by a tool such as DRC." I couldn't figure out how to generate that impulse response. I had been using REW for my sub, but for months I did not realize that REW could make the impulse response for Convolver. I had been sitting on the answer!
A lot of the Digital Room Correction stuff is over my head, but thanks to John's REW the parametric equalization stuff is easily within reach.
I have read that an individual's ear will affect the way that they hear treble from an transducer located so close.
I also look at the HeadRoom measurements. I found them to be relatively useful for judging overall tone and evenness.
For example my HD650 has a very smooth treble response (for a headphone) and a bit of a mid bass hump.

But when I listen to the HD650, I hear a different shape than I would expect from the HeadRoom graph.
Here are my filters inverted, which approximates what the uncorrected HD650 sounds like to me.

Not entirely dissimilar, but you definately have to listen for yourself.
