Related to my other thread ..

I am building a room and wondered if a single sheet of drywall can be bad. I mean can you have strange interactions with the walls when funing four of S/.HO 18's as an example? If so I can just run up another sheet of drywall..and some damping compound.

MIght be a silly question but I figured it coudnt hurt to ask.


Thanks.

Unless you build a concrete bunker 100 feet below the foundation of your house, you will never remove the tactile earth shaking bass 4 18's will create...

I lifted the screws loose on the sheet directly above my subs in my old theater that only had single layer, and it rattled loudly enough that I thought I broke the projector screen mounts.

I now run triple layer with greenglue and haven't had a structural problem yet (6 months).

It all depends how silent and low of a noise floor you want. Once bass starts rolling you start hearing the room cry uncle and if you don't want to hear that then you need some help.

Just out of curiosity... how far away from your neighbors are you?

When I built my first 18" sealed Avalanche I connected it to my living room setup and my friend brought over a bass testing CD and we gave it all we could. half hour later my neighbor called me telling me I knocked down all of the China in her dining room. Her house was 30ft away from my closest wall...

I say they were full of crap. I bet they just blamed you. I run loud bass and my neighbors never complain. Even in my concrete basement you can hear bass around my house. I have 1.07 acres though but they are closer on the sides. The closest neighbor must be 50 feet or more(their house not land). I have broken lights, marble, door handles, molding, I have knocked down my acoustic panels and pots and pans out the cabinets upstairs.

Typically your neighbors won't even notice the bass during movies, it's the rhythmic thump of music the irritates people.

Oppo 103D
Samsung pn64f8500
Pioneer vsx-82txs
And a bunch of DIY speakers and subs.

Out of Curiosity What "help have you guys gotten.. Do you have Decoupled walls. or 2 layers GG/ 5/8th Drywall? What has worked for you?

And in my case The closest neighbors house is about 300 ft. So no issue there. And the living areas are separated from my theater room by the garage. The theater is connected to the house by only one wall and that wall is shared with the garage. the attic the theater shares only with the garage so sound isolation from my family or neighbors is not an issue. Its just a matter of not wanting my room to be detrimental to the sound system..

I have a single layer of drywall, but it is glued and screwed to 6" studs. Drywall does not make noises in my room. Two SI-18's, One Mal-X 18 and two TC Sounds 12's. Soon to add a couple TD18H+ drivers.

All the above! The best way to sound proof a room is to build a room within a room with gaps or air space in between. Concrete will keep in bass but how many have concrete ceilings! I have soundboard, drywall, more sound board, heavy insulation, and concrete outerwalls. The inner walls and ceilings are what I said. I never used GG.
