Ported all the way. Put the port facing away from the front seats you will not hear it breath. My ported box sounds cleaner and smoother than any sealed box I have had.

 

If you had an L7 in a sealed box and it didn't sound good, then you didn't do it right.

 

Your 100% right they are designed for ported boxes

 

Negative ghostrider. They were designed for sealed inclosures.

 

I bought an L7 from a shop with the sub already mounted in a ported box. The box was designed by Kicker to get the most sound out of the L7. With the amp I have on it, it makes bass somewhere between ridiculous and absurd. It actually hurts to turn it up. I would go with a ported if you have the room.

 

I Had Two Db Drive Ten Inch Subs In A Ported Box. But I Switched To Sealled I Personally Perfer Sealled Over Ported.

 

I have two 12 inch L5 subs in separate sealed boxes with a jbl 1200 watt amp driving them. It hurts to sit in the truck at full volume.

 

Well, this thread is kinda old but I would put up another vote for a ported enclosure. It would have to be about 25% bigger than a sealed enclosure to get the full advantage of having it but would be worth it IMO.

 

Ported is louder, sealed is cleaner!

 

he ended up going with a ported enclosure. his **** hits hard as hell with 1 twelve. he needs to dynomat his cab though
