Does anybody have any feedback on the older silver L5 vs. the new black 2008 model....Pros? Cons? Need input asap as I'm purchasing it in a couple days...thanks in advance

Also, I had a ported enclosure on my JL w7 13.5 but it was too crazy and am downgrading. Is ported or sealed the way to go with the 12"......looking for good sound quality while still hitting hard enough to sound good from the outside. Thanks again.
