Moondrop's first loudspeaker, and the measurement-first ethos of its in-ear monitors scaled to the desktop. The M4P-MTM is a passive two-way in a vertical MTM (D'Appolito) layout — a 1-inch aluminium-magnesium dome tweeter flanked by two 4-inch carbon-cone woofers — for flat, low-distortion near-field sound with controlled vertical dispersion. It needs an external amplifier and has dual binding posts for bi-wiring or an active crossover.
