What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

Product Strengths

  • Neutral sound signature is suitable for critical listening and reveals details in recordings
  • Transmission line design allows surprisingly deep and well-defined bass for its compact size
  • Clarity, resolution, and the ability to separate instruments are noted
  • Wide and airy soundstage creates a sense of space and immersion
  • High frequencies are described as refined, open, and airy, with good extension and controlled sibilance

Product Considerations

  • Revealing nature means it can expose flaws in recordings and upstream equipment
  • Soundstage depth was an area one reviewer struggled with
  • Speaker is neutral to cool-ish, not a full, rich sounding speaker
  • Revealing nature also makes placement sensitive

Comparisons (according to reviewers)

  • Versus the GoldenEar BRX, the PMC twenty5.21i was cooler in balance, but faster
  • Compared to the Harbeth P3 ESR, the Harbeth has heart, body, and soul, making one feel like there are human beings making music
  • The PMC twenty5.21i bass is faster and clearer than ProAc, which seems slower and lumpier in comparison

Takeaway: The PMC Active twenty5.21i is a compact speaker that delivers a detailed and neutral sound with impressive bass for its size. It's a great choice for those who want accurate sound reproduction and appreciate hearing all the nuances in their music.

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

The Active twenty5.21i is the smallest in the range, but its impact and portrayal of any piece of music is far from small, thanks to PMC's ATL bass loading and 2x100W active amplification.

Small but mighty – that's the Active twenty5.21i: it may be the most compact model in the new Active twenty5i range, but it benefits from the same cutting-edge active amplification as the other models in the line-up, combining an active crossover with 100W of power for each driver. It also benefits from PMC's Advanced Transmission Line technology, delivering bass impact you'd expect from a much larger design.

It is ideal for small-to-medium listening environments where you still want detailed bass, ultra-realistic mids and delicate highs with maximum musicality. It's equally happy to be mounted on a stand or a bookshelf and is an excellent choice for effects speakers in an immersive sound system.

The Active twenty5i series is an elegantly simple solution for any music lover: add a preamplifier or streamer with a volume control for a complete music system.

PMC8-2

Reviews

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.

"Active 3-way nearfield reference monitor with ATL™ bass loading Frequency response: 25Hz - 25kHz (- 3dB @1m full space, on-axis) Max. cont. SPL: 113dB @1m (half space value calculated as +3dB from full space measurement. Unweighted input, 20-20kHz Pink Noise (IEC) with 12dB CF for 2 hours AES2-1984 duration) State-of-the-art Class-D amplifiers: HF 400W, MF 400W, LF 2x 400W Analogue / AES3 digital input (16/24-bit, 18 -192kHz sample rate) Digital 'through' output (AES3 24-bit 96kHz SoundAlign™ network control interface for single or group EQ & settings Sophisticated DSP crossover, driver protection, EQ, and delay/polarity options PMC8-2 + PMC8-2 SUB creates PMC8-2 XBD, with up to 6dB of additional headroom Optional dedicated floor stands for PMC8-2 (40") and PMC8-2 XBD (19")"

Product Strengths

  • Unparalleled clarity, definition, and utmost accuracy
  • Excellent bass extension and clarity, as well as proper tonal balance at every volume
  • Super wide dispersion, and thus a bigger sweet spot

Product Considerations

  • It would be overkill in smaller rooms
  • A pair is a significant investment, so it makes sense that it's geared toward large, professional recording environments
  • They weigh nearly 100 pounds apiece

Takeaway: The PMC 8-2 is a wise investment for professional studios that delivers detailed and accurate monitoring, so it could very well be the only monitor needed It uses proprietary technology to deliver its signature sound

Expand Details

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.

Released
2022
Focus 10 is more than just a pair of active loudspeakers. It's a complete music system, packed from top to bottom with the technology that's taken Dynaudio to legendary status – allied with the most cutting-edge wireless features we could think of. And we thought of a lot.
Check Amazon
Dynaudio is a hifi speaker brand known for its unique external voice-coil construction, which allows for larger voice coils that improve thermal power handling and reduce thermal compression. The brand has a heritage in professional sound production and uses advanced materials like the Esotar 40 tweeter and rare 240mm drivers to deliver superior dynamic realism and headroom.
Expand Details

Our Summary

Product Strengths

  • Integrated technology allows direct high-resolution listening without extra devices
  • The speaker uses the same Pascal Class D amplification and processing technology from Dynaudio's Pro line Core series
  • Discrete amplification channel per driver: 110 watts for the tweeter and 280 watts for the woofer
  • Dirac Live room correction is available, which can tune some of the annoying sounds of a garage, for example, using the soft dome tweeter

Product Considerations

  • Running a digital coaxial cable from one speaker to the next results in the signal being sent at 24-96 kilohertz, which is a lower quality than what the master speaker receives (24-192)
  • There is no HDMI arc or e-arc connection
  • Drilling holes may be required to attach the speaker to stands
  • Setting up the speaker with the app is not as quick or seamless as Bluesound
  • A microphone is required to do Dirac room calibration

Comparisons (according to reviewers)

  • Vs PSB Alpha IQs: Plays louder with a higher level of amplification
  • Vs Dynaudio Core 7: The Core 7 has more power and a slightly better tweeter and woofer, but is not as aesthetically pleasing and needs a Bluesound Node
  • Vs Dynaudio Evoke: It is similar to an Evoke speaker, but with a bigger woofer

Takeaway: The Focus recMsY5ljWopDD7UU is a sophisticated wireless speaker that pulls technology from Dynaudio's Pro line and features Dirac room calibration. It is ideal for someone looking for high-resolution listening without extra devices and who values sophisticated sound and aesthetics.
