I have a room that is 24x14x8. I hope to soon set up a home theater system in that room. My other speakers will be Klispch RF-3's, RC-3, and RS-3's. I am looking at either a SVS 16-46 CS+ or a CS Ultra. Will this be enough sub for the room Im putting it in? Also is there a significant difference between the CS+ and Ultra subs?
