Short answer: the Moondrop M4P MTM for a dedicated listening position, the KEF LS50 Meta for a more forgiving layout. The M4P MTM is an MTM two-way with dual 4-inch carbon-cone woofers flanking a 1-inch aluminum-magnesium dome tweeter crossed at 1.8kHz, but vertical placement is fussy: stay within about +/-20 degrees of the tweeter axis. The LS50 Meta’s Uni-Q adds F3 of 67Hz and F10 of 42Hz.
Buy the KEF LS50 Meta. It is rated higher for sound quality, and the $279 you would save on the Moondrop M4P MTM does not close the gap.
