Robert, I think this can be done but it is not a matter of a simple driver swap. There is an entirely different crossover to accommodate the filters unique to the diamond tweeter. At the same time you could upgrade to the newer BCC drivers that the last generation of the Contriva Diacera used. You need to speak to Tidal about this directly as they would do the work. I can tell you that as good as the Piano Cera was, the Piano Diacera was much better.
