Right now I have a sealed enclosure for my Eclipse 8122 that has a sloped back so it snugs up to the back seat. I would like to try building a ported enclosure to see if I can get a little more out of the sub, however I would like to once again slope the back so that it fits against the rear seat. Can this be done with typical slot ports or will I have to go with round ports? Any links to pictures or designs of such enclosures would be greatly appreciated.
