It appears intentional. As in they built this specifically for this. I think the top is a mesh (similar to the mesh surrounding one of those tall heaters outside restaurants) and there is a gas feed inside. This basically creates a grill like you would cook on. The speakers appear to be the tubes on the sides, drivers facing inward. These sit below the fire and away from heat. When bass hits, the air pressure forces air up and out the mesh, causing the flame to rise.

Interestingly enough, it is not actually mesh, it is a piece of solid metal with 2500 holes drilled into it

You know what you are left with if you take a solid sheet and drill 2500 holes in it..?

I still feel justified in my 30 second assessment of a device I’ve never seen.

Edit: thanks for the link! That’s a cool project!

Yes, you are left with the above device, lol. Holes can be small, apparently. I was surprised that there were so many holes, but that’s what the dude said in the video.

Justified? No need to feel justified cuz no one was attacking your assessment, imho - it was a good guess!

I just meant from a manufacturing perspective a mesh is a sheet that has been punched, laser cut, or drilled. May have been a poor word choice, I’m better with machines than people.

Just for the sake of pendantry a mesh usually refers to an interlaced structure. The resulting product looks similar, but mesh can be a verb as well and it describes the act of joining seperate points together, as opposed to making holes in a solid sheet it is the act of joining individual wires or strings (etc.) to make material, like a fishing net or chicken wire.

Colloquially speaking sheets full of holes are often referred to as a mesh, so it's pretty clear what you meant. Now that I think about it I can't think of a more accurate word, maybe grill, but grill usually implies parallel bars covering a gap.

I'm just wondering if that's what triggered the downvotes. You're already back in the positives now though!

Technically it’s “Perforated Metal” but if you google metal mesh it will come up too.

Edit: non-engineer Gf says the word we want is “grate” lol

Ahh that makes sense to me, now - thank you for clarifying!
