Philosophy

Quad has, since the 1950s, led the
field in loudspeaker development. The
famous Quad electrostatics are now,
quite rightly, regarded amongst the very
finest loudspeakers money can buy.

With a fifty-strong R&D team, our
research into acoustics and reproduction
leads the field in development of
quality hi-fi equipment. British design
and engineering coupled with the
industry’s most efficient manufacturing
facility combine to create products
unequalled in terms of value and
performance.

Our philosophy is simple - that of
producing ‘the closest approach to the
original sound…’.

Our philosophy is based upon a belief
that hi-fi should add nothing nor remove
anything from a recording – merely
reproduce it. The resulting sound
should be without artefacts, distortion,
colouration and truly revealing of the
recording process.

Buying a first Quad system is often
a revelation to customers. Although
neither artificially impressive nor
imposing, it will produce a natural
performance and an ease of listening
that is captivating from the start.

Quad products are sometimes seen as
the kind of products bought at the end
of a journey through hi-fi; we believe
they mark the beginning.

The Quad

4

The L- Studio active was born of Quad’s
desire to simplify high-performance and
to create the ideal amplifier module to
control what has become a reference
for its class.

Quad designed an amplifier module
to work in absolute synergy with
the L-series, compact enough to fit
within the confines of the cabinet, yet
powerful enough to deliver a full, rich
and detailed sound.

Designing an active speaker is really
the perfect foil for most loudspeaker
designers. Being able to correct acoustic
abhorations through equalisation is a
desirable objective. What though if the
speaker you are starting with is already
a class leader? What if it’s response is
already flat within 3dB from 20Hz to
over 20kHz.

The objective then is to deliver an
amplifier module which can fully
realise the capability of the loudspeaker.
To offer a clean signal path free
from lossy, long cable runs and be
perfectly matched to the impedance
characteristics of the loudspeaker.

At Quad we have taken this one stage
further. Each amplifier module contained
in each single speaker contains not just
one, but two amplifier modules.

A powerful and dynamic 60W amplifier
is used to control the bass driver whilst
a refined 40w amplifier controls the
high-frequency response. Simple high
and low-pass filters can be used on
each amplifier section to replace the
crossover and in-so-doing a revelation
occurs.

Not only is the bass fast and rhythmic;
the treble sweet and free from
constraint, the mid-band takes on a
new ‘fluid’ dimension, released from
congestion and phase interference, to
present vocals and complex harmonies
in a totally natural, detailed and layered
fashion.

The specification of one of the finest
loudspeakers of recent times combined
with four amplifiers per pair of speakers in
a horizontally bi-amped configuration is
remakable in itself, yet the performance
stands alone as justification enough for
these loudspeakers.

L-Studio active

The Quad

The original L-series entered hi-fi’s hall of fame in 2002,
with the 11L winning What Hi-Fi? magazine’s prestigious
‘Product of the Year’ Award – an accolade that was repeated
the following year, and again in 2004, winning best in
class. Around the world the pattern was repeated with
major awards from leading magazines on every continent.

Versatility

L

-Studio active

The L-studio active speakers are as
versatile in use as they are remarkable
in performance.

Having both standard RCA connectors,
and balanced inputs, they are fully
compatible with a wide range of source
components.

Whether it is a small MP3 player or
our own performance series 99CDP-2,
these loudspeakers will enable you to
get the most from your music.

Each loudspeaker has its own
independent volume control. By using
this to set the balance and overall
outout level, any source device with
a variable level volume can be used.
the 99CDP-2 is ideal for a high-quality
bedroom or kitchen system.

Coupled with a network music player,
they enable you to listen to your music
collection anywhere in the house ­without the quality restraints usually
involved in such systems.

Good Design

The theory of

According to Quad’s philosophy
a good loudspeaker should add
nothing, nor remove anything from
the recorded sound.

That’s fine in theory, but how can
we make sure that our loudspeaker
designs adhere to this principle?

The answer is both simple and
complex. Put simply, we manufacture
everything ourselves - that’s not we

make the cabinet ourselves and
buy in drive units - it’s not that we
make our own crossovers to tune
a ‘cobbled-together’ loudspeaker.

We manufacture every part of every
loudspeaker from raw materials:­Wood, metal, KEVLAR, rubber and
plastics.

We go further though. We manufacture
our own molds for die-casting, our
own tools for pressing and stamping

- and this is the real key to good
design.

Our designers and engineers have
complete freedom. If they want to
develop a new chassis - no problem;
if they want to experiment with new
materials - that’s fine. Because we
rely on nobody else, we can design
the complete product with complete
synergy - every part tweaked and
honed to form a perfect symbiotic
relationship with every other part.

That’s why, with Quad products the
whole is always much greater than
the sum of the parts.
