LoL um that stroker wasnt in the optimul enclosure there specs say optimul is ported if it was the 12" It should of been in a 2.5 cubed box ported to 28 hz for optimul performance that box was small, but it did look like the 1.1 sealed they recommend for a sealed box lol even at 2000 rms in a 2.5 cubed sealed box with hella clipping my 15 lasted almost 20 minutes and it only fried one coil.. plus the video doesnt say what size the box is, it doesnt even show them hooked up to the crown amps.. i dont know i was happy with my stroker and im even happeir with my stroker pro,,, anyways those orion subs do look nice just a little skeptical on the tests thats all..
