I'm just learning that people actually put two subs together! I see what you are saying. With that logic, I think I'd rather get the EX now, and another this spring or summer when they go on sale again. If it weren't Xmas time, I'd get two EX's or Hsu's right now. From what I've learned, the EX or Hsu will get much lower frequencies and I'll hear better base at mid level volumes (regular tv watching)? Two EX's would be better than two RW-12D. The Klipsch goes down to 25Hz while the EX can hit 16Hz, in optimal settings. I might have something wrong here vocabulary wise, I just started this process two days ago. I appreciate the help though!
