I've been planning on a single Diamond D912 for my sub stage, but lately I've been looking into the IDMAX 12 and am very intrigued. Which one of these subs would be the best for daily and also possible novice SQ competition? (the kicker CVX is also an option). I'm not really looking for other random sugguestions, unless you have one thats in the same price range that really beats the others. Let's hear what you guys think
