Child-Proof Speakers

I have a six-month-old now and in the process of trying to child-proof the house. I'd like to keep the sound system in the living room, where the whole family can enjoy it, but concerned about the little one knocking something over, getting hurt in the process and/or breaking a valuable piece of equipment. I recently got a cover for my Rogue Audio Cronus Magnum (so she doesn't get burned on hot output tubes) and bought an equipment rack with closable doors. The next step is potentially replacing my stand-mounted speakers (Sonics Anima) with less tip-able floor-standing ones with more robust drivers (less vulnerable to being prodded by child fingers). Any recommendations on speakers in the <$3000 range? I listen to mainly rock, reggae, world and jazz, and usually on vinyl. I really like the Sonics and Audio Physic sound as well but looking for other options too.
Shumazing, being a young father a while ago with crawling peanuts, my response is that your question is an oxymoron -- there ain't no such thing as child=proof anything. I used to call one of my babies the "finder of all lost things" because he would get into places that no normal human could be and come back with stuff I thought was lost long ago. The best way to protect your rig is to protect your baby -- whatever it takes, whatever it takes!!
I converted from Maggies to Martin Logans once my kids became mobile. I wasn't as happy with the sound, but the speakers were indestructible. Once they are old enough (around 5) you can go back to anything you'd like. Now, my 14 year old is cautious enough that I let him use my system, and he's very careful with his own table and system.

I did the same thing when I had Watt Puppies with child gates,

The only child proof speakers are electrostats as the drivers are protected by stators which are usually stamped from metal.

The only issue then becomes the panels may look really attractive to getting small objects pushed into them.

I would recommend the new Janszen ZA 2.1 unfortunately they cost $7.5k but the sound quality is amazing! I just got a pair and in many ways they sound more like $15-20k, they are very sturdy and nearly indestructible, and the drivers are nicely hidden by non removable grills so there is no chance of little hands mashing up drivers.

Call up Janszen and see if you can get a pair to hear they are really remarkable speakers.
The most child proof speakers I know of are the Yamaha NS1000 monitors. All three drivers have strong cages. You can get them used for @$1000 on up. They are now a "cult speaker" and extremely loved by those that love them. They may not be exactly what you want but they will survive anything that is not thermonuclear.
I had the same concerns with my 3 children. It turned out that teaching them to respect "Daddy's stereo" was the easy part. Their curious friends and playmates are the ones to look out for. My best advice would be to prepare yourself mentally that everything will get broken or damaged. That way when it does, it's not so upsetting.
