Description
The Adagio series is a range of lightweight, elegantly shaped passive loudspeakers for installed
low-impedance and 100V line sound systems. Available in black and white and made from impact-
proof ABS plastic, they integrate cosmetically well with any environment and provide years of pleasant
appearance even in demanding ambient conditions. Fitted with high grade drivers fed through an
optimized crossover network, the Adagio series speakers offer pristine sound and excellent sensitivity
for superior use of amplifier power. A variety of mounting options are provided by two integrated
mounting points and a supplied bracket, making the Adagio series speakers a prime choice for the
retail, hospitality and fitness industries.
The Adagio series consists of five different models:
SMW420: 4.0” LF + 0.75’’ Mylar tweeter | 2-way passive | 8 Ω | 25W RMS
SMW420T: 4.0” LF + 0.75’’ Mylar tweeter | 2-way passive | 100V Line | 25W RMS
SMW620: 6.5” LF + 0.75’’ Mylar tweeter | 2-way passive | 8 Ω | 50W RMS
SMW620T: 6.5” LF + 0.75’’ Mylar tweeter | 2-way passive | 100V Line | 50W RMS
SMW820: 8.0” LF + 1.00’’ Dome tweeter | 2-way passive | 8 Ω | 85W RMS
The specifications for each model are available at the end of this user manual.

Setting up
A. Orientation, Distance
Due to the physical properties of the high frequency wave-guide, Adagio speakers, when placed verti-
cally upright, cover approximately 120 degrees in the horizontal plane and 60 degrees in the vertical
plane. In higher or larger rooms, where the mounting position is higher up on a wall, this will create a
high-frequency “shadow” close to the wall, where the music played sounds dull and muffled. To limit
this effect, it is recommended to mount the speakers horizontally instead of vertically in any mounting
position higher than 200cm. Since horizontal mounting however reduces the horizontal coverage, a
distance between speakers of not more than 200cm shall be obeyed, while in vertical mounting, up
to 400cm are permissible. If the wall which carries the speaker is longer, more speakers need to be
placed to achieve proper high frequency reproduction across the whole room space. Note that when
using mutiple low impedance speakers, total load impedance to the amplifier becomes a concern. See
chapter “wiring”.

B. Position
Background music systems often suffer from basic mistakes when being set up. While every room is
different and may require professional advice on best loudspeaker positions, a few rules are to be
obeyed:
Do not let speakers point at each other. Setups with one speaker in every corner of the room or
two rows of speakers on opposite walls are prone to prominent phase problems which can cause
audible modulation or unpleasent volume/sound changes while moving inside the room. In smaller
rooms, place all speakers on one wall. In larger rooms, choose a main wall (in rectangular rooms
possibly the longer one) where most speaker are installed and add speakers to the side walls, pointing
in the same direction as the speakers on the main wall. If speakers need to provide a sense of direc-
tion “where the sound comes from”, then choose the wall of the required direction (Bar counter with
DJ booth, stage with lectern) as the main wall.
Try to arrange speakers not to point at highly reflective surfaces. As an example, if a bar has a glass
facade, in many cases the actual bar counter is in the back with speakers left and right of it, facing the
glass facade. In fact, this is an unsuitable setup, since speakers facing the acoustically highly reflective
glass facade will create much unwanted reflection and sound coloration. A better set-up will have the
speakers mounted with the glass facade in the back, pointing to the bar counter.
Do not insist on stereo reproduction. While stereo sound systems provide a more refined listening
experience in a residental environment, they largely rely on a single and well specified listener position.
This is hardly the case in commercial sound systems, where shop clients move around and restau-
rant guests sit in many different positions. In such occasion, a mono sound systems may be preferra-
ble. If the feeding amplifier offers a mono switching option, engage this switch. If a stereo system is to
be installed, group multiple speakers in a side-separate manner, do not assign them one-over-another
to the stereo channels. Like with 4 speakers on a wall, the assignment shall be L-L-R-R and not L-R-L-R.

DANGER - risk of injury: Overhead installation requires extensive experience, like calculat-
ing working load limits, knowledge of installation materials, and periodic safety inspection
of all installation material and the installed product. If you lack such qualifications, do not
attempt the installation yourself. Improper installation can result in injury of people.
If the mounting location is not on a wall, but in an overhead position, please note:
The product must be installed out of reach of people and outside areas where persons may walk
by or be seated.
The installation area must be able to hold a minimum point load of 10 times the device’s weight.
The installation must be secured with an appropriate safety cable where necessary. Always use a
certified safety cable according to DIN56927 that can hold 12 times the weight of the device when
installing the unit. This secondary safety attachment should be installed in a way that no part of the
installation can drop more than 20cm if the main attachment fails.
The safety-relating and machine-technical installations must be approved by an expert before any
first-time operation.
The installation must be re-inspected every year.
C. Mounting
Since the specific requirements for installed sound systems may vary from country to country, it is
recommended to clarify the local requirements prior to installation. As a guide to good practice, the
following applies:
Speakers in commercial sound systems must be protected against displacement and hence must
be fixed in a specific position.
Do not place a loudspeaker without further fixation on top or inside of other objects (e.g. shelves)
Do not place a loudspeaker in any position where someone can sit, climb or stand on it.
Wherever possible, place speakers outside of reach for the public.
These speakers are not designed for outdoor use or any other use where splashing water, fog or
extreme humidity are to be expected.
Only use the supplied bracket for mounting.
Always use all provided holes in the bracket for secure mounting.
Mounting has to be expedited on an even surface. The surface material’s supporting structure has
to withstand up to 5 times the load of the speaker without any fatigue or deformation.
Mounting materials (screws, wall plugs/anchors) must be chosen to match the nature and struc-
ture of the mounting surface and its supporting construction, and must be plated for provision
against corrosion.
Follow the below procedure for mounting:
Fix speaker by inserting top/bottom screw handles Adjust position as desired
Mount bracket with
screws to wall

E. Wiring
Before connecting your Adagio speakers, please take the necessary safety precautions, and prepare
the proper cable materials. If you connect more than one speaker to an amplifier output, make sure
that the load impedance of the combined speakers is in accordance with the amplifier’s load imped-
ance handling capability. See section F of this chapter for suitable multi-speaker configurations.
Cable Choice
The choice of suitable speaker cables is often a neglected but at the same time essential point of a
sound system installation. Speaker cables, specifically long ones, can significantly contribute to the
load impedance of the amplifier, thus reducing the power output and turning some of the output
power into heat instead of delivering it to the speakers. The most important aspect is to keep cables
as short as possible and to choose a sufficient copper cross-section, with maximum length values as
per below (based on 1 dB allowed level drop or 11% voltage loss in the return loop):
DANGER - risk of electric shock. Audio power amplifiers can generate output voltages in
excess of the limits considered harmless to the human body. Initial cabling or any modifica-
tion of cabling shall only be expedited with all amplifiers switched off.
DANGER - risk of fire. Audio power amplifiers may not be secured against output shortcir-
cuits and may be damaged if such short circuit occurs, with such damage potentially lead-
ing to a fire hazard. Any cabling activity bears the danger of unwanted, temporary short
circuits. Initial cabling or any modification of cabling shall only be expedited with all amplifi-
ers switched off.
D. Connections
The speaker has two screw terminals on its backside, which are color coded in red (+) and black (-).
Most likely, the amplifier output features a similar color coding, or at least an indication of (+) and (-).
Make sure the amplifier is switched off, choose an appropriate loudspeaker cable and connect the
red (+) output of the amplifier with the red (+) input of the speaker, and the black (-) output of the
amplifier with the black (-) input of the speaker. To grant a secure connection on the speaker side, turn
the locking cap of the speaker terminal counter-clockwise to its highest position, insert the cable (with
its last 12mm stripped of any insulation) into the via hole of the terminal thread bolt and screw the
locking cap back clockwise until it securely locks the cable in place.

F. Multi Speaker Configurations
Connecting mutiple speakers to a single amplifier output allows to sonically cover larger areas with a
minimum of extra hardware. Dpending on whether you use a low-impedance or a 100V line version
(suffix T) of the Adagio range, some rules need to be obeyed when connecting mutiple speakers:
For low-impedance systems, since cable impedances add into the total system impedance, attention
must be paid to choose appropriate copper cross sections according to the cable length (see table).
Further, all speakers must be connected with approximately the same cable length, to avoid different
sound levels. The best is to make a star point with a distribution box in the geometric centre of a
speaker group and connect the amplifier to this star point with a cable of large cross-section, then the
speakers with cables of same length to the same star point. Depending on the arrangement, the total
speaker array may have a lower, same or higher impedance than a single speaker. Avoid load imped-
ances below 4 Ohms. Some recommendable configurations are shown below, per amplifier channel:

G. Operation
Following a proper power-up sequence as per below protects your equipment, speakers and ears:
Turn down all output volume controls of any equipment in your audio system.
Switch on your audio sources first (Media Players, Mixers), then switch on any amplifiers
Turn up the level on your sources to less than half, then turn the amplifier volume slowly up.
Make adjustments to all volume settings as needed.
Be aware that excessive volume levels exceeding 90dB for longer time may cause hearing damage.
If any distortion is audible, the level settings are either incorrect or too much power is supplied to
the speakers. Correct the level matching or overvall level to avoid damage to the speakers.
For switching off, follow the inverse sequence – switch off your amplifier(s) first, then the sources.
For high-impedance systems, cabling can be of smaller cross section (see
table) and is a very straighforward parallel connection to one feeding line:
