I draw this xo circuit from a 15 yr-old Vocopro Karaoke speaker. There are no markings on the inductor or the mylar caps.
I don't understand why the 8 Ohm tweeters are connected in series. Should I replace them with 2 4-Ohm tweeters.
And what is the purpose of the resistors & mylar caps in series?
I'm replacing the 4.7uF cap and re-wiring it with 14 gauge stranded copper. Thanks in advance.

Perhaps it is to modify the directivity by asking the outer tweeters only to produce lower frequencies. It's difficult to be sure without knowing the physical configuration.
FWIW, I found that C1 & C2 are varistor, not caps. They are there to protect the drivers, in case they're overdriven, which would never happen in my case.
