actually ask polecat, but the new subs can actually hold alot more power (as long as your conservative and given the proper install/box). plus the look of the cone is different. and the older ones will be cheaper cuz they're harder to find.

pretty sure they changed the coil and the spiders...and the cone obviously
They wouldn't make the new version of the sub inferior to past models //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
