RE: No trains, but you can feel a truck go by on the highway 600 feet away. It's an old 20s Sears house.

If you can get to the basement, I might damp the floor -
there are a couple of ways - cut up blue board (an acoustically dead drywall product)and secure it to the sub floor - liquid nails...
then cross brace the joists or add a sheet of ply + drywall to the bottoms of the joists to damp the bottom edge of the joists...

I would think that if the speakers can generate decent LF signal, it might cause the sand to move around, and if you 'floated' the speaker, could cause the float to drop and push the sand out of the box...

Happy listening

You better have a really good suspended floor - rickmcinnis@dogwoodfabrics.com 20:33:07 07/22/12 (2)

Well, 12' by 3' at six inches would be 1,800 pounds of dry sand or 50 pounds per square foot. - cfb 05:31:11 07/23/12 (1)

If you feel good about it I think it is a brilliant idea - rickmcinnis@dogwoodfabrics.com 09:41:17 07/23/12 (0)
