My tactic is a dedicated room with a shut door. I ended up conditioning them to never enter that room (different color carpet). So in case I do leave the open, they usually stay out.
And they know I mean business too. I lost several cone surrounds and an entire subwoofer but trying the "leave the grills off" tactic. I even caught one of them "trying to mark his territory" on my left speaker. I got both of them "fixed" and de-clawed the next day. Pretty much from that day forward those cats *knew* who was in charge. And they've been angels ever since. ;-)
In the cats' I scrubbed the speaker down and moved the system over to my brother's place. Then I eventually said up said dedicated listening room. No problems anymore...
