Getting more out of your back wall diffuser array with a simple hanging DIY array/bass trap.
One of the big “back wall” questions people have is “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 x Art Diffusers® – Model C (or Model F, Quadrapyramid™, or other comparable diffuser)
- 2 x IsoHangers
- 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 two IsoHangers to 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 the Cutting Wedge® Foam to the back of the panel in a checkerboard pattern (each panel 90° rotated from adjacent)
- Use Construction adhesive again to attach the 8 Diffusers to the front of the Plywood (Follow the installation instructions for adhesive placement)
- Attach the Rings or Wire to the free end of the IsoHangers.
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 construction without Resilient Channels, use the studs – The IsoHangers will keep vibrations from transmitting through the wall.
- Hang the panel on the Closet Brackets using the rings/wire with the Diffusers facing you and that’s it!

For those customers who are planning on purchasing diffusers to make an array, or maybe already have an array and are looking to try a new configuration – this project may be what you’re looking for.
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!

DIY: How to quiet down that noisy equipment rack

Take a few seconds and DIY fix some of the common problems with using equipment racks!
Not too many people think about their equipment racks, but many of us use them. Usually it’s something like what you see to the right – the great, sturdy, utilitarian box. Unfortunately, there are a couple inherent problems with these:
- Ringing – The metal resonates causing a ringing effect – may be masked by program material.
- Reflections – many times your rack is near sound sources causing reflections off the hard surfaces.
- Noise – Fans and other devices in the rack can make noises that are disruptive to recording.
Here are a few DIY fixes for these common problems.
- Composite foam with adhesive backing is perfect for stopping the ringing of filler panels.
- FireFlex™ acoustical foam the inside of your rack to keep the noise down.

- Use some Composite Foam to line your trays, drawers and shelves to keep items from rattling around inside the case.
- Cover your rack in Sound Channels® fabric to keep the case from causing harsh reflections.
- Make a temporary cover for the front and back with BlockAid® sound barrier with minimal ventilation cut-outs to use during takes if rack-borne noise is problematic.

DIY: Isolation Stand for Speakers and Instrument Amplifiers

DIY Project – Float your Loudspeakers and Monitors
Keep your Amps and Monitors from shaking the house down!
Instrument amplifiers, loudspeakers, and studio monitors all have the potential to cause structural vibrations. These vibrations can have an adverse effect on the listening environments, and can bleed into other microphones and instruments. Here’s an easy DIY project for floating those noisy guitar and bass cabinets (this project can be scaled up or down – from studio monitors to subwoofers).
Stuff you will need:
- 2 – 2’x2’x3/4” Plywood (whatever size you want)
- 2’x2’ Carpet Underlayment (Same size as Plywood)
- 2”x4”x8’ Lumber for frame (More if scaling larger)
- About 1 cu.ft. Clean Dry Sand (Sandbox Sand)
- 3’x3’ Industrial Carpet (Enough to cover platform)
- Vib-X Pad to cut at least 4 – 2” Squares for feet
- Construction Adhesive
Simple assembly
- Create Frame and attach to bottom Plywood
- Attach Vib-X feet to bottom
- Fill with Sand
- Attach Plywood top
- Adhere Carpet Underlayment to top
- Carpet Box
This plan is for a 2’x2’ platform. You can scale these or use more than one. Scale with caution – the sand makes these extremely heavy. What you are building is a floating platform. Keeping the sound from being transmitted into the floor below effectively decouples the speaker, making it “float”. In essence, the vibrations are being absorbed before getting to a solid surface, allowing for a more transparent listening experience and keeping the vibrations from interfering with other instruments in the area.
