An autotransformer was what I suggested! Active is in as much as I suggested a separate power amp of just a few Watts to drive it. This allows the super tweeter level to be set with the vol control on the separate amp and isolates the main amp from any undue load from the tweeter/autotransformer combination which may spoil the top end at audio frequencies coming from the main speakers. As we're talking 20KHz plus here a small ferrite transformer should do the trick.
