I've found a good source of a down and dirty quick speaker box for vintage 10" and larger speakers when used with communications receivers.

A large cardboard box.

Looks ugly, cannot support much weight on its top and may not be optimum, but for communications receivers the speaker box is just fine.

And if you want to get really fancy, fill the box with leftover fiberglass insulation.
They do sound amazingly good.

Yes hadn't thought about insulation or anything else to fill the box.

I assume a little insulation attached to the inside box walls wouldn't hurt when using the box as an open back speaker box.

I'd close the box if I used insulation. Nasty to breathe & get into your paws too. :)
For fun, take a speaker and mount it inside a piece of SonoTube(tm) tghey use for concrete pillar forms. You can really tweek the length of the tube for just the bass sound you want. They can sound really good if cut to length correctly.

Very cool. Hadn't thought of that one either.

Closing the box definitely good for speakers that work best in a sealed box. For an open back box something else such as thin foam could be used if anything is actually needed.

I used to have some cardboard box speakers at the dealership, with used 6x9 car speakers and a used Chrysler radio mounted in a cabinet to run them. The boxes were weatherproofed with duct tape! (Our shop was basically a roof with three sides, no door) Too ugly to steal, they worked great for years!

Also you could inexpensively get fancy by testing various lengths of cardboard tubimg to make a tuned port!
