So if i aim for sheets of 900X2800 fabric for each panel?

How did you go about working out the fabric sizes?

I will be likely going to the same spotlight store you did (belrose) so hopefully i can easily find similar to what you did.

I calculated how much fabric we'd need based on an extra 150mm for each side (100mm to get to the back, and 50mm to be stapled to the frame, although you may need more if your frame is thicker). Your aim of 900x2800mm for each panel is fine. The fabric we got came in a width of 900mm, so you can easily get it cut to the length you need.

Just wondering, are you planning seven floor-to-ceiling panels? Except for your corner traps, they probably don't need to be that big.

Well my room is very lively...Wood floors) so the more absorption in here i can get the better

I have no way to attach roof panels so i figure if i keep most of my panels near the roof it will help.

So the idea is 4 corner panels.. (one is at the door but i can move it back and forth)

2 side panels (same height) for early reflections and more bass trapping (since its against the wall) and a panel at the back of the room.

My mix position faces a window but it has a large roller blinds. I am thinking of filling the window in with the acoustisorb (temporary only as i am renting) Also i have about a metre or so of floor space between my mix position and the window which i was thinking of puttiong some acoustisorb on the floor.
Since this is all movable stuff i can experiment and do various sweep tests and see what comes up best.

Why would it be an issue to have larger panels anyway?

for the corner traps i am thinking of doubling up on the acoustisorb (since i have 2 packs coming). So have 2 layers on the frame (200mm) would this be better as a bass trap or not?

Not really an issue, just a bit unnecessary, but if you can spare the material then go for it.

Doubling up should definitely help, unless anyone else can think of a reason why not. You'll probably need a stronger frame than the ones we built, though.

Hmm i tried to make a new thread to specifically ask about doubling up the acoustisorb 100mm to make 200mm panel traps...but it did not seem to post.

Wanting to know if it will actually work better or can it be worse? i have read some mentions of traps becoming less effective if too thick.

Well i got my delivery yesterday! I decided to use the reflection panels without frames as it stands up ok. But my landlord has helped me build very good sturdy frames for the 3 bass traps, which each will have 200mm of the insulation!

Even with the front/back and side reflection panels my room is sounding so much better! Love the detail i can hear in the panning!

Still bass issues but im sure the corner traps will tame them well.

I have built in wardrobes in my room i think may be causing bass issues too so i may need to find material to help fill them in some to get better bass absorption.

Also for those cutting the acoustisorb...try using an angle grinder with a large steel cutting blade...worker very well for me...Using a knife or anything like that is very hard....But the angle grinder gets a very clean and easy cut!

Sounds good, make sure to post some pictures when you're done!

Done for now 3 bass traps with frames...pics of completed products plus just the frames. My landlord luckily has power tools that made it all easy.











Photos to come later with them in my studio space. Still having some issues at around 100-120hz but the peaks are much more under control now.

Looking very nice! Much neater than the ones my brother and I put together (if only we had an iota of practical experience and power tools beyond a drill...). Looking forward to seeing them in place.
