Short answer: the Moondrop M4P MTM for the higher ranking, the Zaph Audio ZA5.2 TM for the lower price. The Moondrop M4P MTM ranks #4 of 21 bookshelf speakers at $920. The Zaph Audio ZA5.2 TM ranks #6 at $383, $537 cheaper.
The case for the Moondrop M4P MTM: MTM (mid-tweeter-mid) two-way layout with dual 4” carbon-cone woofers flanking a 1” aluminum-magnesium dome tweeter, crossed over at 1.8kHz. The catch: Vertical placement is very fussy: staying within about ±20° of the tweeter axis is essential.
What the Zaph Audio ZA5.2 TM gets right: CEA2034 spinorama shows a fairly smooth on-axis response. The tradeoff: Predicted in-room response is tilted upward toward the treble, which the reviewer flagged as a likely audible brightness.
Buy the Moondrop M4P MTM if the ranking matters more than the price. Buy the Zaph Audio ZA5.2 TM if the price matters more than the ranking.

The Two Speakers In Full
Moondrop M4P MTM: $920 Shenzhenaudio
Pros: MTM (mid-tweeter-mid) two-way layout with dual 4” carbon-cone woofers flanking a 1” aluminum-magnesium dome tweeter, crossed over at 1.8kHz. Wide horizontal radiation of about ±60° through the midrange and still around ±50° near the tweeter, giving an expansive, enveloping soundstage on well-recorded stereo material. Noticeable mid-bass “thump” around 100-160Hz that adds a sense of punch and kick-drum impact, more pronounced than the reviewer’s Audiofirst Fidelia reference. Rolled-off, laid-back treble (roughly 1-2dB below linear) rather than the 2-5dB high-frequency boost common on speakers marketed as “detailed” - a plus for listeners who find brighter speakers fatiguing. Tonal balance stays consistent whether pointed straight on or toed out about 30°, so side-to-side seating position doesn’t change the sound much. At $920/pair in a compact monitor cabinet (13-14 lbs), reasonably priced for the format.
Cons: Vertical placement is very fussy: staying within about ±20° of the tweeter axis is essential, because the two woofers cancel each other through the crossover region (classic MTM lobing) - sit above or below that window and the upper midrange loses clarity and detail. SPL-limited: noticeable compression showed up both subjectively (thinner-sounding transients at 80-85dB/10 feet) and in measurements, with roughly 1.5dB of dynamic-range loss and about 3dB of added distortion under instantaneous compression testing. Harmonic distortion jumps substantially at 96dB versus 86dB (mostly second-order, so less audible than it looks on paper), and multitone distortion rides right at the reviewer’s 3% threshold at full output. Low impedance (3.7-ohm minimum, 1.7-ohm minimum EPDR) means a Class AB amp may run hot over longer sessions; a Class D amp is recommended for better thermal headroom. Designed primarily for nearfield use (about 1 meter); farfield listening is more of a gamble since dynamic range drops off noticeably at distance. Slight sibilance and a mild upper-midrange dip give a touch of a recessed, warm character alongside the bass emphasis. Bass reaches only about 50-60Hz in-room, and not with much volume before running into the SPL limits noted above.

Zaph Audio ZA5.2 TM: $383 Madisoundspeakerstore
Pros: CEA2034 spinorama shows a fairly smooth on-axis response. Cumulative spectral decay (waterfall) is clean overall, with only minor lingering energy around 400-700Hz.
Cons: Predicted in-room response is tilted upward toward the treble, which the reviewer flagged as a likely audible brightness. Low sensitivity of about 82dB requires more amplifier gain than typical. Relative harmonic distortion is excessive in the low frequencies, climbing to 6-8% under a 10-volt test signal in the 60-150Hz region - notably worse than typical two-way designs in this price range. Impedance runs close to 7 ohms through much of the audible range, with additional peaks that make it a moderately demanding load for a low-sensitivity design. Vertical directivity narrows unevenly above about 1kHz, typical of this MTM-adjacent tweeter/woofer spacing.
