just wanted to share my fix for making my speakers cat and grand kid proof!

Chicken wire won’t stop a finger poking 3 year old. Use Hardware Cloth instead.

Exactly, not even 1 year old like my son done on my ML twenty-five years ago.

My friend did this with his old ESS Heil Air Motion Transformer AMT-1A speakers in the late 1970s (which we thought were "high end"). He made some nice wooden frames to hold the chicken wire and back in those days he had to spray paint it black. He stained the frames the same as the speakers. Looked nice and didn't seem to affect the sound at all. He had two kittens and had never had cats before so it was all a learning experience. Worked fine. Grilles were never scratched.

Remember Grandma’s clear plastic couch cover? In the late 60s we had a cat. I bought a pair JBL Dorian S12s. The cat liked the grill. So I took measurements and went to a couch cover maker. Had him make 2 clear plastic covers. Basically like a flat bottom lunch bag. Put the bags over the speakers when not in use. Being clear I could still see the speakers.

 I raised 2 kids and they never went near my speakers. Now I have 3 grandkids that so far haven’t touched them nor shown interest in them. I told them to stay away, and they abided.

they work fine for  preventing grandkids' fingers they are a big enough diameter and round so pretty stiff  the fingers cannot reach the speakers ! and cats reaching thru can't get close enough either 
always someone critical that does not think it through !

Secure the frames across the top of speakers w/ some velcro pads ? 
I had to safety wire my speakers to wall W/ an anchors  the way you do w. shelves and dressers & TV's now  as one kid grabbed it tipped it over ! and it almost fell over on him! - Big tall tower speakers! could have crushed the little guy ! OUCH could have been a tragedy ! 
thx all
