Thoughts on using sand as a filler in an enclosure.

[cobra133 10+ year member]

Ok, here is what I want to do. I have two mtx thunder 6000 12" subs. I want to wire them in a custom built enclosure (I'm making this) and then make one side of the enclosure either 3/4" or 1" plexiglass for a window. Heres the trick. I want to make an enclosure that is about 2- 2 1/2 time the size that mtx recommends. The enclosure will be very tall and narrow. I want to fill the extra volume up with sand. I've heard of this being done before. It is supposed to completely deaden the enclosure and prevent rattles from occuring. This happens because the sand is really absorbant because of its mass. ANy thoughts?

I wouldn't recommend it because if any sand finds its way to the voice coil or into the pole your woofer is going to be screwed.

Hmm... I'm not sure if it would. I think the woofers would be about 2 feet away from the sand. I could also make a barrier with speaker grill cloth to prevent any sand from getting in. In fact, i think i will do that. thanks for the advice.

with the pressure inside the box i would imagine you would have an actual western sand storm in your box.

Hmm... i think you are right about that sand storm. None the less. i can't help but feel it would truly deaden the enclosure.

Any ideas on how to make this idea work?

Are you talking hardened concrete?

you want the sand to just sit and not move ? u can mix the sand with a combo of water + glue mixed together and when it dries , wallaaaaaa

 

[cobra133 10+ year member]

Actually, I kind of want it to move around. The thing is, i dont want any sand to get in the woofers.

for a school project you can do a re-creation of the great american dust bowl.

Use stacked pieces of 1" MDF. 2 or 3 inch thick walls will not flex.

How about simply...why are you making it bigger than is needs to be? why are you looking to use sand....why not just make it the right size?
