Default High Efficiency Planar recommendation - an oxymoron?

Back in the mid 1970s, I heard a pair of Bozak Concert Grands at a friend's home (the chief engineer at McIntosh Labs for their first generation SS gear). I never forgot the imaging these refrigerator sized speakers produced nor the transient response and low bass coloration. But nothing is perfect: they totally died at about 8KHz.

Last year, I bought a pair of the B-302A and some extra Bozak woofs and tweets and came up with a novel version by busting out the mid and tweets in their own satellite cabinets saving the original cabinet for the Isobarik woofs.

The system still has that classic Bozak sound but still misses the top two octaves (we won;t talk about the basement - 38Hz is about all I can get).

I like the sound of good planar tweeters, but most have low 1W sensitivities. I want to take out one of the four tweeters and pop in a small super tweeter, passivly crossed before the 8KHz rolloff.

Matching one to the high sensitivitiy of the Bozaks will be a challenge. Any suggestions?
