Dust cover for speaker RCA terminals

[gabrielb]

Dust caps for the amplifier RCA input are a dime a dozen since they all confer to a single size.

This is different with RCA connectors used for the speakers as each AMP and speaker got its own private size.
I saw an interesting solution using an "RCA Protection Cap Plug Short-Circuit Socket" which could fit any connector.

Isn't there a problem with short circuiting the amp/speakers?
Is there a similar solution using a non-conductive material?

Is the dust issue even real or can I safely ignore it?

Keeping equipment clean may improve lifetime because dust inside can affect airflow, but it won't affect the sound.

Yes, you should never short the amplifier's speaker terminals.

BUT the photos you shared are RCA shorting plugs for input. They don't look like they would fit a speaker terminal. Shorting unused analogue input RCA sockets can sometimes reduce noise (design dependent).

RCA sockets are the same size on all components, including amplifier and powered speakers.

Shorting plugs might offer a benefit on unused inputs (although I doubt the will in practice for the overwhelming majority of equipment). Anyone trying these wants to be careful not to accidentally place then out outputs instead of inputs though or you could damage the component they are attached to.

Covering it helps reduce oxidation

A solution, desperately in search of a problem.

Thank you all for the help!
I will try and find a fitting rubber cap for the speaker terminals.
I wonder if I can simply use the fingers of a black latex glove as they stretch enough to cover all terminal types and should not be conductiveץ
It will protect against dust, but nothing else
