I think these are Missions of the kind you would have bought in Richer Sounds a few years ago.
Here’s hoping they don’t have ports at the back (or the bottom, or frankly firing anywhere except directly forward).
TBH it looks like this isn’t some kind of horrific accident, rather I think the shelving has been designed deliberately to accommodate the speakers in this way.
FWIW this one isn’t in London, but is in an area that I’m looking at.
