PMC MB2 SE review

Studio monitoring speakers sit at the very core of PMC’s DNA. The letters PMC are an initialism for Professional Monitoring Company, after all. The brand’s earliest products were aimed at the pro world, with the original MB1 monitor being introduced in 1993, just a couple of years after the company was founded.

More than three decades on, the current PMC MB2 SE mirrors that early monitor’s formula right down to its brutal appearance, formidable cabinet size and drive unit array. Of course, PMC hasn’t been idle over those decades, with the current design featuring improved ingredients across the board that take in everything the brand has learnt over the years.

Design & build

Technically, the PMC MB2 SE is a standmount design, but at 87cm tall it is not that much shorter than many of the floorstanders that pass through our test room. Make no mistake, this is a huge speaker, measuring 38cm wide and over half a metre deep.

A single MB2 SE is as visually obtrusive as a washing machine, and you need two of them for stereo, of course. Those with modestly-sized listening rooms need not apply.

The MB2 SE is a three-way design. It combines a 27mm Sonolex soft-dome tweeter, a 75mm doped-linen dome midrange, and a rather distinctive 31cm Radial doped-paper bass driver, with crossover points set at 3.8kHz and 380Hz. Connection is made via three sets of chunky binding posts.

Those spokes in front of the bass cone aren’t just there to look impressive. They serve to dissipate heat generated in the motor system when working at high volume levels with bass-heavy source material.

We suspect such considerations are unnecessary for normal domestic use. But it is nice to know the speakers can cope if you go nuts with the volume level during a spirited listening session.

The use of transmission-line bass loading has been baked into PMC’s products from the beginning, so it is no surprise to see the technique used here. The company has long promoted this configuration to be the most effective way to achieve clean, low-distortion bass output from a box speaker.

The rear-firing output from the MB2 SE’s bass unit travels down a folded, carefully damped path inside the cabinet. As this signal passes through, most of the sound gets absorbed, leaving only the lowest frequencies to emerge from the substantial vent at the top of the front baffle.

Importantly, this low-frequency sound is in phase with the bass unit’s forward output, and if properly tuned, fills in below the point where the woofer starts to tail off. The transmission line inside the MB2 SE has an effective length of 3m.

A further advantage of such a design is that it adds internal bracing inside the enclosure, making the structure impressively rigid. The MB2 SE is beautifully made and finished to a high standard, just as its hefty price tag demands.

It is available in four lovely real wood finishes: the Grand Walnut of our review samples, Amarone, Natural Oak and Jet Black. But rather like a gorilla dressed in a tuxedo, none of these come close to hiding the design’s studio heritage. We can’t imagine anyone calling it a stylish design, but we still warm to the MB2 SE’s brutal yet entirely functional appearance.

Any speaker at this level positively demands top-class partnering equipment. Our sources are Naim’s ND 555/555 PS DR music streamer and Technics SL-1000R/Kiseki Purpleheart MC record player feeding a Burmester 088/911 Mk III pre/power amplifier.

We also try PMC’s Cor integrated amplifier to see how the speakers cope with more modest but still capable amplification. Our speaker benchmarks are ATC’s SCM50 speakers and a pair of Marten Audio Parker Duo Diamond standmounts.

It will come as no surprise to find that such a big speaker shines brightest when given plenty of space to breathe. Our main test room is 3 x 7 x 5m (hwd) in size, which is reasonable by general standards but probably at the lower end of acceptability for these monitors.

We end up with them around a metre into the room, and slightly angled in so that the tweeter axis crosses a little behind us when we are seated in the main listening position.

Sound

Set up in this way, these PMC speakers deliver an expansive soundstage with instruments and environmental acoustic clues nicely focused. There is a pleasing resolution of depth information and an impressive degree of image stability when the music gains in complexity, or the volume level rises.

It is fair to say that the soundstage doesn’t quite float free of those substantial cabinets in the manner that smaller alternatives such as the Marten speakers manage, but it is still good enough to avoid complaint.

Given their size, it is fair to expect that these PMC speakers can go loud and deliver deep bass, and they do. We play an old favourite, Setting Sun by the Chemical Brothers, and the MB2 SE have a ball. They play loud, way louder than we would ever need, yet remain wonderfully refined and composed when doing so. They don’t harden up or become edgy when pushed.

It all adds up to a lovely sense of ease, where the listener can relax knowing that the speakers can cope with whatever is thrown at them.

Then there is the bass. The MB2 SE are a great advert for transmission lines. If engineered poorly, such designs can sound uneven and ponderous, but PMC’s experience has delivered a performance that ticks all the boxes as far as low-end performance is concerned.

As we run through our array of bass-torture tracks from Hans Zimmer’s soundtracks for Interstellar, The Dark Knight and Inception to Massive Attack’s Mezzanine and Soul II Soul’s Club Classics Vol.1, we can’t help but sit back in awe at what these speakers can do.

They dig impressively deep, yet combine that with a blend of power, finesse and tunefulness that is rare. There is a degree of authority on offer that is a match for anything we have had in our test rooms.

The speakers’ excellent bass gives a firm foundation for the rest of the frequency range. Voices come through with impressive clarity and definition. These PMC speakers are as insightful as they come through the midrange, but unlike many such high-resolution designs, they don’t filter out the natural warmth and body of voices. As we listen to Sade’s Diamond Life, we can’t help but admire the speakers’ skill in resolving vocal textures and the dynamic nuances that communicate emotion.

Orchestral crescendos and other larger-scale dynamic shifts are handled with equal finesse. Once again, we note the speakers’ composure and the apparent ease with which they go from loud to quiet and back again.

As a bonus, we are happy to note that the MB2 SE sound good at quiet volumes too, with the bass staying present and balanced with the rest of the frequency range to a surprising degree. If you are looking for ideal late-night speakers, consider these.

Verdict

The PMC MB2 SE are surprisingly capable all-rounders. Their size and driver array correctly foreshadow their sonic muscularity, whether we are talking about loudness capability or bass extension.

However, we weren’t expecting them to be so refined and insightful. Sure, they are hugely transparent and will uncover shortcomings in both the partnering electronics and source material with ease. However, they never forget to put the music first.

If you have the space and system to do them justice, these are speakers you really have to hear. We are utterly charmed by them.
