[QUOTE="Spkrman, post: 1061035, member: 548682"] WHY YOU WANT A PORTED BOX: "I don't want it TOO loud" "I'm just for sound quality!"... heard that 1000 times. The truth is that a ported box can be better for both sound quality AND spl. Why not take both? A proper ported box will be considerably more effeciant than a sealed box. A sealed box, for example, will do 135db at full tilt. A ported box with the same woofer and amp may do 140db at full tilt (can be more or less, keeping it even for the sake of argument). That means you have 5db more potential in the ported box. For the sealed box to get to 135db you are pushing it hard, while the ported box will be loud and clean at the same level. Get where I'm going? A ported box gives you HEADROOM! When you need more output, perhaps for a short burst of bass, the ported box is there for you, while the sealed box just distorts. Lets not even mention riding on the highway and trying to overcome road noise! Ported box = less stress on your sub, on your amp, your electrical system, and your wallet! [/QUOTE]
