Rock-ola 418S optional speaker box 39400-A capacitor replace

[marcometal]

Hello,the capacitors in this speaker box ( only tweeters) have a value of 2mF on the schematic but no indication of the voltage.Dimensions:4.5cm on diameter:2cm,any indication has been lost in time.
I measure 9mF and low ESR and i want to replace them.Could somebody give me information about a replacement,non polar,voltage rating ,manuf.etc.
Thanks in advance
