There are no "best supertweeters to add to pair of horn speakers" BUT there may be supertweets compatible with your particular spkrs.
Can you specify SENSITIVITY, FR figures and horn type used, for yr spkrs?
Most importantly, what is it that makes you feel extra tweets are necessary -- i.e. what are you trying to improve?
Cheers
