Crossover Capacitor In Parallel with Woofer


I successfully recapped my Altec Lansing Bolero 890C speakers and they sound amazing.  This has helped me understand how crossovers work but there is a section in it that is still strange to me.  It looks like there is a 6uf cap and a 5 ohm resistor in parallel with the woofer.  Is this making it a 2nd order (12db) crossover point?  Can anyone explain exactly how that cap is working on the low end or is it just effecting the slope of the the frequencies being crossed over? Thank you in advance.

It is certainly doing impedance correction,  but 6 mfd sounds very low.  Years ago,  I rebuilt a pair of these and ran actual curves... I'm sorry, I just don't remember, but It seems to me that it was more like 20 to 40 mfd to correct the impedance bump in these. 5 ohm does sound right on the resister.
