RE: Actively Triamping Magnepan ribbons..do you protect them or not ?

I agree. A series capacitor is not preferable and the best safety device for direct connection to a true-ribbon is the amplifier itself. It needs to be well-behaved at turn on/off and exhibit no DC offset. A series capacitor could still allow significant thumps (the larger capacitor the worse the thumps) to the tweeter on amplifier turn on/off. The only thing it will accomplish is to block steady-state DC.

A shunted inductor will not accomplish the protection goal either. A thumping amplifier (that's a good voltage-source) will still happily deflect the tweeter even though the impedance of the inductor is much lower than the tweeter at low frequencies and DC.
Also, some amplifiers may not like the short circuit at low frequencies.

Cheers,

Dave.
