One sure way and I mean
sure way to get mixes to translate is to use a single small mono speaker like this:
http://www.soundonsound.c...s/avantonemixcubes.htm You need to sum left and right of your stereo buss and feed it into this speaker. They make an active version too if you don't want to mess with amps etc..
(Do not use two and put your mix into mono! not the same thing) The idea is you sit directly in front of it quite close and turn it way down. Once you pull a great mix on one of these it will translate to everything else out there, period! I have got a slightly different speaker to this but the principle is the same. I spend hours on the small mono speaker. All you need your main monitors for is checking bass and reverbs mainly.
The small mono speaker shows off what I call the
critical mix and it is very important. And by sitting in front of it at low volume the room acoustics have NO involvement what so ever and as a result will not influence your decisions.
If you are only mixing on bigger or your main speakers you are still shooting in the dark to a certain degree. You will never get it 100% right. The small mono speaker ensures you do, simple as that. People who disagree with this are simply not using a small mono speaker and therefore don't know how good it really is. If they invested in one and used it all the time they would never go back or say anything negative about it because there is nothing negative about it!
