Axiom Home Page Forums General Discussion Home Theater QS8 ceiling mounted with Omnimount 20. Drywall OK?

Auggh. I wouldn't use anchors on the ceiling, even really high quality anchors installed perfectly. If the joists aren't in the right place then run a nicely finished piece of wood between the joists and hang the QS8 from the wood.

>>or is drywall strong enough to take both the static and dynamic loads?

I should also offer the non-engineer's view (not mine, but I had to learn it over the years) -- if it takes more time to work out the loads than it does to patch the drywall, just hang 'em from the drywall and don't stand under them for a few days until you know if they're going to fall down

EZ Anchors are not designed for ceiling applications where the load is pulling directly away from the drywall.

For safety attach them directly to a cieling joist.

That is a good thought John, Beth could take a nice stained piece of wood and attach that to the joists, then attach the speakers where she wants them...

Beth, can you provide any pics?

I got the idea from Mark, with his "QS8 plaques".

>>I just got my Omnimount Ceiling 20 brackets and am about to hang my QS8s. The mounting instructions show the installation for drywall in detail

Beth, I just noticed this. Are you saying that the instructsion cover mounting directly into the *ceiling* drywall ? Is there any chance those are generic instructions covering both wall and ceiling brackets ?

Do you have an attic?

You could always run a 2X4 between the joists in the attic, then mount the QS8's into the 2x4.

Similar to bridgeman's idea but have the wood in the attic instead of on the ceiling.

If you do this I would make sure that you drill into the 2" side of the wood (so the screw has 4" of wood to 'bite' into.) Not to mention the reduced deflection and higher moment of inertia when the 2x4 is bent about that axis. The tricky part would be placing the wood exactly where you want the speaker... you could poke a hole up from the ceiling and stick a wire hanger through to see where to place the 2x4 in the attic.

bridgeman,
Here is the link to the omnimount page:

The 'installation instructions' pdf talks about drywall installation, but it shows a picture of a wall at the part so I do not know if drywall ceiling mounting is ok.


On a side note, My audio pier is made by omnimount, here is the picture:



It is a VERY sturdy piece of furniture.

It says it is rated at 50 lb per shelf, but It definitely feels sturdy enough to support someone standing on it.

Oh really?

How about "EZ Anchors are not designed for ceiling applications where a *heavy* load is pulling directly away from the drywall" ?

I think I have an experiment to do with some old drywall I have, my EZ Anchor assortment and my free weights..........

Most ceiling drywall is 3/4" with 16" on center studs, should work just fine, not saying I would do it though. I'm sure the 12 gauge wire would keep the Q's from falling to the floor.
