Triton seven is very new. I have not even heard them yet (missed RMAF this year). It would be a sweet shootout I think. A lot would depend on the cabinet build on the N3. as they are DIY, so naturally they are all of different build quality. I suppose most of Danny's kits go out with good caps in the tweeter circut. Not sure about the Triton at $1400., they are most likely use import budget priced poly caps.
I imagine the Triton 7 might have a bit more over all low bass due to the alignment. Not sure about speed and control down there with those passive radiators though.
