Better to use 'waste felt' with a internal or external ( it doesn't matter) net

A hanging pioece of fiberglass wall insultation hung from the top and fixed at the bottom is sufficietly ridged.

Reminds me of a case around 1980 where a large onken bass reflex (large cabinet, 15" driver, large slit type openings next to driver) was used (festival du son, Paris) and to dampen the enclosure standing waves thick felt sheets were hung in the enclosure. It worked to a certain extend. (Jean Hiraga, l' audiophile)
Wrt to cld with felt, in those days to dampen resonances in tube of pick-up arm of record player, a lightweight solution was to apply a thin layer of felt covered by a thin adhesive tape layer. Worked extremely well, but visually not very attractive.
Look at car damping solutions, quite often a felt - bitumen like material is combined into a sheet or blanket and depending where used also a layer of plastic or thin aluminium applied to increase the damping result.
So in short it will do something, but if it is satisfying i am not sure.
The proposals for baffles suggested two things:
Some of these sound a lot like a furnace filter
(though I still think Roxul Comfortboard is a more likely material
Perhaps for experimentation, the interior of the enclosure could be slotted to accept baffles in various positions. With a removable side, you could easily try lots of different materials and schemes.
