This is my first post here after about a couple of weeks of lurking the boards. I have learned a wealth of information from all you guys/girls so thanks a lot.

Anyways, I've started making an ported enclosure for 2 JL 12W0's and I am wondering what I should use to make the actual ports themselves. JL's recommended measurements call for one 4" diameter x 12" length cylinder for each sub. I was considering PVC piping that they sell at home depot in about 10-foot lengths that I can cut down to spec. I'm thinking this is the wrong way to go for some reason.

So how would I go about porting the enclosure? And what method would I use to suspend the cylinder. Thanks in advance- your guys help is much appreciated.

I prefer square (slot) vents. They're easier to manage (you can adjust the port area as needed) and they're not that difficult to make.

 
does sound differ from different port types? tubular like pvc or slotted?
Not until you start getting into large drivers that move a large amount of air. In that case i would go with a slot or square port. For something on the smaller side round ports work fine.

I have use PVC before and it works. All I did was glue and tube in place in the hole and added a few small, flat head screws in the inside of the port and screwed it into the MDF.

The black rca out is your mono sub output. That is the one you would use for signal to your sub amp.
