Don't expect too much from the tweeters.I remember the day in the 50's when my dad came home with a brand new Telefunken Opus 7(with 6 loudspeakers)to replace our old faithful Kungsradio only with AM.
I remember that the sound from the electrostatics wasn't very impressing even when new...on the other hand the normal tweeters were quite good.
A quick calculation on my calculator on the net shows 12,7 kHz as crossover frequency.
