Okay, I've had a raging hard-on, ever since someone posted about having a pair of these the other day. 2400 watts into a 21" driver, lawdy-mercy don't you know this dude would pound hard! Finally got around to doing a bit of research about power draw. Ouch, 12.5 amps draw? I realize you could do 80% of most weddings with one of these but, if I'm reading correctly, you'd have to pull a separate circuit to power the one sub. Yea, I know, "real tools, real tools".
