oh wait a minute your building your own enclosure? NICE, like pro mentioned, the only time you use polyfill is when you have a tight spot and the required air space is not enough for the speaker to work properly. So in those situations you use polyfill since it slows down the back wave allowing the sub to perform as if it was in an larger enclosure.
The only thing about ported, you want to get the right port and all since your gonna ''tune'' the box to a specific frequency. You do gain about 3db in spl, but with certain types of music it can sound kinda boomy and slopy. Slot venting allows a slightly ''wider'' range of freq's. The down size is that this is slightly more difficult to built esp is you never built an enclosure. Also I sure you did already, but make sure the sub can perform in a ported enclosure. When I measured the back section behind the seats, I figured about 1.5 good cubic air space for a box. So if your sub requires more air space, then you would use polyfill depending on how much more space you need.
