Yup, when I saw the graphs for it a long while back, I thought it might be a great fit...I don't think the DI would be as smooth with the Bliesma or Peerless, but it might be acceptable. That DA32 is a serious tweeter for the money.
I should receive my SB radiators in a week or two at which point I can get this project buttoned-up & start with the tuning!
(I just discovered the Directiva project a few days ago. It changed my mind to try the passive radiator vs. the ridiculously long ported configuration I was shooting for.)
I might try this out w/ the new balanced miniDSP Flex + my NC252 Buckeye amp.
