WHAT
DRIVES US
At PMC, we believe that music is what really matters; it’s what moves us and gives us the passion for what we do.
It’s relatively easy to create loudspeakers that colour or
atter music — but that has never been our way. The quest
for sonic neutrality and transparency has always been PMC’s obsession, using advanced engineering to reproduce music as vividly and faithfully as possible. Our designs are involved in every stage of music-making, from the recording studio to listening at home. From this experience, we know exactly how to present music as transparently as possible, just as the artist intended.
As we like to say, loudspeakers are where science meets art —
we take care of the science so you can connect with the art.

iMPROVING
A LEGEND
PMC’s now-legendary twenty5 series won ve-star ratings and awards worldwide, and were chosen to form the reference
surround system for What HiFi magazine — the speakers by
which all others are judged. But true innovators are never
satised. Our team never stops looking for ways to hone their
designs, using new technologies, materials, or discoveries,
including innovations from outside the audio industry. This quest
has led to the creation of the new twenty5i series speakers — where ‘i’ stands for improved. The new range offers everything that made the twenty5 series so sought-after, but with even greater realism, transparency and musicality.
INTRODUCING TWENTY5
The twenty5i range consists of four two-way loudspeakers
ranging from the compact shelf-mounting twenty5i.21 to
the oorstanding twenty5i.24, plus the agship three-way twenty5i.26. There’s also a Centre channel model and the
proven subwoofer for use in surround systems.
Our core belief is that the same ultra-high resolution loudspeaker, if properly designed, can be used throughout the
entire recording chain. That’s why our designs are employed at every stage of music-making, from lm soundtrack composers’
music rooms to recording studios through to the home, preserving the essence of the original performance exactly as the artist intended. Because the characteristics and tonality of all our speakers, from large to small, are essentially the same, it’s a simple matter to mix and match different models to create your perfect immersive audio system.
WHY THE
Toby Ridley is a key member of the research and
development team for the twenty5i range.
Toby, the twenty5 series was such a success — why
change it?
Since the twenty5 series was launched, we’ve carried
out a lot of research into improving high-frequency denition in loudspeakers and also into identifying and
reducing unwanted vibration, which can colour the sound you hear, making it less realistic and also causing blurred imaging. All of this research helped us hone the design of our agship, fenestria, and also fed into the design of the twenty5i range.
OK, so what’s different?
We’ve made changes to further widen the twenty5 series speakers’ already impressive sweet spot, and
reduce colouration from unwanted vibration. The oorstanders are mounted on new anti-vibration plinth
bars; they acoustically isolate the speakers from the
oor, dramatically reducing vibration transmission and
preventing unwanted vibrations being retransmitted by
the oor and passed back into the loudspeaker. The result is a more vivid, dened and open soundstage, free from smearing with high-frequency focus.
Apart from the drivers, what else is different?
We’ve also modied the crossover on all models in the twenty5i range. That’s the part of a loudspeaker that divides the audio input, so the high frequencies are only
routed to the tweeter, for example. We’ve lowered the point where audio crosses over from being handled by
the tweeter to the bass driver. That means the woofer isn’t being pushed to produce frequencies that are too
high for it, making the combined output of the drivers wider and more enveloping.
If you had to summarise the effect of all these changes,
what would you say?
The twenty5i series has an even wider sweet spot with cleaner, more three-dimensional imaging. The rst thing
that you’ll notice is that vocals are more natural and
tangible — it really does feel like a live performance.
Have there been any changes to the twenty5 drivers?
They were already pretty ne…!
We’ve incorporated a new tweeter, which was developed from the one in the high-end fact range.
The new driver is effectively two drivers in one — you can read more detail about its unique design later in this brochure. It also has a smoother frequency response
in the upper registers. Finally, the new driver has a
gently curved high-frequency dispersion plate and
grille; the plate is made from an extremely rigid glass-
bre composite that further widens the sound eld and
creates a stable platform for the driver to excel.
The twenty5i series has an even wider,
more consistent sweet spot, and
imaging is cleaner, sharper, more vivid
and more three-dimensional.
twenty5.21i in Diamond black
Although the twenty5.21i is the most compact model in the new range, there’s nothing small about the sound, which has the impact you’d expect from a much larger cabinet,
thanks to PMC’s Advanced Transmission Line technology. The speaker is ideal for use in small-to-medium listening
environments where space is at a premium, but where you still want detailed bass, ultra-realistic mids and delicate
highs with maximum musicality. Equally happy mounted
on a stand or a bookshelf, the twenty5.21i offers maximum
exibility for placement, and also makes an excellent
choice for effects speakers in an immersive sound system.

The more substantial twenty5.22i is designed for use in
larger spaces than the 21, and is equally at home on
its dedicated stands, console furniture or other at
surfaces. Its still-trim dimensions belie the lengthy ATL
concealed inside, which, coupled with the powerful
6.5-inch g-weave bass driver and Laminair
to deliver a clean, uncluttered and powerful low-end,

twenty5.22i in Oak
The 23 has proved to be the most popular model in our twenty and twenty5 range of speakers, and the twenty5.23i
looks set to follow their success. Its discreet and elegant
oor-standing form is perfect for lling medium-sized
rooms with transparent, authentic dynamics and effortlessly extended bass, and it will blend unobtrusively into any room, whether your chosen décor is modern or traditional. As with all of the twenty5i range, it will make the best of even affordable source electronics, and,
coupled with high-end amplication, will truly excel.

Choosing the right twenty5i model for your room size
PMC is respected worldwide for its soft-dome mid­range drivers, and the agship twenty5.26i, the largest in the range, features a third driver dedicated to the all-
important mid frequencies, where the critical detail is to be found in vocal recordings. The three-way design ensures that each important frequency range has its own dedicated driver, so that the speaker can ll even
the largest spaces with absolute transparency and
clarity. This is a sublime speaker that can expand with
you as you upgrade your system, and bring out the very
best in whatever equipment you connect it to.

twenty5.26i in Walnut
The twenty5.Ci is the latest iteration of PMC’s full-range centre loudspeaker for surround listening systems. It features twin g-weave bass drivers, and the new twenty5i treble driver in a package designed to provide the rock­solid centrepiece of an all-enveloping soundstage with the last word in ultra-realistic imaging. Delivering PMC’s trademark dynamic range, delicate highs and clean, powerful bass, this speaker’s wide, even dispersion allows it to be positioned high or low without affecting the clarity and dramatic impact of movie dialogue, allowing you to realise the full potential of an immersive audio movie playback system without compromising intelligibility.

twenty5.sub in Diamond black
The twenty5.sub remains the optimum partner for a twenty5i series immersive audio system, combining
active electronics from PMC’s renowned professional
systems, 400W Class-D amplication with ultra-low
distortion, PMC’s proprietary ATL
and Laminair
technologies, and a pair of the powerful 6.5-inch high­excursion bass drivers used on the twenty5i series. This sub can faithfully reproduce frequencies down to 22Hz, and
handle dynamic contrasts from the sonic complexity of a Hollywood blockbuster soundtrack to the precision detail of an orchestral performance, with maximum resolution and precision-timed bass.
Using its built-in rear-panel EQ, the sub can be nely
tuned to its listening environment, and also perfectly integrated with any accompanying surround or stereo speakers. Together with the compact twenty5.21i or 22 speakers, the sub forms a powerful system; the twenty5.
sub looks after the low frequencies, leaving the left and right speakers to reproduce the mid-range. The result is
performance close to that of the three-way twenty5.26i, but in a more compact, unobtrusive format.

• Turbulence is eliminated, increasing the efciency
of the ATL
• Removes air noise – only the music remains
• Higher maximum output and bass with supreme timing and dynamics
The twenty5i series takes audio performance to the next level by integrating Laminair vents into their designs. PMC’s Head of Design,
Oliver Thomas applied aerodynamic principles he discovered in
his previous employment in Formula One to ATL
, creating an
even smoother, laminar airow at the exit from the transmission
line. ATL
designs involve air moving at high speeds and under
pressure, and Oliver showed that reducing turbulence and
drag at the ATL
vent reduces resistance, increases efciency,
eliminates air noise and provides bass with supreme timing and the ultimate dynamic range.

PMC put over 25 years of experience into designing and
manufacturing the bass driver for the twenty5 series. The twenty5i range features the same high-specication bass units,
crafted to produce audio with the maximum possible drive,
resolution and detail, and minimum colouration. The driver cone is made from a custom resin-bound, ne-weave glass­bre composite to ensure maximum rigidity and strength —
conventional cones would simply crumple and deform when coupled to the ATL ultra-light, so it can respond instantly to changes in dynamics and also remains tonally neutral. With our ATL technologies, these drivers allow you to hear your music, not the loudspeaker.

The new twenty5i high-frequency driver, a 19mm SONOMEX soft-dome design, was derived from the high-frequency
unit on PMC’s premium fact speaker range; both were co­engineered with respected Norwegian driver manufacturers SEAS. The dome on the twenty5i range is mounted in the centre of a large roll surround, an arrangement which gives the effect of two drivers in one; it can produce the wide dispersion of a small-dome driver and the higher output of a larger driver.

DIVISION
WITH
PRECISION
The crossover is an essential component of any quality
loudspeaker, dividing the incoming audio from an
amplier into multiple signals with specic frequency
ranges best suited to reproduction by each of the loudspeaker’s drive units. During the design of the two-way twenty5i speakers, the crossover point where the tweeter hands over to the bass unit was lowered,
allowing the LF driver to focus more efciently on its core frequency range, while making sure the tweeter remains unencumbered by mid-range frequencies. The result is a more consistent, room-lling sound, with a wider sweet
spot.
The twenty5i models feature sophisticated crossovers with accurate lters mounted on military-grade bre-glass boards, ensuring that only the ideal frequency range is precisely routed to the correct driver. Thick, pure copper
tracks are used to connect the hand-selected crossover components to optimise signal delivery, and even the material of the crossover back plate has been carefully
considered. The brushed stainless-steel back panel is also
magnetically inert, preventing any adverse interaction with components.

DETAIL
Our holistic design philosophy means we consider every element of the loudspeaker’s design and its effect on performance.
BINDING POSTS
We design and make our own binding posts for perfect connectivity, machining and plating them with matte rhodium
for the best possible conductivity. They are directly coupled
to the crossover board to keep the signal path as short as possible.
GRILLES
The speakers’ elegant grilles are magnetically xed to the
cabinet, so there are no unsightly fastenings, and their slim-line
prole ensures they have no detrimental effect on the sound
of the speakers.
SPIKES

THE BEST,
BAR NONE
During the development of fenestria, our agship model, we established new and innovative ways to analyse vibration and how it affects loudspeakers. We found that if we were
to cancel or absorb specic frequencies, we could radically
enhance the audio performance and provide even greater levels of realism.
We have applied this knowledge to the twenty5i series by adding precision-engineered plinth bars that isolate the
speakers from the oor when combined with carefully specied damping materials. Decoupling the loudspeaker in
this way prevents unwanted energy being transmitted back to the drive units, so they remain completely focused. Our vibration analysis results show dramatic improvement, but
more importantly, the audio picture and denition are truly
astounding. Simply put, you hear less loudspeaker and more music.
We know what it takes to make great music. Our loudspeakers feature at every stage of the music-making process.

MADE IN THE UK WITH CARE
Our loudspeakers are designed and hand-built with care and
attention by fastidious people at the PMC facility in the UK,
where every single component is measured and graded. Every detail, from the individual elements on the crossover and in the drive units right up to the cabinet, is tested to ensure it meets our exacting standards for performance and reliability.
This ensures each new model is a duplicate of the reference
design.
A full computer analysis is taken for each completed
loudspeaker, so we know it is technically perfect — but we
go one step further. Computers don’t tell the full story, and
our customers listen with their ears — so we do too. We run a
benchmark BBC speech test and play an extensive array of
music (including classical, pop and rock) on each loudspeaker
we produce. Every one is compared with its reference model and both speakers in each pair are cross-checked to ensure
a perfect match. Such is the condence in our work that we offer an unparalleled 20-year warranty on all passive consumer
loudspeakers.
