Phil, Try puttin' together a reference CD of Songs you know are mixed well, Such as Dr. Dre and test 'em out on different speakers, really pay attention to the low end, thatz what you want to look for. Some people like to mix on Speakers with enhanced bass frequncies, some don't, it really depends on your preference. I have the Event PS6's, those are quite nice, they have a really good stereo Image. A little too much bass, but i check my mixes on different systems anyway.
