Brilliant!

That's actually kind of what I was thinking about doing, Mark...

You guys stole my idea! Only I was thinking of an actual full base not out riggers. A solid piece of wood that could be have routered edges and stained to match the speaker finish.

I had contemplated bolting the M22 to the top of the M60 using the threaded inserts to prevent the M22 from falling off the top if bumped into.

Jeez! I like the idea, but completely smashing the M80 above the bottom woofer is uncalled for. The speaker is more dangerous than ever with those jagged shards of wood now.

Hence, not needing the moat, alligators, razor wire, etc.....

If your toddler is anything like my 14 yo was after he started walking, it won't be long before your speakers are on their side, or on top of your kid. And while I'm thinking about my boy in his younger days, if you have a cat (and cat box), you should plan to keep it somewhere the kid can't get to it now, before it's too late. I’m still scared from seeing that sight….and there was that medicinal smelling “cookie” he found in the men’s bathroom….. OMG…. No more kids for me. Good luck Ken.

All you need to do is spread the footprint of the speakers about two inches out in four opposite directions. Two inches will triple (or more) the resistance needed to tip them over.

Heh... the cats/cat boxes will be quite an issue, I suspect. OK, guess i get to go to the hardware store and look at pieces of metal or something.

OK, lets see if adding 4 inches on each side of the speaker 'base' will help prevent tipping... ( I don't think 2" would be sufficient)

Here are my assumptions:
you have M80's with carpet spikes so sliding is not considered
Tipping sideways is considered since it will be easiest to tip that way.
The average 2 yr old boy is 3 ft (link), so lets assume they are pushing or pulling 2.5 ft off of the ground.

Here are my results:

As is:
A force of 8.99 pounds will be required to tip the speaker when pushing horizontally on to the speaker 2.5 ft from the ground

With an additional 4" of 'base' added to the bottom:
A force of 16.57 pounds will be required to tip the speaker when pushing horizontally on to the speaker 2.5 ft from the ground.

Conclusion:
a base increased by 4" on all four sides will require about 1.8 times the force to push/pull it over.


Next we can calculate the force the speaker must withstand in order to resist tipping due to the momentum of a toddler in full sprint...

do you think a 2 yr old running down the hall and hitting a speaker at full sprint will impact the speaker with a force greater than 16.57 pounds?

I say we need more than a 4" base

perhaps the shock collar isn't such a bad idea after all!

Perhaps I should post pics of my living room...



Now, this isn't quite accurate any more, not the M50s. Everything is shifted to the left by about a foot, so the M80s are right up next to the bookshelves, and I've got some stuff stacked in the right corner. So it would be hard for him to tip them completely over; it's more likely that he'd tip them enough to knock over the bookshelves on his head.

I think your calculations are in error. Please show your math. This is a test..... (don't forget centerline moment) I’ll verify your math with Autocad. just kiddin...

Ken, if it were me, I'd pick up some 3/4" X 2" X whatever length you need oak boards. Drill holes through the boards that you can run some screws through. Mount them to the speaker and place the rubber feet under the ends of the boards. Move the feet in / out from center and experiment with tipping force. After you get the lengths figured out, remove the boards, cut to length and put whatever edge profile on them you like (whatever router bit you might have). Then stain / finish however you want.
