We are currently using a 4 ways + 2 sub installation in a 20 * 25 m room. I wrote a (very) simple 2-to-4 panning patch to let a stereo image turn following an angle message. Even with a simple algorithm, I get pretty good results, which are OK for our goal (dancer equipped with sensors). Also, I can narrow the stereo field for better tuning of effect with respect to the rotation speed.

nice, what brand of speakers did you choose?

This article gives a good overview of some options:

One thing to think about is that with 8 speakers you can build up a

fair amount of amplification (as opposed to 2 speakers) so you can

take your budget a bit further by getting better quality but smaller

speakers with a subwoofer. Genelec, dynaudio, adam (for cheaper) and

earthworks (for fun) offer some great options along with mackie and

meyer. For that budget I would go with a passive system.

Even better, as the difference between PA and studio monitors is that 

studio monitors have to be more precise (better) in terms of sound and

PA speakers have to be more solid for carrying them arond.

But if you have a fixed installation in a room, the latter doesn't apply...
