I had to give up my treated room for a terrible sounding one. I'm not sold on room correction software so instead of going down that path, I chose a brand I trusted and got a set of speakers so small, they wouldn't interact much with the poor room acoustics. The drawback is that they don't deliver much bass, but for that I have two sets of capable headphones.
I got the stands for the 8010s also, so I have them at ear height, which makes a big difference. Between these little speakers and my headphones, I'm getting consistently better mixes than I did in my treated room and Dynaudio BM5 MkIIIs (that's not to say that those speakers don't deliver, because they're really good also). Part of that is due to experience, but these Genelecs are incredibly clean, clear and analytical and I trust them for everything from the low mids and up.
When it's time to move to a new, more permanent mixing space and upgrade the monitors I will probably go Genelec again, and use the 8010s as a pair of nice hi-fi, bookshelf speakers :)
