DIY Acoustic Panel Build Plans

[vc_single_image image=”77572″ img_size=”full” alignment=”center”]

With our DIY Acoustic Panels you will have a functioning piece of acoustical furniture for your home theater, personal listening room, or professional recording studio.

You will be able to create a piece of furniture that has a real wood stain to match the wood stain and finish on your speakers.

The foam of your choice goes into the box and an acoustically transparent fabric goes across the face. Acoustic Fields can provide you with foam pre-cut to fit your box and the acoustically transparent fabric which is available in over 38 different colors.

We have three thicknesses you can choose from depending on your sound absorption requirements. Our foams go from 125 Hz. – 7,500 Hz.
