They've got a 4500W & 6500W RMS 12". The 4500W has 50mm x-max it says. Has anybody ever used these at RMS? 14-16 sqin per cube? Are these TC sounds subs? 89db 1w on the 12". Looks like two BTL's in one.

They're mostly sold in Europe so I doubt very many people (if anyone) will have experience with them here.

There's nothing too exceptional about them so the cost of bringing them over usually outweighs any advantages they have over something for sale in North America

Must be asking because he's got a deal on them (or at least interested) ...

I don't know of them either, start Googling and searching the forums, especially international one's.

50mm (1.9 inches) or more of xmax isn't hard to find.
I have to say it's heat dissipation rating is pretty high though, I wouldn't think it would be possible to run that much power daily on those things.

I doubt TC makes them.

I'm aiming for two 12" foreward fire in my trunk, 6x15 slot port, 1" mdf & spacing. RE's box calculator (2.5 @ 33 each) says the back wall will be 18-23" from the back of the sub. How far should it be for sufficient dampening? The trunk face is exactly 17x37. I don't want more than 2 or 3 batteries, it's too much weight. What can I power with 1 batt under the hood and two in the trunk? Would I power the components and deck with the one under the hood, and the other two batts only on the subs? Those GZA's look insane, 9kw on 2 12's would shake some stuff. Would you say 1 batt per 3000W? I could get away with 3 batt's.
