Steel plate speaker cabinets would they work

[56oval]

I'm need to build cabinets for a project I have .
Been reading different threads on this forum about MDF & Ply .
Also looked at 13mm ply carbon fibre another layer of 13mm ply then a final 3 layers of carbon fibre .I have heard a cabinet constructed this way with the same drivers I'm using .
I do a bit of work with steel and looking at my mate engineering shop I'm beginning to see drivers in RHS & Large tube steel .
Could this work .
Bass driver needs to be in a 60litre cab ,mids in a sealed 12 litre
and the tweeter sitting on top no cabinet .
Or should I just build it and suck it and see .

Cheers

Would they work? Yes.

Would they be an improvement over traditional materials like MDF and plywood? No.

The functionality required of a speaker cabinet is easily met by much more user friendly materials like wood products.

I'm not saying they wouldn't be bada$$, and if you have the means don't let a little thing like practicality keep you from your vision.

Whether it is worth it or not is entirely decided by you.

If you were inclined to do a steel frontplate, one potential advantage is that a very thin panel could be incredibly strong, so you wouldn't have to worry about chamfering driver mounting holes to allow free airflow.

A combination of Steel and Aluminum with something sticky and gooey in between the layers is excellent for speaker cabinets.

If you want to just use Steel, then lining the inside with "roof repair" tape will help deaden the walls.
