The one I had wasn't ported, but it sounded pretty good. I have a regular cab though so a lot of subs will sound good in there unless they just really suck. I'm going to try out a ported box on my next set up I go with to see if there is a huge difference or not. You could probably save a lot by just building your own.

I know its a little late on the post, but how did that pro box sound. I was thinkin bout getting the ported one. But if its not stupid loud ill save the money and build my own.
