Acoustic Slat wall panels columns as corner bass traps?

[ripmixburn]

Hi all,

Has anyone experimented with turning the newer wood-veneered MDF slat acoustic panels with PET backing into column-shaped corner bass traps?

These panels are cheap, widely available, and many use a flexible PET felt layer that bends easily. Because they come in 24-inch widths and full ceiling-height lengths, you can form cylinders like:

• Two panels curved together → ~15.3" diameter column
• Three panels → ~23" diameter column

Placed in corners and filled with mineral wool or fiberglass, these should behave like large cylindrical bass traps—strong LF absorption—while the slatted exterior provides some HF scattering instead of overdamping the room.

The idea is basically a hybrid trap: deep cylindrical absorber in the corner + slatted face for more controlled mids/highs.

Has anyone actually built these, measured them, or seen them tested? Curious how LF performance compares to a standard stuffed corner tube trap and whether the slats change anything meaningful in the mid/high range.

Would appreciate your thoughts.

Some quick AI generated mockups

is the backing porous enough that the sound isn't reflected and bass wave can be absorbed? I know many of the larger bass traps and reflectors etc have "acoustic" fabric for that purpose. Seems like a great idea.

Gik has something similar.

I will likely go the "quarter round" route for aesthetic and cost purposes, though I'm not final on construction yet. I have at least one additional corner in the room I can use, so I'm looking forward to this. It's strange how these slat panels were rare a decade ago and now are everywhere.

report your progress as you go. Seems very interesting.

Wood acoustic diffusers have become a decorative item - loved the idea!

Lightweight skyline diffusers made of expanded polystyrene than can be suspended using hook and loop (Velcro).... http://www.rpgeurope.com/products/product/skyline.html They created the diffuser type Skyline which is now a standard term. They have been around since the turn of the century...

In progress still but someone beat me to it… https://www.facebook.com/share/p/1bMSFkDD4X/?mibextid=wwXIfr
