The on-walls are another one of these big secrets. If prospects knew how good they sounded, they'd go for them over floor-standers. But they have less macho man factor and that's important for some.
I'd like to see active LFROW.
So true. I've now tried every M5HP variant, and OW are my favourite. They sound every bit as good as the bookshelves, and integrate so nicely with a big wall-mounted TV. Macho man factor can be achieved simply by removing the grilles.
If I had a dedicated music listening space that allowed for proper placement, I'd likely opt for traditional bookshelves/floorstanders.
