Can I use a prefab ported box and use poly fill to tune it?

you should Not even need to use polyfill in a normal vented box anyway actually.

you shouldn't need to but it will make it sound better

In a ported enclosure, keeping port length and area the same, less airspace will raise your tuning frequency.

im asking why would he want to raise the tuning, not asking why does it raise it.

I don't think he wants to raise tuning, it's going by that the polyfill does displace air, which in turn can raise tuning, I assume this is NOT his goal, but a byproduct.

I coated the inside of my car with polyfill when it was in my ported box //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Definately need a screen over the port. I don't think you can staple/glue every bit down, you're bound to have some blow out if you use it.
