Short answer: the GR-Research NX-Treme for open-baffle soundstaging, the KEF Blade Two Meta for a point-source coaxial design. The NX-Treme’s open baffle radiates in all directions for a huge soundstage, but it is very tall and needs a GR-Research open baffle subwoofer on each side. The Blade Two Meta surrounds a coincident mid/tweeter with four 6.5-inch mid-bass drivers, though it shows a 2dB dip and slight resonance around 200Hz.
Buy the GR-Research NX-Treme. Both are rated the same for sound quality, and it costs $18,338 less than the KEF Blade Two Meta.
