INTRODUCTION
Dear Customer and Music Fan
Congratulation on the purchase of
your new Revox fitted speakers. We
are grateful for the trust that you
have shown in our company through
your choice of these high quality
products.
Your Revox fitted speakers were
developed based on the latest in
acoustic know-how and were
manufactured with great care.
Before you start to use them, we
would recommend that you read this
manual thoroughly so that you will be
able to get the best sound results.
Unpacking
Please check that the all parts are
included before you start installation.
2 x Fitted speakers
2 x Metal grills
1 x Cut-out template
We recommend that you keep the
packaging material in case you
should need it in the future to
transport the speakers.
General
The Re:sound I inceiling 52 / 82 (ICS)
and inwall 52 / 82 (IWS) speakers are
designed to be installed in
suspended ceilings or in wall-
cladding. The integrated rotary
tensioner enables installation in
walls up to 32 mm thick.
Suitable fitted housings are available
from Revox if you want to install in
solid ceilings or walls. You will find
further information about Revox fitted
housings on Page 6+7.
Protective circuit
Both fitted speakers have a separate
protective circuit for the bass and
treble speakers, which reduces the
level of the speaker in the case of an
overload and reactivates it
automatically after a certain time. The
length of time is dependant on the
extend of the overload.
Magnetic fixture
The speakers offer a magnetic fixture
of the speaker grill, which reduces
the visible height to a minimum of 3,8
mm and in addition enables a very
easy installation.

Speaker position
General
Here are a couple of tips for you about
lining the speakers up, before you start
the installation. The speaker is
designed to achieve the optimum
reproduction if walls and room corners
are at least 0.5 meters from the
speaker. A shorter distance leads to
resonance in the bass ranges and to
booming effects.
There should be about 30 mm free
space to the side behind the fitted
opening so that the rotary tensioner
can be got into position (see
drawing).
Ideal fitting volume:
ICS 52 / IWS 52:  10 Liter (dm³)
ICS 82 / IWS 82 :  25 Liter (dm³)
Ducting warning
There shouldn’t be any loose ducting in
the fitting recess as these could vibrate
with the speakers. This would result in
a permanent background noise.
Large room speaker assignment
In the case of large rooms, we
recommend that you distribute
several speakers throughout the
room rather than just installing a
single speaker. Here, the total
impedance must be taken into
account. The possible switching
options of two or more speakers are
explained in the following chapter
The total impedance of speakers . The
important factors in relation to the
maximum volume are the membrane
cone area and the sensitivity of the
speaker, measured as dB per watt in
1m distance.
In general, the following rule is valid:
the larger the speaker and the
greater the amount of volume
available to it, the lower the deepest
limit frequency.
Usage as Home Cinema surround
speaker
The sound from the surround
speakers should be as diffused as
possible. As a rule, the speakers
should be positioned behind the
listener and at least 0.6 metres above
ear level. Ceiling installation in this
case leads to good results. The
positioning is less important with
surround speaker usage than in other
cases.

The total impedance of speakers
The total impedance when using
several speakers per channel
depends on the individual
impedances and the switching
option. The speaker switching
options are series and parallel. If the
total impedance is too low, causes
an overload of the amplifier (high
current) and causes the protective
circuit to be permanently activated. If
the total impedance is too high, the
amplifier is prevented from
damage(low current), but on the
other hand, maximum achievable
volume is very low and the speaker’s
full potential is not used.
As the impedance is the speaker’s
frequency-dependant resistor, Revox
recommends that you carry out a test
at the threshold of the permitted
speaker impedance.
Take note of the polarity of the
individual speakers with the various
switching options. The speakers should
always be of the same type, in order to
avoid variances in sound pressure and
radiation. If one or even more
speakers are connected with
reversed polarity, this results in a
significantly reduced bass
reproduction, together with an
imprecise and diffused sound
picture.

The parallel switching of 2 speakers

Result fig. 2
The parallel switching of 3 speakers
leads to a very low overall
impedance and is therefore not
recommended!

In the case of a new-build, we
recommend the use of the
corresponding, watertight fitted
housing from Revox. This is either fitted
in the wall at the building shell phase or
fixed to the boarding when sealing the
walls or ceiling.
The build-in housing from Revox
includes all the required parts:
1 x Wooden build-in housing
1 x Sound-proofing material
1 x Hinged cover
Inceiling 52 fitted housing
Part no.: 1.084.480.00
Sealing the fitted housing
The fitted housing is fixed to the
boarding with 4 nails at the pre-
drilled positions.
Flush mounting the fitted housing
If the fitted housing is to be flush
mounted in a brick wall, you must
ensure that the plaster coating that is
added later, is flush with the housing.

Speaker cabling
There is a round hole on the side wall
of the fitted housing which can take a
20 mm diameter cable duct (EN20
flexible ducting).
You must ensure that the joint
between the housing and the cable
duct is completely sealed and that no
concrete can penetrate from the
side.
Damping with sound proofing material
Revox recommends that the fitted
housing should be damped, through
the insertion of an even amount of
loosely-placed sound proofing
material. This increases the acoustic
volume and the speaker can
reproduce deeper frequencies. It
also reduces reflections on the rear
of the membrane, allowing the mid-
range reproduction to be clearer and
more natural.
Polyester fleece is suitable for use as
sound-proofing material, but you can
also use mineral wool or fibre glass.
The sound-proofing material is
included with the Revox build-in
housing.
Important:
You must make sure that the material
that you use in addition conforms to
local building and fire protection
regulations.

INSTALLATION
Info
The Re:sound I inceiling and inwall
speakers have integrated rotary
tensioners to enable quick
installation. These rotary tensioners
are located on the rear of the
speaker and swivel out through 90°
once the 4 marked screws (see
figure on the next page) on the front
of the speaker are screwed in.
Power should be switched off when
installing the speaker.
Installation
Step 1
Connect the speaker cable, with the
correct polarity, using the pluggable
screw connectors.
Step 2
Insert the screw connectors in the
corresponding socket, which is
located on the crossover board of the
speaker.
Step 3
Insert the fitted speaker into the
opening and tighten the 4 rotary
tensioner screws a little, until the
speaker flange is held in position at
the sides. Under no circum-stances
should the speaker flange be twisted.
Revox fitted housing:
Don’t forget the sound proofing
material.
Step 4:
In the last step the magnetic speaker
grill is attached to the speaker.

Adjusting speaker colour
Painting the speaker grille
You should remove the internal
fleece first, if the grill also is to be
painted. The fleece has an adhesive
surface, which allows you to put the
fleece back in position once the paint
has dried.
If the fleece does not adhere any
more, you can use a standard spray
adhesive.
Disassembling
Take off the speaker grill from the
frame with help of a flat object such
as a knife or similar. The frame with
the speaker grill can easily be
removed due to the magnetic fixture.
Hold the speaker in position and
unscrew the four fixing screws until
the head of the screw protrudes by
about 1 mm. The four rotary
tensioners are now back in the install
position and the speaker can be
removed.
Technical hints
Cable lengths
In order to keep the line and treble
loss as low as possible, we
recommend that you use the
following cable profiles and in any
case, you should use 2-core wire.
Up to 15 m: Ø 0.75 mm2
Up to 30 m: Ø 1.50 mm2
Over 30 m: Ø 2.50 mm2
Up to 50 ft: AWG 17
Up to 100 ft: AWG 14
Over 100 ft: AWG 12
We advise that you avoid using cable
lengths above 50 metres, in order to
avoid loss of hi-fi reproduction.
Load capacity
It is possible to operate these
speakers with amplifiers that have a
higher output performance. In this
case however, you must ensure that
the volume is only turned up to a
level where your ear (usually a
reliable measure) starts to notice an
overload.
Your Revox speakers will not be
damaged by a short-term overload.
