ADS L710 speaker spring connector repair experts

I have a nice pair of ADS L710's (original owner) that cut out periodically on one speaker. I am pretty sure the +/-spring clips on rear have become loose somehow and need replacement or repair. (If I push on either of them sound returns) There does not seem to be any way to remove the clips from the rear (no screws, etc). I'm guessing you have to remove one of the woofers and get at the clips from the inside of the speaker. Does anyone have experience with this repair and have tips on difficulty? I'm fairly handy but don't want to pull out the woofer without some sense of what I'm getting into. Thanks for any help.

They might if I could figure out how to remove the old ones!

If you look closely at the photo on ebay, it appears that they are secured by a screw...which assuming it is through the speaker wall suggests that you may be able to twist them off (unscrew them).  But there is always the possibility that the screw head on the inside of the cabinet will turn as well which will mean you will have to drop the woofer to get to the screw head.

Yes, early versions were as you describe and then they produced a few more "sealed backplate" versions with screw posts and then with the posts and a single fuse holder.

Afterwards they were accessible from the back of the speaker.

You will have to remove the woofer to see what's going on and if the crossover is in the way.
