Terminals spade type loosening the binding posts

I'd like very much your suggestion.
The use of spring washer can be probably a very nice solution.

Thanks a lot

brf:"Try a touch of thread locker (Loctite Blue) on the binding post threads."
I think that is obviously a terrible suggestion that is offered here you do not want to use automotive repair materials on your Music Reproduction System materials such as Loctite cannot possibly be good for your sensitive electrical connections if you're terminals are working themselves loose I would humbly suggest they be replaced with high quality audiophile grade connectors that will not be regularly subject to such outright failure mode.

Loctite is not an automobile repair material, but a threaded lock sealer. Loctite is designed for threaded fasteners that are subject to backing out due to vibration.  In addition, Loctite "Blue" is designed to have its seal/lock easily broken for disassembly i.e. not permanent and reversible.  The Loctite is applied sparingly on the binding post thread, and will be not in contact with the spade/binding post interface. 

Loctite red is the type that is hard to break loose. The washers should work as suggested above.

I know this problem.

The issue is actually that the nuts on the speaker AND/or the spades are too hard. If they were soft, they would deform just a touch and grip.

What you want to use are spring-loaded WBT terminals like these:

It is hard to tell, but there’s a spring molded onto the spade itself.

I would never put any kind of Loctite on binding posts. Even though the blue is considered removable, it requires a significant amount of force more than normal to break it loose. Too much risk of damaging the speakers. Plus it is going between conducting surfaces on the binding posts. The red Loctite has to be heated to remove a nut from a stud or bolt. Don't do it.
