1. Introduction
On October 17th, 2025, during the 7th Chengdu International Audio & Visual Show, Moondrop officially released two new speakers: the Moondrop M4A-MTM and the Moondrop MM3A. The former is positioned as a compact active monitor with professional features, while the latter is presented as a versatile desktop speaker designed for multi-purpose entertainment.
2. Moondrop M4A-MTM: 4-inch Active Monitor with Auto-Calibration
The Moondrop M4A-MTM is presented as a solution for professionals, prosumers, and audiophiles operating in space-constrained environments. It is a near-field active monitor featuring an MTM (Midwoofer-Tweeter-Midwoofer) driver configuration, which consists of dual woven-composite woofers and an aluminum-magnesium alloy dome tweeter.
The system is specified to deliver a maximum power output of 100W (at THD ≤ 1%), with a bass extension down to 40 Hz (-3 dB) and a maximum SPL of 100 dB. Signal processing is handled by a 32-bit standalone DSP chip that utilizes Finite Impulse Response (FIR) filters to achieve a linear phase response. Connectivity is comprehensive, offering balanced XLR, unbalanced RCA, and both Toslink optical input and output. The enclosure is engineered with a low-diffraction cabinet profile and incorporates a rear-firing bass reflex port.
A significant feature is the inclusion of a calibration microphone with the purchase. The calibration microphone works with an automatic room correction system developed by Moondrop, that operates independently of any host operating system. This integrated calibration system has three switchable modes: a "HiFi" mode, a "Monitor" (flat) mode, and the user-calibrated mode.
To provide some context, the M4A-MTM is specially designed for professional users with limited room space (e.g. mixing engineers and entrepreneurs renting small apartments to kickstart their careers), as well as audio enthusiasts constrained by spatial limitations (e.g. college students who may not yet afford their own homes but dream of owning Hi-Fi speakers). In China, housing prices are quite high, and the average living space per person is significantly smaller compared to the United States. Many young people there rent apartments and don't have enough room for tower speakers. Even when space is available, irregular room layouts and poor acoustic treatment often pose challenges. Consequently, near-field monitors placed on computer desks present an ideal solution. The M4A-MTM is intentionally designed with a slim, tall profile to occupy minimal desk space, avoiding competition with computer monitor for precious desk surface area. Its engineered height ensures the tweeter aligns precisely with the ears of a seated listener.
The included measurement microphone not only facilitates convenient calibration for professional users (note that competitors such as Neumann require separate purchases for such accessories) but also helps non-technical enthusiasts gain knowledge in speaker calibration and room acoustics — after all, not every buyer has the patience to thoroughly study works like Sound Reproduction.
3. Moondrop MM3A: 3-inch Active Multi-purpose Desktop Speaker
The Moondrop MM3A is positioned toward the general entertainment user seeking a substantial performance upgrade over standard computer speakers for applications such as PC gaming, media consumption, and music listening.
This model is a two-way active design, employing an aluminum cone woofer and a silk dome tweeter. Low-frequency reinforcement is achieved through horizontally-opposed dual passive radiators, an engineering choice intended to extend bass response from a compact, sealed enclosure without the placement constraints associated with ported designs. It is rated for 40W of maximum power output per channel (at THD ≤ 1%), with a claimed bass extension of 50 Hz (-3 dB) and distortion under 0.5% at typical listening levels.
The speaker utilizes a full-DSP digital crossover with 4th-order (24 dB/octave) slopes. Its connectivity options are extensive, including Bluetooth 5.0 with LHDC codec support, USB, 3.5mm AUX, and optical inputs. A notable feature for compatibility with gaming consoles is a switchable UAC 1.0 / 2.0 mode for the USB connection.
The enclosure itself features a low-diffraction profile and a built-in 10-degree upward tilt to optimize the listening axis for a seated desktop user. Furthermore, the system allows for user adjustments via a Parametric Equalizer accessible through a free mobile app and a free PC software.
The design philosophy of the MM3A targets mass-market entertainment users seeking basic audio functionality, such as young PC gamers and home theater enthusiasts who use computers for movie viewing. It incorporates passive radiators to enhance low-frequency performance and supports multiple input methods such as Bluetooth. The driver orientation is intentionally angled slightly upward, allowing the speaker to direct sound toward the listener's ears without requiring precise positioning when placed on a desktop.
After an on-site audition of these speakers, I found their acoustic signature exceptionally neutral and balanced, with a flat frequency response and only a slight deficiency in low-frequency extension. In a private discussion with a Moondrop development engineer, I learned that the M4A-MTM is benchmarked against industry reference-grade competitors such as the Neumann KH80 DSP, rather than only domestic rivals like Topping—underscoring Moondrop's substantial market ambitions. Additionally, a complementary subwoofer is in development and is expected to launch as early as next year, addressing the M4A-MTM's low-frequency shortcomings.
Pricing for both the M4A-MTM and MM3A remains undisclosed; we will have to wait for the official release for confirmation. Nevertheless, the pricing is expected to be accessible. I am pleased to see increasingly capable and cost-effective products emerging in the professional monitor segment. Historically, professional reference monitors have commanded premium prices, but as more science-driven Chinese manufacturers introduce affordable, high-quality studio monitors, professionals have more options and mainstream consumers can access acoustically balanced systems with linear tuning characteristics.
