I'm starting construction on my theater very soon. I will be building a stage to place my speakers/subs on and wanted some advice on how to deaden the stage. I've seen a build where sand was used. My home is 90 years old and this seems like to much weight to put on the floor since the theater is above the basement. I'll be using 2x6s for the stage joists, would partially filling the spaces still be useful? What about a combination of sand with a lighter "filler", say lava rock or packing peanuts?
Thanks for the help
