[sundownz]

what size sealed box would be good for this sub?

0.25-0.3 cubes.

I'd imagine one could do some pretty nasty things with these in shallow applications like behind the seats of a truck or underneath, etc.

so how would these do in like a rear deck? I may just wait and get 2 of these and sell my dd1008. or give it to you for comparison testing in return for one lol

The suspension is not incredibly stiff so mechanical handling will be down IB but they should sound fine. Had some folks use the E8 v.1 IB and love them.

Measured D4 specs. I manipulated the winding width a little so the D4 actually ended up with slightly higher motor force than the D2 -- good stuff
