After playing with Dirac I wonder what effect does replacing speakers have when using room correction. If we anyway match speaker+room response to target curve, what kind of difference one can expect by replacing speakers if current ones are of more-or-less reasonable quality? At least when I was buying my speakers (10+ years ago) I remember hearing different "signatures", they just sounded quite differently to me.

Interesting... This is very similar to what I ended up with. Do you listen on lower volumes typically?

Yes, I'm doing exactly this. I've just seen target curve guidelines for other software, maybe it was Acourate where the suggestion was to not deviate a lot from the shape of speakers curve, especially not trying to improve dips in frequency response curve.

I have full range speakers, but I'm using also sub (crossovered in receiver). I've got slightly better results with this setup. I'm planning to take day off next week and try different approaches in setting up Dirac and speakers from scratch. The default curve sounds very much similar to "Music" Audyssey curve in my receiver which I don't like because it's too thin-sounding, however their "Movie" curve has some other problems like non-formed bass.

I'm evaluating Dirac right now and I wonder if there are good guidelines on target curve design. The default suggested curve did sounded better, but it was still lacking on low-end so I ended up raising low frequencies slightly. But I'm curious if it should really be just downward-sloping and not somehow follow general shape of original speakers?
