There is no such thing as a full range stand mount loudspeaker. They all need subwoofers for the best performance and our cat is scared to death of them.
Don't sell your Golden Ears. You can train the cats to stay away from them. You place these mats in front of the speakers. Every time they try to walk up to the speaker they get a small dose of static electricity. It will not harm a kitten at all, it is just strong enough to be unpleasant. After a little while they won't even think of heading in that direction. I have Sound Labs speakers, ceiling to floor grill cloth and our cat could care less. We took the mats away a long time ago.
