The Dayton doesn't NEED all that power, but why the hell not? It's just offering more performance for your dollar than most other subs in this price range. It may also sound tighter than the SVS because it's sealed, you wouldn't understand if you haven't heard a well made sealed sub. Due to the sub being sealed, it isn't as efficient as a ported sub because you don't hear the sub drivers backwave. It makes up for that loss with all of that power. Just setting the facts straight.
