so, crossfire is making these again?.....sweet, i hope i can get some re-cone's......anyways, these are awesome subs....just about the only ones that can compete with l-7's watt for watt. i pushed 2 10's to 146.6 on a single directed 1100d. i haven't metered this one, but it hit's very hard and deep at 500watts. I'd estimate high 130's under 50hz.....
