Bass trap + reflection point panels - small studio design

[Cian Murphy]

Hi, long time lurker first time poster here... first off, I've had some great help here with regards to construction and design without even have to post, but there comes a time when you must bite the bullet! So, I have this small room:


I came up with a design using 6 bass traps and 3 reflection panels. The bass traps are 4 inches/10cm, using knauf rock silk 140kg/m floor slabs. Pretty heavy, but the best i could get here in Sweden. the reflection points are 2in/5cm panels with the same materials. Here's my initial design, with additional furniture:

Perspective


I can think of some potential problems with this, and hope you can help. First, the right reflection panel is pinned behind a desk. Does this reduce the effectiveness? can I get away with positioning it higher? The left reflection panel is on a door, so i can mirror it but cant go too high. The left corner trap nearest the mix position cant be positioned at 45 degree angles, more like 60/30 angles. Is this ok? If so should i place the right one at the same angle? In the rear left corner, I have two wall mounted bass traps with a bookshelf right infront of them, is this bad? the book shelf goes almost to the roof.

I have everything built, just need to mount them. not looking forward to the roof mount! As far as i know, the right wall is concrete, the left dry wall and the ceiling might be concrete too!

No your fine.

Sure but make the other as high.

That should be ok

If so should i place the right one at the same angle?

You might be fine. If you want to make sure try it both ways and test the room.

In the rear left corner, I have two wall mounted bass traps with a bookshelf right infront of them, is this bad? the book shelf goes almost to the roof.

That is fine also.

Very prompt, and very reassuring. Thanks Glenn. As soon as i finish it I will post pics and test results, assuming I can find an omni directional mic using broken swedish.

Looking forward to the pictures.
