First of all, the W7 isn't going to remotely fit in there. The magnet won't even have clearance I don't think. Secondly, it would blow that enclosure to bits. . If you are going to run a sub that serious, you need to get a serious enclosure. Honestly, the W7 is pretty picky about Clearence and its got a displacement of 0.09 cu. ft and a mounting depth of 8"!!! Find an enclosure built for the W7 or have one made.
23mm EXCURSION too. Just to give you an idea, infinity 10" subs are typically like 12mm.
