I got my Blacksmith today (Donovan really is the best place to go for TC stuff in the US). I haven't really had much chance to play with it yet; I've mostly just gotten it hooked up and done basic testing to insure nothing on it is DOA.
(Please excuse the crappy cameraphone pics -- it was the quickest way to get a couple shots of the new amp up.)
One thing I am wondering with the Blacksmith: it has a switch for 2ohm or 4+ohm. Running three RS212s should technically fall in the 2ohm range, but TC always said this was fine with the RH450 (which only supports 4ohm) because they "know the exact characteristics of their cabinets)". So I'm wondering if I should leave it on 4ohm when using the three RS212s, or if I should switch it to 2ohm mode for optimal performance.
And not that I'd ever need it, but if 3xRS212 is still 4ohm "safe" then could you run two stacks of 3xRS212 off this thing at the 2ohm setting? That would be.... impressive. Overkill 9000, yes. But impressive, none-the-less. Or does it cap out at 4xRS212? I'm going to assume 4xRS212 since the manual shows 4xRS410s as an example of 2ohm configuration. Even still, 4xRS212 is a lot of air getting pushed...
(And to make things clear, I don't need the 1600W of power the Blacksmith delivers. I got the Blacksmith because it's a proper rack-mount form factor. I have the rack kit for the RH450, but it just looks terrible in a rack. So now I'll rack the Blacksmith in with my other gear [once the new, larger flight case arrives] and keep the RH450 for use as my practice amp in combination with my RS112.)
