I have an acoustics specific question from my original post in the construction forum.
I will be installing some drywall hangers this week. Each drywall panel is 12.5mm thick, and 1.2m by 2.4m.John Sayers wrote:Just use 12mm plaster sheet javier - that will work.
I was thinking of initially purchasing three panels, to make 6 hangers of 0.6m by 2.4m and covering them with 2.5 thick insulation (21.6 kg/m2 dense).
The hangers will have a total thickness of 17.5 mm, each drywall panel will have a wooden attachment to the top of it to make the drywall not break from the hanging mechanism.
The will be separated by 2 cm from each-other and the insulation on the wall. Angled about 8 degrees towards the speakers.
The corner behind the waveguides will have 5cm of insulation (should i got for more?).
See how that changes the low end response. If they work I would build four more hangers to a total of four in each rear corner.
I will compare the results with REW, before and after.
I'm thinking three panels on each side will not generate much of a difference in low end response. Do y'all think this will be worth the try? This drywall version is fairly less expensive than the cork board alternative.
