No. The dual drywall and drywall isolation systems available don’t help with in-room reverberation. You will need to add absorption and diffusion in the room to get it sounding awesome.

If you are into DIY you can also use 1” roll fiberglass materials like duct liner and 1” batten boards applied to the existing drywall surface, all covered with acoustic fabrics from Guildford of Maine. I did this with my last dedicated theater to good effect.

You might send your room size and layout info to GIK Acoustics or another acoustics company and see what they recommend. If I were to do it again this is what I’d do because it is easier and you can add treatment incrementally. Getting the low frequency reverberation tamed is the most difficult part.

Good luck!
