Gobo Fabric Covering

[Glenn Kuras]

Burlap will work fine and only if you BEAT on it with a bat will fibers come out. The best fabric is Guilford of Maine.

Thanks so much for the reply Glenn.

Can you also answer me this:

In what situations would you need to face any acoustical panels with FSK Foil?

FRK and FSK facings are for corner bass traps. Panels at reflection points, and on the rear wall of a small room, should not have the facing. It's that simple.

Hey, Ethan and Glenn:

I assume FSK for corner bass traps is to reflect mids and highs off your traps. I am wondering if you can economize on the number of thin panels you need for mids and highs if you allow the bass traps to absorb some mids and highs (i.e., no FSK), or is that a no-no?

Thanks

The number of panels depends on the room. Every room will be different. I would recommend covering the important points like early reflection points (What Are Early Reflection Points. SPOTLIGHT:Bob Ebeling - Revolution Studio) and back wall (actually you want thick panels for the back wall) and see how the room sounds. At that point you can place panels on the back side walls (or diffusion) and ceiling to help over all decay and flutter echo.

While I've got your attention can you answer me 2 more questions?

1) When using FSK, does it only have to be on the most outer panel? Or should you layer say a 6" deep panel with 3 2" FSK faced panels? (Sorry if this is a silly question)

2) After watching the "hanging a corner panel" video on GIK Acoustics website, I noticed the panel was hung in the center rather then closer to the floor or ceiling.

Is it better to place your bass trap corner panels closer to the ceiling or is center prefered? I always assumed leaving the corner where the walls meet the ceiling open was a no no.

Thanks again.

You only want th FSK on the face of the panel. NOT in the middle or back.

Bass is going to pick up in all of the corner. Tri corners do pick up a bit more bass but it is not critical to put the trap there, as sometimes in the front of the room having it in the middle will help with SBIR (What is SBIR?). Honestly though covering from floor to ceiling is always best.

Hey guy's thanks so much for all your replies really I'd be so lost without this forum.

Can you tell me which is best or any reasons why you would use FSK over FRK with corner bass traps?

I believe they work about the same.
