Something pretty thick on the rear - at least 6" and at least 2 2x4' panels.

For your side walls you'll want more surface area and thicker. Again 2 2x4's each side and at least 4" thick with a bit of a gap behind them.
I'm sorry, i dont get it, maybe its becouse im dutch and there is some misscomunication, but you where speaking here about 2 panels on the left side and 2 panels on the right side, correct ?

Do i need the second panel on the same side to mount right next to it, above it, or would there be another way to check where to place? for as far i could check there is not a second reflection point on the same wall to find with the mirror technique.

Yes - 2 on each side wall forming essentially a 4x4' square. Same thing in the rear but 6" thick instead of 4"

I am serious... and don't call me Shirley.

Re: 100 hz dip

Wow, now i'm really getting confused.

I think its because of the differences in how you are used to describing measurements in the US. It's diffrent in Europe.
Though i thought i understood. So essentially this is what your talking about ? (check pic)

I thought all this time you where talking about feet. like 2 feet by 4 feet when talking about 2x4' which would be panels from 1.20 by 60 cm converted into European standards.



But if im understanding you right this time you meant with 2 2x4's pannels 4 pannels from 4 ft by 4 ft each ? which would be 4 times 1.20 meter to form a square.
Thats impossible, that would be a square of 2.50 meters by 2.50 meters. Thats huge for this room. Where am i going wrong here in my calculations ?

Thanks for your patience by the way

No. You're right. 2x4' panels. 2 each side.

Re: 100 hz dip

Oh! Oke. I will try to get it to work then. So correct me if i'm wrong but 2x4' times 2 in the form of a square is just the same as 4x4' in a square right ? this must really sound silly but for a European that's really confusing to say it like that. But im glad i'm understanding now ). So i guess the gaps you where talking about where based then on in between the 4 and not behind the panels right ?

Re: 100 hz dip

Yes - sorry to be confusing. The air gaps are between the wall and the panel to get the front of the panel farther from the wall.

Re: 100 hz dip

No that's not on you, that's more my understanding of U.S measurements i guess .

Yes I know the air gaps are between the wall and the panel. But are there supposed to be gaps between the 4 panels as well ?

For example when you say : "At least 4" thick with a 4" gap." Then are you talking about a air gap or a gap between the 4 panels like the picture above ?

No. We're talking about the gap between the panel and the wall.

Man, im sorry, but i am still not sure if i am understanding this right. last time i was sketching two situations at which your response was, yes you are right.. but which situation was right i am now wondering ?

As you can see in the quote your saying 2 on each side wall forming a 4x4' square.

So when talking about 2x4' are you talking about the size of the panel ? (2 feet by 4 feet) or are you talking about the amount of panels ? 2 TIMES 4' panels (so 2 panels of 4ft by 4 ft) . which would take 8 panels per side in total to get 2 squares. This makes a huge difference
