Absolute Zero has been designed
by audio guru Trevor Stride, the
man behind the acclaimed
Absolute 2 monitor.
Trevor has over 15 years of
audio design experience behind
him, working for a number of the
industry’s leading names, including
SSL and Focusrite.
Trevor’s design philosophy
behind the Absolute Series is
deceptively simple:
• Any professional monitor should exhibit an even
frequency response at high and low levels, on
and o axis;
• it should have the most natural, uncoloured sound
possible, whatever the price level;
• it should not exagerate or enhance sound;
• it should not cause listening fatigue (often arising
from the inappropriate use of driver materials that
produce spurious resonances masking the monitor's
true sound);
• it should be reliable in prolonged, professional use.
To satisfy these criteria, Trevor has scrutinised every
element of Absolute Zero’s design to optimise its
performance.
The sturdy, vented cabinet design complements
the 170mm low-frequency driver to give smooth,
extended bass response and the soft-dome
tweeter is mounted in a proprietary waveguide to
ensure controlled dispersion.
In the tradition of all good monitors, the wide
frequency response remains even at all listening
levels, both on and o axis - so you can be
assured of consistent, dependable results
every time. Furthermore, special attention has
been paid to the impulse response of the system
in order to give the most natural, uncoloured
sound possible.
Absolute Zero oers superb all-round
performance, is remarkably versatile and comes
at a price that is truly aordable.

THE INSIDE STORY
The Tweeter
Absolute Zero’s tweeter is a custom-
designed catenary-profile soft dome
unit which exhibits all the extended
high frequency characteristics of
standard metal dome tweeters, without
sharing any of their harshness. The
tweeter is recessed to help protect it
from surface impacts.
The Bass Driver
Absolute Zero uses a new 6.5"/170mm
bass driver with a 30mm voice coil,
providing extended bass response
with high power handling capability.
The Waveguide
Absolute Zero’s proprietary wave-
guide serves to “time-alignits
tweeter with its bass driver, and to
restrict the tweeter’s dispersion to a
90° angle. This reduces cabinet-
edge diraction and the risk of
acoustic feedback in sound
reinforcement applications, whilst
increasing high frequency power
handling.
The Port
Many monitors utilise deep port
designs positioned at the front of
the cabinet, which can cause mid-
range response to vary by as much
as 6dB. Absolute Zero’s deep port
is rear facing, guaranteeing
midrange consistency.
The Cabinet
Many small cabinet speakers suer
from diffraction problems in the
upper-mid frequencies caused by
sharp vertical edges. In contrast,
Absolute Zero’s vertical edges are
contoured to minimise diraction
from reflected sounds.
The Connectors
Poor quality connectors are often
the weakest link in the signal path,
reducing signal quality from
amplifi Absolute Zeroer to speaker.
uses only top-grade gold plated
binding posts which give better
contact for many years.
Custom Components
Many of Absolute Zero’s components,
including its tweeter and bass driver,
are exclusive to Spirit to ensure that
performance is not compromised
by the use of o-the-shelf designs.
USING ABSOLUTE ZERO
The in-line driver array, with its
wideangle tweeter, means that
Absolute Zero may be used
horizontally or vertically. With
flat response up to 30° o-axis,
speaker angle is less critical than
with many monitors. In addition,
the rear-ported design not only
makes for a smaller front baffle
area but also allows the speaker
to be used in mid-room
positions.
Absolute Zero is rated at 95
Watts RMS but its high quality
design permits the use of more
powerful amplifiers, albeit with
caution.
The sturdy, recessed binding
posts will accept bare wires, 4mm
‘banana’ plugs or 6 forkmm
terminals.
Most tweeters have a wide
dispersion angle
Absolute Zero’s
tweeter is more
efficient because it
has a narrower
dispersion angle

CONTROLLED DISPERSION
Accurate monitoring is all about
hearing a faithful rendition of
your programme material. But
sometimes your judgement can,
quite literally, be ‘coloured’ by
the environment in which you’re
working. High frequencies from
wide dispersion tweeters can
reflect o nearby surfaces,
creating unwanted echoes. In
imperfect or untreated acoustic
environments, it is useful to
control dispersion.
Absolute Zero’s controlled
dispersion
of high frequencies
means you hear more
of your
music and less of your room.
