Extrastrong: Soundboard comes in 4x8 sheets and supposedly helps damp sound more than an extra layer of sheetrock. From what I gather it appears just an extra layer of sheetrock would be fine although is about the same price if I remember correctly. You need to use sheetrock for ceilings, can't remember what it's called, so it can't sag.
Resilient channel can also be purchased at a construction supplier, not Home Depot or Lowes though at least here.
You'll have to see it to understand but you screw the sheetrock to it and the sheetrock actually hangs from it allowing the sheetrock to vibrate without vibrating the rafters much. It's cheap and well worth it.
I have two systems down here in the basement. With my little system in my computer room the sound goes straight through the floor. In my big system I can crank it and you can hear some bass but that's about it. With the small system I have to keep it turned down! My main speakers outweigh my little ones by 240lbs a piece.
You can email me if you need any more help. You'll be very glad you did this.
