Getting more out of your back wall diffuser array with a simple hanging DIY array/bass trap.

的一大“墙”问题人我s “If I have a large diffuser array, how can I get the bass trapping I need?” A great answer to this question is to turn the entire array into a hanging bass absorber. If you are already planning on getting diffusion for your back wall, here is a great way to use that wall space for more than just diffusion.

Stuff you need:

• 4’x 8’ sheet of 3/4” Plywood
• 32 sq/ft of 4”Cutting Wedge® Classic Foam(Or similar absorber)
• 8 xArt Diffusers®–Model C(orModel F,Quadrapyramid™, or other comparablediffuser)
• 2 xIsoHangers
• 2 x Heavy rings (Think big Curtain Rings or Hanging Wire will also work)
• 2x Closet Rod/Shelf Brackets
• 2 x 7/8” wood screws and fender washers
• Construction Adhesive (Make sure it’s safe for Foam)

Assembly instructions

• Screw the twoIsoHangersto the plywood, using a fender washer on each screw. These should be about an inch in from each end -drill small pilot holes first. (These will be used to hang the panel, this side will be designated as the back from here on out.)
• Use Construction adhesive to attach theCutting Wedge® Foamto the back of the panel in a checkerboard pattern (each panel 90° rotated from adjacent)
• Use Construction adhesive again to attach the 8Diffusersto the front of the Plywood (Follow the installation instructions for adhesive placement)
• Attach the Rings or Wire to the free end of theIsoHangers.

What you have created is a hanging panel that will diffuse mid-high frequencies and trap the lows. The hanging mass absorbs low frequency energy by moving slightly when pushed by the energy of the Low frequency Waves. The rear facing fiberglass also absorbs low frequencies by dampening the panel, but it also absorbs any of the waves that happen to get trapped behind the panel.

Hanging the Diffuser/Trap Assembly

• Measure and attach the Closet Brackets to the Wall – Use appropriate anchors! If you have standard or double wall constructionwithoutResilient Channels, use the studs – TheIsoHangerswill keep vibrations from transmitting through the wall.
• Hang the panel on the Closet Brackets using the rings/wire with theDiffusersfacing you and that’s it!

A little History…

If you embark on this little construction project, you will be constructing studio elements that have remained basically unchanged since at least the early 1970’s. Hanging plywood wrapped in studio foam or fiberglass has been used “behind the curtains” of many of the top studios for effective bass control for over 40 years – just no one has ever seen it, as it has been hidden in walls; masked as a false wall of fabric stretched across wooden louvers!
