Hi,

Do you know where I can find info about gobos and how to build them??. What kind of material I might use, what size??. I´m looking forward to build one and use it for drums and vocal isolation, is this possible.


Thanks in advance

Here is an idea, you could probably scale it for your purposes.

Great!!. Now, could you help me with the details??. For example, what kind of material is recommended for the main structure. Can I use foam instead of fibreglass?. How I cover those holes?? Using slots of plywood??. Please, tell me more about the materials.

Thanks

Well the slots are 1 x's and the main structure looks like 2x8's to me.

And Fibreglass is what you want to use, not foam. it has a higer absorption Coefficient than foan (acoustical foam)

I played with foam and ended up using fibreglass. Waste of money and time to experiment.

The materials are listed in the diagrams. Read carefully and follow the diagram
