Shoot me some links of all 6.5 2 ohm. I took a look and your either out of stock or can't find em.You should be browsing the CDT web store or my store linked in my signature so you can see the current models.
I'm not sure how you got that URL as there shouldn't be an l on the end, but I can get that in a 2 ohm version. It can also be made into a coaxial with a separate crossover.
