** If the large value electro is wired in parallel with the woofer, it does little harm. Non linear distortion products do not transfer to the mid or treble drivers. FYI:
My last project involved completely stripping and re-engineering an old pai r of AR2Axs - the cabs were in good nick and cost me $100.
I fitted Peerless, 10 inch woofers ( 830668 ) with a 12dB/oct filters that used non-polar electros and a 2mH air inductor.
The mids were 4inch Peerless ( PL11MH09-08 ) with 12dB/oct filters at 450 H z and 3kHz, using only 250VAC rated film caps and air inductors. I installe d a thick walled, cardboard tube from back to front to give this driver its own, 2 litre enclosure - stuffed with absorbent wadding.
The tweeters were 4ohm PAE 1 inch soft domes ( PAE 25TG18) with an 18dB/oct filter using 250AV caps and air inductor.
I spent considerable time doing tests with an AKG CK2 condenser mic using 1 /3oct pink noise and 4 cycle tone bursts.
There are a couple of 5 watt WW resistors involved, no variable attenuators and the final touch was to install Speakon connectors.
On good programme, they leave any AR I have listened to for dead.
Just a basic, but relevant point - Dynaco cabinets of that vintage are not sealed.
And, yes, when speakers rely on mechanical vs. soldered connections, they b ecome weak points. AR (et.al.) pots. Dynaco rotary switches. Internal banan a connections (yes, they exist). And more.
As a hobbyist with a 40+ year immersion in the hobby, and in a region where all sorts of things are thick on the ground and having lived within 100 mi les of a dozen major audio manufacturers, I have seen *lots* of strange stu ff. Most recently (May 12th), a Dynaco ST70 and a pair of MkIIIs marked by, and from a Hammond organ. Go figure.

Crimps are very good when done correctly. I think what the OP is referring to is speakers connected with things like the push on connectors and phono plugs. Not realaly a good hard mashed together type of connector,but one that slides off and on.
