I'm just curious if the .6 cu. ft air space is the gross space or what... your space should be after subwoofer displacement... the Infinity sub is quite a bit bigger than the solobaric so you have to figure for lost enclosure air space... no doubt that putting a 12" in there in place of a 10" will increase your output but by how much is big question. What kind of bass are you looking for anyway? You should get a pretty decent output with snappy, tight bass but wouldn't expect a lot of deep, boomy bass... but who knows, maybe thats what your lookin for.
