3D printed gyroids for acoustic dampening

Alright.

I want to 3d print a compact transmission line (tl) speaker for my friend. For the bass cabinet I wanted to experiment with a 3d printed tl.

Now if I understood it correctly, dampening a tl is really important to reduce high(er) frequency resonancies that happen normal to the center line of the tl tube.

A lot of stuff like shifting and inhomogeneous density of the dampening materials makes kind of a hit or miss.

Gyroids have maximal area per volume and their internal shape makes for an interesting opportunity in dampening, especially with a linear decrease in hole size depending on the distance to the center line.

Plus 3d printing makes homogenous dampening manufacturing really simple.

Tldr: 3d printed gyroids as acoustic dampening material especially in transmission lines to make more homogenous dampening.

Please tell me honestly what you think. I have to yet try it out/simulate it in akabak.

Looking forward to your input :3
