If you aren't planning (or don't have the processing) to go active I would suggest bridging that 350.4 to 2channels and just find a decent set of comps that sound to your liking.

Infinity's are a great bang for the buck comp set. Depends on if you like their sound though. Not that they're bad sounding in any way but I don't know your tastes so.....
