Ceiling sound proofing Options?

Hi,
I already have resilient channel bought for my basement games/theatre room ceiling. After reading a bit more here I wonder if It would be better to use two layers of dry wall (1/2 and 5/8) and green glue? or a combination of two layers and the channel? I'm not sure if the channel will support two layers? If I put up 5/8" drywall followed by a 1/2" on the channels will I make things worse? What if the space were filled with insulation?

Whats my best option? I'm not concerned about not using the channel as I'm sure I'll find use for it somewhere else?

Thanks!

Re: Ceiling sound proofing Options?

I'm sure the RC people can answer the weight bearing question. But you need mass to stop low frequencies and double drywall is the best way. Actually double QuietRock is best but that is outside of most budgets. Insulation does absolutely nothing to stop bass. I know, my theater room walls have insulation in them.

I wonder if doing a single layer of drywall and then attaching a seconld layer to that with the RC would be effective?
