I have a crossfire XT212 running off of a Crossfire VR1000D in a ported box, tuned to 34 hz. I was just wondering if I should have put anything in the box. It sounds great, but I'm just wondering if it could sound better. Would some polyfill or acoustic foam behind it be a good idea? Attached is a picture of the layout of the port. Thanks.

If you want you can attatch some fiberglass insulation ( better than polyfill ) to the sides of the enclosure. You dont need it on every surface.

Are you talking about the yellow insulation in house wall? And what surfaces would you put it on?

yes, it helps out the bottom end.

That's awesome. Being that I'm just down the street, I might have to make a stop by. It's there fault for leaving that ugly building torn up for weeks. So just on the left wall and right walls? Not directly behind the sub at all?

Should be good enough.
I dunno if there is any left. They left the back door open when i went to get mine....

Supa, FG isn't actually better than polyfill, as they're used differently.

in a SEALED box, fill helps bottom end, as it makes the box act like it's larger..

in a PORTED box, fill smooths out peaks

i like the peaks, it doesn't sound natural, but when a song hits one of those sweet spots, it makes me smile

Ok....for example fiberglass is probably the best material to use for damping a TL, but polyfill in a small sealed enclosure is what you want for that application.

His enclosure is ported

Yeah then in that case, a good damping material like egg crate or FG would be superior. I was under the impression you were saying overall it's >.

I used 1 sq ft. of 2 inch acoustic foam on the back wall of each of my sub box chambers. I like the way it sounds.
I think it helps with the standing waves in the box.

I also fiberglass resin the insides of all my enclosures to make them as air tight as possible.

While I do have 4 12W6V2's I'm not a bass freak. I like a lot sometimes but most times I keep it pretty even with the rest of the music.

Yes.

A small child would work great.
