Hey Ed ;
A tiny bit off'audio but for nice dress-up, You can't beat an '87 Cents' Store, purchase a pair of Storage-Totes, the things look like stiffer version, of CANVAS shop bags, etc.
Point is, those 10 inch cubes (28 cm), with bottom panel omitted, make 'attractive' little covers...; THEN, You insert 'Ugly' from 1992, speaker, with, I don't know...Bat Shit stains, or something...but insert with that 'thinner' fabric bottom, as Your sound output grill.
In other words, looking good, cheap, and 'cubes' would be perched up on any file cabinet or whatever, (blaring Santana!)
I think was 2 .39 $ at that thrift store.
