View Full Version : Filling Speaker Stands With Concrete

I need ideas for filling up the speaker stands I just made. I don't particularly want to use sand because I'm afraid it will eventually vibrate out and make a mess. Would concrete be a good alternative? I happen to have several bags just lying around.

Even though I have no idea about the realities of using concrete, it doesn't sound like a good idea to me (just MO). Why don't you just caulk the inside before putting sand in. Or put the sand in some sort of bag that is inside?

Using bags is a great idea.
Alternatively, are you set on filling the stands? Are they too light or vibrate too much if they are left as-is?

Using premix concrete is dead simple, but permanent. You would probably want to make sure any joints are sealed so that you don't get water and concrete power seeping out and staining the outside of your stand.

I got the idea from someone who has done this before. He told me that sand would just leak out.
However, the bag idea sounds interesting.

I just googled this, so:
Concrete is around 140lbs\cubic foot
Sand is around 100lbs\cubic foot

In terms of sound would there be any effect that way,I feel as if concrete would bounce/echo and sand would absorb/trap is this right, sorta.:confused:

I vote for sand in a bag. Just make sure it is well washed and dried, or you have a terrible problem.

You can also use fine lead shot. It can be obtain from any shotgun reloading supply company. The larger the shot number, the smaller the diameter.

Concrete just doesn't sound like a winner to me. Going to have to say pouring anything wet into your stands is really not the best idea.
Sand dampens the vibration because it is LOOSE. As long as you seal the stands properly, there is no reason why sand would leak out.

How about the fine small tumbled rocks used in fish tanks it wont escape through any cracks in the base.
I know then we could add fish :rolleyes: I'll say first :)

The rocks will rattle IMO. Exposed lead in your living areas is probably not a good idea either. I was thinking BBs.

Lead shot is what was recommended to fill my speaker stands with by the manufacturer.

I think my last two post were kinda J/K around some , in all seriousness I like the sand idea maybe use some thin liner to keep it clean but a bead of caulk at all seems would surely do the trick also.

Sand may not be as dense, but it is a lot cheaper and less toxic than lead!

Most shot sold today is either plated lead (nickel or copper) or made of other metals, like steel. Besides, it would be sealed up inside the stand. It's not like you'll be licking up the extra pellets off the counter. (Well, I wouldn't.)
In the half dozen or so stands I've had for small speakers, sand has never leaked out. Good point earlier about it being clean and dry. Sandblasting shot is a bit more exensive (garnet down here) but it will be clean.
Lead shot is fine too, and is non toxic so long as you don't eat it.
Concrete filling will require sealing the insides if they are wood or the moisture whilst drying may affect the wood.
OK, I wouldnt use old batteries either,lol!
Absolutely no concrete as the lime will over time, leech through wood,well unless you have a woodpecker problem?
I think the weight at the bottom, bird shot,above that insulation like polyester pillow foam stuffed tight,so foam first,no 9 birdshot,sealed at bottom with clear dercon epoxy ! ta da done!
Sand seems to find away to migrate, adding vibration helps that!
Make this baby bottom heavy as can be!
A turntable vibration problem was solved by one fellow using a 40lb bag of white sand and a little wood box, if it werent for the beachbum mouse he would be a little happier person now! Really was a great turntable too,shame!
YEP this was war,couldnt have been pretty!
