Our summary
Product Strengths
- Extremely clear sound, making them better for mixing and mastering than many other monitors
- Sound like main monitors, offering a large sound footprint not typically found in near-field or mid-field monitors
- Wide bandwidth accuracy and dependability at any volume level
- Midrange performance is particularly notable for realistic, unhyped accuracy, especially on naturally recorded human voices
- Bass performance combines extended bandwidth with great dynamic, pitch, and temporal accuracy
Product Considerations
- Require a significant break-in period
- To get the most out of them, an interface that can connect via AES is needed, as the conversion when using analog is not as transparent
- Correct placement is crucial; at least four and a half feet of distance is needed between the listener and the monitor to be able to get all of the sound that it's trying to give
- SoundAlign software, while useful for EQ adjustments, may introduce unwanted digital artifacts to the sound
- Expensive, these monitors are at the higher end of this sector and share that space with some well-respected designs
Comparisons (according to reviewers)
- Vs ATC SCM25a: The reviewer finds an absence of 'not hearing the box' evident in the 6-2 compared to the ATCs
- Vs Neumann KH310s: The 6-2s outperform them in every respect, sounding much better, with other monitors sounding colored by comparison
- Vs ATC 150s: The reviewer prefers these PMC6-2s over the ATC 150s
Takeaway: The PMC6-2 is a high-performance studio monitor that delivers exceptional clarity and detail. For those seeking accurate and dependable sound at all volumes, these monitors are worth consideration.

Our take on the brand
The PMC6 is packed with innovation and providing the same sonic signature as our renowned larger monitors, it's ideal for smaller control rooms or for use in larger immersive systems, where its astounding resolution allows critical mix decisions to be made with absolute confidence.
With 20mm of excursion, the bespoke 6-inch bass driver is designed specifically to integrate with our latest ATL™ bass-loading and Laminair™ airflow technologies. The combination outperforms most 8-inch monitors, offering unparalleled bass extension, headroom, dynamics, and low distortion at all levels.
The high end is courtesy of a one-inch precision-built fabric soft-dome tweeter, with a shallow waveguide that creates wide, tonally consistent dispersion and rock-solid imaging. Both the bass and treble drivers are precisely and individually controlled by a pair of 200W ultra-low-distortion, high-damping-factor Class-D amplifiers.
Whether in portrait or landscape placement, the PMC6's sophisticated DSP engine automatically adjusts the crossover, ensuring optimum tonal accuracy, phase and imaging. The monitor can be calibrated using the rear-panel controls or with PMC's intuitive browser-accessible SoundAlign™ software.
The PMC6 can be upgraded by adding a PMC8 SUB to create a full-range, free-standing PMC6 XBD system. Activating the 'XBD' DSP mode ensures the perfect marriage of the two units, creating a clean LF extension down to 25Hz.

Our take on the brand
Our Summary
Product Strengths
- Delivers greater tightness and precision from the crossover point on down
- Delivers an extended high-frequency range, with greater detail and more openness without harshness
- Stereo imaging is amongst the best
- Has no sweet 'spot', which allows the engineer, producer, and client a fairly similar listening experience
- Has a smoothly extended bass response that reveals what is really going on in that elusive bottom octave
Product Considerations
- The BM-15As may be overkill for a smaller mixing environment and better suited for larger rooms
- High end is as clean and accurate as the BM-12s, but the mids were a little lacking
- While they have a slightly forward characteristic, it doesn't get in the way of accurate monitoring
Comparisons (according to reviewers)
- Vs Dynaudio BM-12 MK3s—BM-15A has more bass extension and pure raw SPL power
- Vs Dynaudio BM-12 MK3s—BM-12 MK3s have more detail in the mid-range
- Vs Dynaudio BM-12 MK3s—BM-15A are far louder and put out substantially larger amount of energy in the bass and subs
- Vs Genelec, Focal, Neumann, and Event—the Dynaudio BM series are in the same class as these monitors
Takeaway: The BM15A is a speaker that gives great stereo imaging with a wide frequency range, and produces an accurate sound which is nice to listen to for long periods. Full-range monitoring in a smaller studio is possible with these speakers.
