cats and speakers - looking for clues

For me with Sonus Faber's having two large quality cat scratchers in the room has luckily kept the current Maine Coon interested enough to leave the speakers alone.  We also trim her nails and hang together listening to music. She likes acoustic Jazz and chamber music, but not the blues or rock. 

The first Maine Coon almost lived outside full time and couldn't care less about my speakers. Whether or not your equipment will be safe depends on the cat and whether it has its own space and stuff to interact with that it likes better than your speakers, chairs and couch.

Cats hate citrus and mint, so try spraying some citrus or peppermint spray around your equipment/cables and they’ll likely get the idea quickly.  Might need to re-spray a few times a week for the first few weeks, but cats are smart and creatures of habit so once they learn they’ll likely stay away.  Hope this helps, and best of luck.

They make quality custom covers, easy to place and remove. 

The situation depends on the actual speaker and cat. My wife foster cats; none of them bothered my TADs ME1s. Some liked to lay on my JBL 4367s, but I had the covers for that. No problems. 

I have both floor standing speakers with grills and cats. My cats do not scratch any furniture. That is essential. This has to be trained as kittens. If adult cats are scratching what every they like you are left with 1 choice, scat mats. https://www.amazon.com/Petfolio-Pack-Scat-Mat-Cats/dp/B0CD. Not a good looking choice, but cats will not walk over these. Yes, lemon or other citrus scents can help, but you need to own frequent spraying and disciplining. That is too hard for me. 

I am not at all concerned about your speakers...........it is you that concern me,.....listenig to music and having a cat on your lap......could be a problem,....perhaps other listeners might reflect...
