Owner’s manual
Dear customer,
Thank you for choosing CA Electronics. Please read this manual fully before unpacking
and installing the product. It will help you to optimise its performance.
Environmental Information
All CA Electronics products are designed to comply with international directives on the
Restriction of Hazardous Substances (RoHS) in electrical and electronic equipment. We
only use FSC (Forest Stewardship Council) approved wood for the speakers, and painting
is done according to strict enviromental-friendly rules. The Glue used for building the
speakers is free from solvents.
Carton Contents
Check in the carton for:
1 Owner Manuel.
1 Speaker.
4 Adhesive feet.
Speaker Installation
The speakers are best used mounted on rigid floorstands that locate the speaker unit
approximately at ear level when seated. Shelf or wall bracket mounting is an option but it
provides less opportunity for optimising the sound through adjustment of speaker position.
If the speakers are to be placed on a shelf or furniture unit, adhesive pads may be
attached to the underside of the cabinet.
Speaker Positioning
Adjustment of speaker position following initial installation will probably further improve the
sound quality and is usually worthwhile. In either stereo or home theatre installations try to
ensure that the immediate surroundings of each speaker are similar in acoustic character.
For example, if one speaker is adjacent to bare walls while the other is adjacent to soft
furnishings and curtains, both the overall sound quality and the stereo image are likely to
be compromised.
To begin with, the speakers should be positioned between 1.5m and 3m apart at two
corners of an equilateral triangle completed by the listening area at the third corner. The
speakers should be approximately 0.5m away from the back wall, and at least 0.5m away
from any side walls.
Stray Magnetic Fields
The speaker drive unit create stray magnetic fields that extend beyond the boundaries of
the cabinet. We recommend you keep magnetically sensitive articles (television and
computer screens, computer discs, audio and video tapes, swipe cards and the like) at
least 0.5m from the speaker. LCD and plasma screens are not affected by magnetic fields.

Connections
All connections should be made with the equipment switched off.
Ensure that positive terminal on the speaker (coloured red) is connected to the positive
output terminal on the amplifier and that negative terminals on the speaker (coloured
black) is connected to the negative output terminal on the amplifier. Incorrect connection
can result in poor imaging and loss of bass. Ask your dealer for advice when selecting
speaker cable.
Fine Tuning
Before fine tuning, make sure that all the connections in the installation are correct and
secure.
Moving the speakers further from the walls will generally reduce the volume of bass.
Space behind the speakers will also help to create an aural impression of depth.
Conversely, moving the speakers closer to the walls will increase the volume of bass.
If the bass seems uneven with frequency this will most probably be due to resonance
modes in the listening room. Even small changes in the position of the speakers or the
listening position can have a profound effect on how these resonances affect the sound.
Try moving the listening position or locating the speakers along a different wall. The
presence and position of large pieces of furniture can also influence resonance modes.
If the central image lacks focus, try moving the speakers closer together or angling them
inward so that they point at a location just in front of the listening position. If the sound is
too bright, increasing the amount of soft furnishing in the room (heavier curtains for
example) may help balance the sound. Conversely, reducing the amount of soft furnishing
may help brighten a dull sound.
Some rooms suffer from “flutter echoes” – echoes that “bounce” between parallel room
boundaries. Flutter echoes can colour the sound of the speakers in the room. Test for
flutter echoes by standing in the middle of the room and clapping your hands. Flutter
echoes can be reduced by placing irregular shaped items or non-reflective surfaces,
bookshelves, rugs or pictures for example, on one of the offending walls or floor. Ensure
that the speaker stands are upright and firm on the floor. Use carpet piercing spikes if
appropriate and adjust them to take up any unevenness.
Running-in Period
The performance of the speaker will change subtly during the initial listening period. The
drive unit suspensions will loosen up during the first hours of use. The time taken for the
speaker to achieve its intended performance will vary. As a guide, allow up to a week of
average use. However, longer run-in periods (as long as a month) have been reported.
Aftercare
The cabinet surfaces usually only require dusting. If you wish to use an aerosol or other
cleaner, spray aerosols onto a cleaning cloth, not directly onto the product. Test a small
area first, as some cleaning products may damage some of the surfaces. Avoid products
that are abrasive, or contain acid, alkali or anti-bacterial agents. Do not use cleaning
agents on the drive units. Avoid touching the drive units, as damage may result. In order to
avoid the risk of the surface finish cracking, keep the product away from sources of direct
