[QUOTE="audioholic, post: 7340701, member: 549629"] 1) Yep. I believe I already mentioned in this thread that the 12-spoke frame will not allow 40mm of excursion, its max being in the mid 30's. The 4-spoke ("Venezuelan") frame was slightly less than that, but basically the same, iirc. 2) Yep. I also already mentioned that the guy claiming his HCCA moves as much as his friends' XXX is comparing apples to oranges. Ive seen xmax referred to in terms of BL loss (70%), distortion thresholds (THD levels), and the most simplistic overhang measurement. He used none of these to compare the drivers, so his conclusions on xmax comparisons is fatally flawed. 3) Seems like you are just repeating the same things Ive said already. lol [IMG]//content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif[/IMG] True, the SSX motor cannot support anywhere near the claimed xmax figured stated in this thread.
