Damn I can't find any kind of reviews on these. All the sellers' sites don't seem to0 legit either. I'm in a dilemma between either this shallow 15" or a pioneer premier 12"...both are 400 rms, but I think I'd trust pioneer more than earthquake sounds. But a 15" would be sick haha I'm just scared to get a crappy sub for a lot more money than the pioneer.
