I doubt if internet radio will ever completely overtake broadcast radio. Royalties and greed will kill internet radio, and are doing so now.

i can see a fire happening if you want to deaden sound that much either build the heat-sink into walls of speaker or deaden it rigid foam though be sure to cut ventilation holes in it, i be wondering whether if there was a rfi issue or something because i wouldn't packing something with a circuit board in it like this, this looks like someone's build project using a mix of pillow stuffing  sound proofing foam as a sound masking agent and something to mask plausible  rfi issues.. i'd be concerned that that you or whoever built this is in risk in starting a fire because even this would be need adequate air flow to whatever interal electronics there is cool...

this honestly looks like a kit build and shouldn't be on sale to the general public..

if you want sound proof that's fine but be sure you aren't masking up any potential issues.. by adding things that should never appear in  an electric device with other circuitry being..

i would suggest people who have this in kit build form a someway a cnc machine so if you have to make somethig to suit this it can be done on this machine..

just looking at this photo is  a recipe for a fire..

Among its many tricks, the Raspberry Pi is capable of putting clock signals signal out on its GPIO pins, and that turns out to be just the thing for synthesizing RF signals in the amateur radio bands. What [Zoltan] realized, though, is that the resulting signals are pretty dirty, ...
