well.... in the first place, the size of the room doesn't really matter, a good room is a good room, if you have large monitors you can use them, if you have nearfields you can use those, doesn't matter.
NS10's have produced more hit mixes than most likely all other monitors combined so no matter how much you guys slate them, you're swimming against the tide, it doesn't stick.
Cyan's "put tissue on the tweeters" invoked some funny responses, but is actually a very common trick, lots of people put tissue or cotton wool over them.
With due respect to Aniram - it sounds a bit like a version of a volkswagen advert "drivers required" - in this case - have gear - experience required.
Aniram - which questeds are you talking about? are you thinking soffit mounted? free standing? etc. let me know and I could give you some advise, but don't blaim monitors for things not sounding right.
Using subs if you are not a very experienced engineer is one guarantee to completely fuck you up. Leave those things for surround stuff, they would only confuse you.
Listen, practise, mix 20 hours a day 7 days a week, listen again, learn to use your ears, it all takes time.
If you are not happy with your mixes, work on them, until you are happy with them. I reality, thats all it takes, work, work, work, listen, listen and more work.
As a little note of consolance - I just heard a grammy winning CD - it was the most godawful fuckedup sounding piece of total shit I've heard in a long time, still a lot better than FT ever managed, but still bad enough to shoot the engineer or even send him to Full Sail - even there he'd learn more :>)
