Nearfield passive speaker recommendations please (ATC SCM11 vs KEF LS50 meta)

Oranfoster I'm debating between the 7, 11 or 19. Its such a hard choice. I gotta get the speakers above 3 computer monitors and maybe tilted. One idea I had was flipping the speaker so the tweeter is on the bottom. But my dealer said he doesnt recommend that for the 19 as it will become too top heavy. But should be ok for 11 and def 7.

Its a tough choice. The fact you are using 19s well at your desk is encouraging though.

I just got kef ls50 meta, I am driving it with Cambridge cxa81. I was testing the speakers for the bass it was almost negligible compared to the ones B&W 606 I replaced.  Do I need to be worried and get it checked?

A standard 2 way should be fine for 4 feet away. Coaxials generally shine much more on a desk setting where you may be above or below the tweeter axis and closer than where a 2 way can achieve acoustical summation, so listening distance of say 1-2 feet.
