The cone has to come off, IIRC. They are usually glued onto the spider and the surround is glued to the frame. They you can access the voice coil and the top of the magnet assy with the cone off...

I ran my 12" l7 subs in .5 cu/f boxes. They were the same size as the flange of the sub and about 10" deep. I angled the front of the box to cut down on standing waves. Very punchy that way, I listen to metal, rock, and tekno, so the subs have to be fast. The tube-like box worked very well, I actually blew the back of the proto-type out when breaking in the subs. Ran them at 3/4 volume for 4hrs straight during a mardi gras parade. Amp never even got warm.

I have a memhis 500d and a 200ab 4 channel to go in my truck. Bought a thunderform box and it came with 2 mtx 4500 10" subs. I will give them a try, the box was 300 bucks with the subs, or 299 without them... Not much room in a lightning, so I am not expecting the world.
