Right on! To put the good fix in, just get rid of the connectors and solder the wires direct to the board? And I would definitely recommend changing out that electrolytic cap for a good polyester or polypropylene type. Good luck!

thanks.  all connectors on the board itself are soldered - the connectors are only to attach to the speakers (I might keep those for ease of attachment/removal of the drivers).  They did actually use several polypropylene caps on the original build, but have that one electrolytic you see, and two electrolytics on the midrange bandpass.  Not sure why they would have used electrolytics when polypro were available?  I am not a EE - so I do not know enough to know if there was a solid reason (other than cost...)

For sure the cost. The electro would be less than half the price of any non-polarised cap the same value and voltage. When you have to make 10000 pairs that sh1t adds up.
There's a theory that if you connect a 1.5v battery across the electrolytic to maintain a polarising voltage, it sounds better. JBL do it in some of their expensive domestic models! Adding the battery holder is still probably cheaper than using the non-polar cap...
