Short answer: the Arendal 1961 Monitor on measured sound quality, the Moondrop M4P MTM on price. The Arendal 1961 Monitor ranks #8 of 87 bookshelf speakers at $1150. The Moondrop M4P MTM ranks #12 at $920, $230 cheaper.
On the Arendal 1961 Monitor side: A physically robust build the reviewer calls “a little bit of a tank,” delivering low compression, low distortion. Set against that: Bass rolls off around 70-80Hz, so it cannot be used as full-range mains for music without a subwoofer.
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. Set against that: Vertical placement is very fussy: staying within about ±20° of the tweeter axis is essential.
Buy the Arendal 1961 Monitor if sound quality matters more than the price. Buy the Moondrop M4P MTM if the price matters more than sound quality.

The Two Speakers In Full
Arendal 1961 Monitor: $1150 per pair Arendalsound eBay
Pros: A physically robust build the reviewer calls “a little bit of a tank,” delivering low compression, low distortion, and overall really good neutrality - one of the reviewer’s top 10 picks under $1,500 across roughly 250 speakers tested. Works well both as home theater mains and as surrounds. Independent ASR Klippel measurements corroborate the low-distortion finding: THD at 86dB SPL/1m stays well below the reviewer’s audibility threshold, and even at 96dB SPL/1m it stays “far better than most bookshelves” thanks to the built-in high-pass filter that protects the woofers.
Cons: Bass rolls off around 70-80Hz, so it cannot be used as full-range mains for music without a subwoofer, and a sub is recommended for home theater use as well. Vertical radiation window is narrow, typical of MTM (mid-tweeter-mid) layouts - tighter than a standard two-way’s roughly ±20° - so a second home theater row sitting above or below the tweeter axis will hear a noticeably different tonal balance. ASR’s CEA2034 measurements show the response is elevated above 2kHz with resonant peaks around 3kHz and 9kHz, leading the reviewer to predict it will “likely sound bright.” Those same resonances show up as lingering ridges in the cumulative spectral decay (waterfall) at 96dB SPL/1m.

Moondrop M4P MTM: $920 per pair Shenzhenaudio eBay
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.
