I'd like to see some real TS numbers on the subs and full specs on the amps with testing (along with methodology for both) to back them up. And I'm not saying there aren't any, just saying that I've not seen them.
I've modeled one of your subs for someone on another forum and I've looked at the published specs for the amps she was using but to be honest, they seemed dubious. Of course, I realize that that could have been something lost in translation and that's the reason for this post.
In short, if you're moving to Rome, speak fluent Roman.
