Great driver
I modified the enclosures in the door of my Lexus to match the specs of this driver. Volume was perfect I just needed to enlarge the port.

I ran these for a summer off a jl 600/4 and a pioneer 99rs. They handled a ton of abuse but the one in the passenger side door finally gave in. I’m purchasing another pair and I’ll be slightly nicer to these.

The mid bass was surprising and it was really nice in a 2 way configuration- effortlessly matching the morel 1” tweeters it was paired with.
