Since this is an install system and doesn't need to be portable, I'd recommend something like:
2x JTR Captivator 218PRO subs (active)
2x Yamaha DZR12 speakers (active)
1x Behringer X32 Rack mixer and use iPod control
If you call and talk to Jeff, you'll likely get a little bit of a deal on the JTR subs... and if you have any type of relationship with Sweetwater (just call and get a rep, then ask if they have any wiggle room on pricing or educational pricing deals), you'll be under your $12K limit. This system will rock your socks off and will be *extremely* easy to set-up and maintain. Be smart with the gain settings on the speakers and these should last for quite a long time without any problems.
That's my $0.02.
