2006 kicker l7 or the 2002-2005 kicker l7, are the older models built better then the newer ones. I heard from some ppl that they used a diff cone with the 2006 one and isn't as good as the old ones used to be is this true. the new ones are the all black ones and the older ones is the silver and blue faced ones.
Don take my word for this, BUT, i have heard quite a bit about the old squares cones blowing out. So im guessing that the new ones have better cones. Juss google it...
