Read through the patent earlier today, pretty interesting..
Mainly it's the surround that's patented though, a couple motor tweaks as well to get the maximum excursion out of a square diaphragm or something like that according to the patent //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif.
Now why don't they take that R&D budget they waste on the JackHammer 24 and put it to good use and MAYBE actually make a few subs that'll be worth something.. I mean their 95 series and such are decent, but for the most part MTX is //content.invisioncic.com/y282845/emoticons/nono.gif.eca61d170185779e0921b0faa9704973.gif
