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. The company was
founded because there wasn’t a loudspeaker that was transparent
enough to convey all of music’s expressive power — and we knew
we could remedy this.
One of our core beliefs has always been that the same loudspeaker
can be used throughout the entire audio chain, from composer to
studio or lm stage, through post-production and mastering, right to
the listener at home. Discerning listeners all over the world agree. Our
designs are involved in every link of the music-making chain, from
the recording studio to listening at home, which means we know
exactly how to present music as transparently as possible, just as the
artist intended. This knowledge, combined with our love for music,
drives us to create products that you listen through rather than to. We
want you to share the thrill of the original recording because there
is nothing like the emotional impact of true musical communication.
Loudspeakers are where science meets art; we understand the
science so that you can connect with the art.

Oliver Thomas, Head of Design

A TRUE HERITAGE
Our Emmy®-award-winning systems are used in the world’s leading
studios so that engineers and artists can hear every nuance of their
work as they make the critical creative decisions. Our loudspeakers
are used to create everything from award-winning soundtracks to
successful albums by artists including Coldplay, Stevie Wonder,
Elton John and Adele, among many others. The list of Hollywood
composers using our speakers is equally impressive, and includes
the people who brought you 007’s Skyfall and SPECTRE, Iron Man,
Game of Thrones and the Bourne Supremacy, to name but a few.
PMC speakers deliver maximum transparency, so whether they are
in Los Angeles’ Capitol Studios or your living room, you will hear the
music exactly as the artist intended it. Only PMC can get you so
close to the original sound.

Advanced Transmission Line
All of our loudspeakers offer ATL
technology, which provides the following advantages
over ported speakers:
™
bass-loading
• More detailed, more natural
• Full, rich sound at any volume level
• Deeper bass from a smaller cabinet
• Easy to drive with all ampliers
ATL is an ingenious design and uses energy generated
by the bass unit in a much more intelligent, efcient way
than speaker designs based on ported or sealed boxes.
In ATL loudspeakers, the highly braced cabinet is lined
with a multitude of custom-designed acoustic materials
that absorb all but the very lowest frequencies. These exit
from a front-panel vent, extending the low-frequency
response, and creating the impression of a far larger
speaker with an extra, ultra-high quality bass unit.
ATL improves more than just the bass response: because
the low end is clean and clear, it doesn’t mask the rest of
the music. Vocals, in particular, are beautifully projected
and ultra-vivid.
ATL loudspeakers offer another benet. The ATL bass
extension does not change with volume level — so even
when listening quietly, the bass sounds balanced and well
dened.

OUR ATTENTION TO DETAIL
Our loudspeakers are designed and hand-built with care and
attention by people who are fastidious about quality. Such is the
condence in our work that we offer an unparalleled 20-year
warranty on all passive consumer loudspeakers.
All of our products are designed and built 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.
For over 25 years, PMC has built a reputation for making the nest
loudspeakers by maintaining this degree of attention to detail
at every stage of production, and on all of our loudspeakers,
®
including the entry-level twenty
series.
