I couldn't find where Paradigm or Martin Logan (same parent company as Anthem, BTW) have any true on-wall speakers. The only ones KEF has at the moment are the KEF T-series, including T201 and T301 variants.
As much as I like KEF, the best true on-wall speakers I've ever heard are the Totem Acoustics Tribe series.
