yeah... mean i used to have kicker cvr 12" in a prefab and thought it was loud, then i got this and built a box the right way, got my amp all hooked up everything the right way, threw some deadener in there, made sure evertyhnig was wired correctly and had enough power...lemme tell u it really does wang in my...ears
EDIT: and also, dont just take my word, or anyone's word for that matter, period....go on google and read some reviews on the woofers you are looking at, and look at benchmarks etc.
