Short answer: the GR-Research NX-Treme, unless you want deep bass without subwoofers. The MoFi SourcePoint V10 Master Edition reaches about 30 Hz in-room on its own, but its ~89 dB sensitivity asks for more amplifier power. The NX-Treme is #1 of 71 and images in every direction, though it is very tall and needs a GR-Research open baffle sub on each side.
On the GR-Research NX-Treme side: Amazing in terms of soundstage and imaging as the speaker can radiate in all directions and not have internal reflections due to there not. The tradeoff: Very tall and will require GR-Research open baffle subwoofers one on each side.
The case for the MoFi SourcePoint V10 Master Edition: Extended bass to approximately 30 Hz in-room without subwoofer. Set against that: Moderate sensitivity (~89 dB) means amplifier power requirements higher than many alternatives.
Buy the MoFi SourcePoint V10 Master Edition. Both are rated the same for sound quality, and it costs $1667 less than the GR-Research NX-Treme.

GR-Research NX-Treme: $9662 per pair for the kit with subs (assembly required) Gr-research eBay
Pros: Amazing in terms of soundstage and imaging as the speaker can radiate in all directions and not have internal reflections due to there not being a speaker box. One of the highest sensitivity speakers around. Open baffle mids, highs and bass (using GR-Research Open baffle subs). If you have not heard open baffle bass, you must hear it in person, there’s no going back. Amazing in terms of imaging as the speaker can radiate in all directions and not have internal reflections due to there not being a speaker box. Can easily be driven by tube amps due to the mild impedance. Measured bass extension of <20Hz (-3dB).
Cons: Very tall and will require GR-Research open baffle subwoofers one on each side

MoFi SourcePoint V10 Master Edition: $7995 per pair Crutchfield eBay
Pros: Extended bass to approximately 30 Hz in-room without subwoofer; images with excellent precision indicating tight frequency response matching between speakers. Integrated bass management with three-way treble attenuation switches for room tuning. New design from Andrew Jones represents reviewer personal second choice (behind only KEF Blade 2 Meta at 29k) among hundreds of systems auditioned; ranks above Dutch & Dutch 8C, JBL 4367, and JBL M2. Measured bass extension of 38Hz (-3dB), with a measured sensitivity of 88.8dB.
Cons: Moderate sensitivity (~89 dB) means amplifier power requirements higher than many alternatives. Deep bass extension ends above subsonic frequencies (pipe organ territory below 17 Hz requires subwoofer).
