anyone have any experience with these drivers? I just got the new total car audio mag and almost all of the cars in the "prestigious event" were running these subs. Here is a link of that line of product http://www.cbrstereo.com/index.asp?PageAction=VIEWPROD&ProdID=897
Why do they even bother with specs if they are not going to list the Xmax, it's kind like listing a motor's bore instead of the displacment. Maybe they were key sponsors and gave them to everybody entered.
