INTRODUCTION
SPACE FIDELITY - THE MAIN BENEFITS
Captivatingly emotional sound
Space Fidelity creates a two-channel sound field
throughout the listening space. The entire room turns into a
stereo chamber, filled to the brim with music.
The sound image is the same everywhere in the
room
With conventional stereo systems, you only hear stereo
when you are inside an area of a few square metres
between and in front of the speakers.
Space Fidelity gives you a thrilling personal stereo
experience everywhere you go in the listening space.
Space fidelity's stereo is not focused in the centre of the
room at all. It follows you around, like the eyes of the Mona
Lisa. Wherever you go, you hear the same unique live
sound: Space Fidelity sound.
SETTING UP SPACE FIDELITY
Space Fidelity is very good-natured, and you can stand it
almost anywhere to enjoy superb sound. But if you want to
feel the full force of this exciting system, give it a little
'breathing space'.
• Give it one-and-a-half to three metres of free space on
both sides.
• Stand it off thirty centimetres from the wall.
• Then move back, sit back, and experience it. The most
exciting sound you ever heard.

SPACE FIDELITY - THE BACKGROUND
Surround sound systems try to produce realistic 3-
dimensional sound. But with five speakers, it demands
space, and is not always easy to fit into the room decor.
Because of this, various alternative solutions have
appeared. All aim to create a surround sound effect from a
compact, easy-to-handle source.
These systems invariably use side lobing from speakers.
The direct sound is minimized, and surround sound is
generated by reflections from the walls of the listening
space. This method can generate all-round sound, but
cannot by its nature reproduce clean stereo.
Space Fidelity is itself based on side-lobing. But it is not
dependent on wall reflections and therefore reproduces
natural, true-to-life sound.
For astereo channel, Space Fidelity produces a bi-polar
energy field that creates an air flow, equally powerful in
both directions, so, in effect, it creates circular sound
pressure fields.
Wherever you may be in the listening space, Space Fidelity
gives a much broader stereo sound sensation. Damping of
the walls does not detract from the live-performance quality
of the sound, and in certain circumstances may indeed
improve it.
Space Fidelity's acoustic tube creates precisely controlled
acoustical coupling between two conventional cone
loudspeakers, one for each stereo channel, at the opposite
ends of the tube.
Inside the tube, the nature and geometry of the damping
material (a bundle of very narrow evenly distributed
channels) absorbs and controls, to avoid the reflections.
This mutual interaction achieves wide-ranging freedom
from reflections and good level response over the full
frequency range.
As a result, the tube emits intrinsically synchronous wave
fronts, with precise phase relations. The sound is natural,
three dimensional and still free of blurring and loss of
definition.
