So, what's the general opinion on the best sealed enclosure size for a 15" D2? Seems like a lot of people prefer 2.4cf? Also, is that before or after sub displacement, and what is the displacement of a 15" D2?

Also, does polyfill do anything besides making the sub think the enclosure is larger? If that's all it does, why not just build the enclosure larger in the first place?

Basically all this is the long way of asking, how big should my enclosure be??? Thanks~

I think the displacement of it is .3 cuft. I have a 2.0 cuft sealed after displacement. It does just fine. That is what it says on the website. I still need to add polyfill. I have meant to do that for a while.

The minimum recommended enclosure size is 2.0 cubic feet. We would like to see them in bigger boxes though. 2.4'ish would be great with light polyfil stuffing.

Would that be before or after sub displacement?

looks like I need to build a bigger box. damn. oh well. if it will be better for the sub then I will do it.

would I see/hear a difference with a 2.4 cuft box??? or is it just better for the driver.

Better efficiency, a little bit more low end...should be fine...see how it does...you can always adjust box size using a couple 2x4's, or polyfill to increase things...
