Used to be a guy back in the day that had a Chevy Blazer with a bunch of Crossfire subs and Earthquake amps. Shit was loud as fu ck, in my opinion. Sounded good doing it also. He used to come to all the local shows, idk the numbers he put up though. Overall I think Crossfire has quality products
Crossfire is getting to be top notch.. Their new woofer looks promising.. I'd either take that one or the SMD woofer but this Crossfire has more options.
A local shop here sells them BMF's and the setups I've heard with them were pretty loud
i used to have a crossfire bmf 15 inch sub. boy do i miss that thing. i gave it to my friend when i got 2 type r's. I fed that thing 600 watts in a ported box and it hit as hard as my type r's did.
I had a single 15" BMF XT2 (old style) on a saz1500... shit was loud as fvck in 4.5cf tuned to 33hz. coils got hot as hell though, ended up causing thermal damage. sounded good for daily, and could still take a lot of power for burps
edit::::
here are some pics of the one i had, was a beast
in one of my temporary boxes ive had to use a couple times
My 2 10 inch Crossfire BMF's with the same power eat the Kicker CVX's for breakfast. lunch and dinner. They get much lower in bass. Very underrated sub.
