If I understand what you are asking correctly, then yes, it is sometimes referred to an iso loaded enclosure. Just be sure to then wire the drivers out of phase as to essentially use the enclosure as a closed system to transfer each driver's displacement. Or you could have one sealed inside the enclosure behind the other driver, and wire in phase. Check out the12volt.com's page on enclosures there bud.
Sorry. I'd reply much more but hey, it's party time as it is getting colder out now and downtown is booming right now w00t. And I might have pre-gamed quite a bit. Lol giggity.
