I've got an old school Orion setup in mine - HCCA 6-1/2" Separates in the front and 2 XTR Pro subs in the back. I personally have always loved the sound of the classic Orion amps and drivers. Stay away from the new stuff though - they suck. You can still buy a lot of brand new Orion equipment off eBay, and IMO they sound better than just about anything else out there.
