Our take on the brand
As with any PMC loudspeaker, thanks to its super-consistent dispersion and tonal balance, the PMC8-2 may be simply and seamlessly combined with smaller PMC speakers to create larger multi-channel or immersive systems. The twin bass drivers are partnered with the same PMC55 mid-range tweeter, DSP system and four channels of 400W Class-D amplification used in the PMC6-2. Again, the speaker is configurable directly via the rear panel or using the browser-based SoundAlign™ software from a computer or tablet.
Together with the precisely tuned ATL™ cabinet and hexagonal Laminair™ vents, the PMC8-2 delivers phenomenal performance that approaches that of our Main reference monitors, with smooth and consistent bass response down to 25Hz, a revealing mid-range and wide, stable sound-staging. As with the rest of the range, the PMC8-2's superb definition, fidelity, dynamics and bass accuracy allow mix decisions to be made quickly with complete confidence, and with no listening fatigue even after long sessions.
PMC8-2s can be upgraded through the addition of a PMC8-2 SUB to create an XBD system, enhancing the system's bass headroom by 6dB. Dedicated short and taller floor-stands are available for the PMC8-2 and PMC8-2 XBD systems which position them on the ideal listening axis.

- The size and weight of the A25Ms mean they probably will not be considered for nearfield duties by the majority of potential users
- The overall tonal balance is a little prominent in the upper-mid band, and this sometimes adds a slight edge to some mix elements
- If considering a move to mid-field monitoring, room acoustics should probably be considered at the same time
- Enclosure color is an acquired taste
Comparisons (according to reviewers)
- Vs ATC SCM45s, the ATCs just had that extra tiny level of detail in the mids—it comes down to personal choice
Takeaway: The A25M is genuinely revealing monitors that can provide great insight into the components of a mix and how they fit together. These are spectacular monitors with a tight, controlled low end and super precise stereo imaging, making them an excellent mid-field monitor for mixing and mastering.
