What kind of enclosure is it called when the basket and magnet of the woofer is exposed and firing into the enclosure? can anyone tell me the formula for figuring out volume in this type of enclosure?
No "name" that I'm aware of. If it would be a sealed enclosure with the sub mounted normally, it would still be a sealed enclosure with the sub mounted reversed. You should figure volume just like you would for a normal enclosure, an since most of the sub is now outside the box and the cone is extending outwards, I would guess the speaker volume inside the box would be negligible.

are there more disadvantages to doing it this way as opposed to mounting the sub normally in a sealed enclosure? I've always been a firm believer in a nice normal sealed enclosure, but i have a customer who has a set of audiobahn subs and he wants them mounted with the baskets exposed and firing into the enclosure to he can see his shiny baskets and magnets. I've personally never done it this way, so im not sure how its going to sound.

I asked this same thing just a few days ago, and did some research. I couldn't find any real information on pros or cons, but people that responded said it was fine. I just made an enclosure to ount two JL10's this way. I did it for space considerations though, and to hide as much of teh drivers as possible. I'br only listened to the box for 15-20 mins, and not cranked it up really high yet. Sounds just fine from what I've heard. I never had both 10's together in sealed enclosures before, so I can't comment on how the sound compares directly.
It seems like you have less surface area to radiate sound energy from, what with the dust cover on the inside and all. But your coils should stay nice and cool since they are out in the open...
Sorry I couldn't give you more definitive information.

you said you did it for space considerations, but didnt you first say that you use the same volume for mounting a driver this way? so im confused why you say you did it for space considerations if the enclosure is the same volume?

I decided to go "stealth" and wanted my enclosure as invisible as possible. I ended up making a flat box that covered all of the available floorspace. The box was so thin that a lot of the sub would have to be exposed still. I figured if I flipped the sub over, the "largest" part of the sub would be hidden, so now I just have to disguise about 4" of motor/frame that are sticking out of the box.
