Best Placement for Nearfield Dual Concentric Speakers?

I am using a pair of KEF IQ3s (coaxial drivers) for nearfield usage. What is the best way to orient them in a nearfield setup? I know this isnt really intended for Nearfield use, but it should be better than a tradition bookshelf since its a single point source.

I heard that these sound better on the off-axis? Does the equilateral triangle rule still apply?

Thanks
