Just got a pair of these EMF speakers to try out and i wanted to share a few pics. I have been looking for a good pair of speakers for my test bench and these things seem like they will work great. Just sitting on top of the car hooked up to an amp, they get to moving pretty damn hard too! I bet if i built some small ported boxes for them, they would slap at LEAST as hard as a good 8" Anyhow, here is a few pictures. If i make something for them, i will update this thread.
I believe these are primarily made for motorsports, such as a Polaris RZR like mine. My system is already done though (as you might already know )
Anyhow, i am not to familiar with this brand but they seem pretty well built and sound good so far. They are actually in the DGAF car at the moment.
