5. INSTALLATION
Read these instructions carefully before installing and using the product.
• When installing in-wall/in-ceiling loudspeakers, be aware of the weight of
your particular model (see “8. TECHNICAL PARAMETERS” at page 12 for
the weight) and the sturdiness of the material into which you are installing the
speaker. Also, be aware of any concealed studs, electrical wiring or plumbing
in the wall or ceiling into which you are installing the speakers.
• Do not use nails, adhesives or other unauthorized devices. Long-term use
and vibrations may cause it to fall easily.
• If you plan to install your speakers where water will directly contact them, it is
advisable to use a silicone sealant or caulk between the frame of the speaker
and the wall surface. This seal should prevent water from getting behind the
loudspeaker and possibly damaging the wall surface.
• Do not position the speaker where water can pool on the surface of the
woofer cone or tweeter dome, as this will great decrease the speaker’s useful
life (and everything will sound ”glub! glub!”, like it’s coming from under wa-
ter).
ONDA Series speakers are IP54 speakers. Please be noticed before
installing the speaker.
• Do not place the speakers on movable supports.
• Do not touch or bump the woofer. If these are damaged, the sound will be
distorted.

ONDA Series
Quick-Mount Hi-Fi Coaxial In-Wall/In-Ceiling Speakers

• Do not listen to sound at a very high level when you are changing the input
source (for example, from FM Tuner to CD player). Please be sure the power
amplier is turned o or master volume is at lower level.
• Do not attempt to clean the speakers with chemical solvents as this may
damage the paint surface. Clean with a dry cloth.
5.1. Speaker Installation
“Out of the box and into the wall”, that is how easy it is to install ONDA series
loudspeakers.
If you intend to do the installation yourself, we recommend that you possess
some skill in the proper use of hand and power tools. You should have a thor-
ough understanding of local building and re codes and a familiarity with the area
behind the wall or ceiling into which you plan to install your speakers.
The installer is responsible of installation. Please pay attention to
install speakers according to local safety regulations. If you are not
sure to install in a safe way these speakers, consult a professional
installer, your authorized dealer, or a contractor.
Things you will need:
yPencil for marking the location of installation;
yKeyhole saw, utility knife or material appropriate incising implement for cutting
drywall or other wall material
yLevel
yScrewdriver (preferably powered)
yPower drill with appropriate bit (optional, for starting wall cut)
Steps to be followed:
1. Make sure the material into which you plan to mount the speaker (plaster, dry-
wall, paneling, stone, etc.,) supports the weight of the speakers (see “7. IN-
WALL/IN-CEILING SPEAKER PAINTING” at page 10 for the weight of each
model).
2. Make sure the locations you select do not conceal studs, electrical wiring or
plumbing. Prior to installation, hold the speaker in your chosen location to make
sure it safely clears obstacles such as studs, corners, beams, lighting xtures and
door/window frames. Your cutout must be at least 1” (25mm) from adjoining
walls or ceiling, internal studs or plumbing.
3. Draw a ceiling hole on the wall or ceiling with a diameter corresponding to the

ONDA Series Quick-Mount Hi-Fi Coaxial In-Wall/In-Ceiling Speakers
8
ones shown on “4. PRODUCT APPEARANCE” at page 5.
4. Carefully cut the hole with the appropriate cutting tool for your wall or ceiling
material. Start the hole by drilling a hole on the inside of the tracing (with the
drill bit touching the line). Use this hole to insert the saw or knife and begin
cutting.
5. Remove the magnetic speaker grille.
6. Once you have cut the hole, sh your previously positioned wiring out of the
hole and connect the speaker. Strip about 2” (12 mm) of insulation from each of
the two conductors of the wire to expose the bare metal and twist each of the
conductors into a single unfrayed strand (so you have two unfrayed strands).
Note that one of the two terminals on the rear of each speaker is red (+) and
the other is black(-). Make certain that you connect the wire from the red ter-
minal (+) of your amplier or receiver to the red terminal (+) of your speaker,
and the wire from the black terminal (-) of your amplier to the black termi-

ONDA Series
Quick-Mount Hi-Fi Coaxial In-Wall/In-Ceiling Speakers
9
nal (-) of your speaker. Most wire has some indicator (such as color-coding,
ribbing or writing) on one of the two conductors to help you maintain consis-
tency.
7. Loosen the rotating clamps by unscrewing them. Make sure that they are
ipped inwards so that your speaker ts into your cutout without nicking your
wall. Then place the speaker carefully into the cutout.
If you have a level, use it to help you correctly align the speaker. Tighten the
wall clamp screws with a screwdriver. This will rotate the wall clamps and se-
cure the speaker to the wall.
HINT: do not over-tighten the wall clamp screws!
8. Carefully reinstall the grille.
6. UNDER-POWERING VS OVER-POWERING
Most speaker damages are caused by ampliers with too little power (wattage).
Overdriven ampliers clip output waveforms and send distortion to the speakers.
Clipping is usually audible; it may vary from a harsh sound to a fuzzy or unclear
sound.
If you hear this condition at loud volume levels, turn down the amplier volume
until the distortion is no longer present. Damages caused by operating the speak-
ers at distorted volume levels are no covered by warranty.

7. IN-WALL/IN-CEILING SPEAKER PAINTING
You will need:
yPaint of your choice (to make the job easier, we recommend spray-painting the
grille)
yMasking tape and/or paper
Preparing to paint:
When painting the frame of the speaker, carefully mask o the front of the
speakers to protect the drivers and baes while painting. You can do this while
the speaker is already installed in the wall (if, for instance, you are repainting the
room). Carefully mask the speaker components using paper and masking tape.
Painting the frame:
1. Apply paint to exposed (unmasked parts). Use two or more thin coats. Spray
painting is recommended.
Mask the drivers and baes, and then spray part in thin coats

ONDA Series
Quick-Mount Hi-Fi Coaxial In-Wall/In-Ceiling Speakers

2. When the paint is completely dry, remove the masking material.
Painting the grille:
3. Grilles must be spray-painted. Do not use a brush and paint. Thick, brushed
paint may clog the grille holes.
4. Before spray-painting the grille, carefully remove the grille’s fabric scrim by
peeling it away from the inside of the grille. Place this on a clean, at surface
where it will not be wrinkled.
Peel away fabric grille scrim before painting the grille
5. After removing the grille by carefully hooking it with a bent paper clip and
pulling it gently away from the frame, spray on two thin coats of nish color.
If you are using a compressor and spray gun, use the nest, most diuse
setting. Be careful not to ll the holes in the grille with paint.
Paint the grille. Use thin coats of spray paint. Do not block grille holes with paint.
6. When the grille is dry, carefully press the fabric scrim back into place on the
inside of the grille. The special fabric scrim hides the speaker’s drivers from
view, and not interfere with the sound.
7. When the paint is completely dry, carefully reinstall the grille by tting it into
its recess so that it is just resting on the frame. Starting with one corner, go
around the speaker and push the grille into the grille notch a little bit at a
time. Be gentle; the grille may be easily bent out of shape by rough handling.
You will feel a positive “snap” when it is fully in place.

3. DESCRIZIONE DEL PRODOTTO
La serie di diusori a incasso ONDA nasce per soddisfare tutte quelle installa-
zioni da interno dove sono richieste pressioni sonore e qualità audio superiori
ai normali sistemi di diusione a 70/100V. I diusori ONDA sono tutti a bassa
impedenza (8ohm), coassiali, con woofer in kevlar, tweeter con cupola in seta,
crossover di precisione; in sostanza dei veri e propri diusori a 2-Vie per appli-
cazioni professionali ma in formato da incasso. Il look della supercie frontale è
minimalista e accattivante, e richiama quello dei monitor di riferimento da studio
di registrazione. Il design frame-less, con telaio in ABS nero e griglie magnetiche
bianche, rende i diusori ONDA estremamente discreti. Le griglie, inne, possono
essere riverniciate per renderle ancora meno visibili.

5. INSTALLAZIONE
Leggere attentamente queste istruzioni prima di installare e utilizzare il prodotto.
• Quando si installano altoparlanti a parete / a sotto, prestare attenzione al
peso del proprio modello particolare (vedere “8. PARAMETRI TECNICI” a pagi-
na 12 per il peso) e alla robustezza del materiale su cui si sta installando l’alto-
parlante. Inoltre, prestare attenzione a eventuali perni nascosti, collegamenti
elettrici o idraulici nella parete o nel sotto in cui si installano gli altoparlanti.
• Non utilizzare chiodi, adesivi o altri dispositivi non autorizzati. L’uso a lungo
termine e le vibrazioni possono far cadere il diusore facilmente.
• Se si prevede di installare i diusori in modo che l’acqua entri in contatto di-
rettamente, è consigliabile utilizzare un sigillante siliconico o un sigillante tra
il telaio del diusore e la supercie della parete. Questo isolamento dovrebbe
impedire all’acqua di penetrare dietro l’altoparlante e danneggiare eventual-
mente la supercie della parete.
• Non posizionare l’altoparlante dove l’acqua può accumularsi sulla supercie
del cono del woofer o della cupola del tweeter, poiché ciò ridurrà notevol-
mente la vita utile dell’altoparlante (e tutto suonerà come se provenisse da
sott’acqua).
I diffusori della serie ONDA sono altoparlanti IP54. Si prega di tenere
a mente questa informazione prima dell’installazione.
• Non posizionare gli altoparlanti su supporti mobili.
• Non toccare o urtare il woofer e il tweeter. Se questi sono danneggiati, il
suono sarà distorto.
• Non ascoltare l’audio a un livello molto alto quando si cambia la sorgente di
ingresso (ad esempio, dal sintonizzatore FM al lettore CD). Assicurarsi che
l’amplicatore di potenza sia spento o che il volume principale sia al livello più
basso.
• Non tentare di pulire i diusori con solventi chimici in quanto ciò potrebbe
danneggiare la supercie della vernice. Pulire con un panno asciutto.
5.1. Installazione del Diffusore
“Direttamente dalla scatola al muro”, questo è il modo più semplice per descrivere
la facilità di installazione degli altoparlanti ONDA.

Serie ONDA Diffusori Hi-Fi Coassiali da Incasso a Montaggio Rapido
20
Se si intende eseguire l’installazione da soli, è necessario possedere alcune abilità
nell’uso corretto degli utensili manuali e elettrici. Dovresti avere una conoscenza
approfondita dei codici di colore usati negli impianti elettrici e antincendio locali,
e sapere cosa c’è dietro il muro o il sotto in cui intendi installare i diusori.
L’installatore è responsabile della corretta messa in opera dell’im-
pianto. Prestare attenzione all’installazione degli altoparlanti secon-
do le norme di sicurezza locali. Se non si è sicuri di installare questi
diffusori in modo sicuro, consultare un installatore professionista o
un rivenditore autorizzato.
Materiale Occorrente:
yMatita per segnare il luogo di installazione;
ySega da traforo, taglierino multiuso o attrezzo per incisione del materiale adatto
al taglio di pareti a secco o altro materiale per pareti.
yLivella
yCacciavite (preferibilmente avvitatore)
yTrapano elettrico con punta appropriata (opzionale, per iniziare il taglio della
parete)
Passaggi da seguire:
1. Accertarsi che il materiale su cui si prevede di montare l’altoparlante (intonaco,
muro a secco, cartongesso, pietra, ecc.) supporti il peso del diusore (vedere
XXXXXXXXXX per il peso di ciascun modello) .
2. Assicurarsi che dietro il punto selezionato non passino cavi elettrici o tubi o vi
siano altri impedimento. Prima di forare, vericare che l’altoparlante nella posi-
zione scelta non incontri ostacoli come, angoli, travi, apparecchi di illuminazio-
ne e cornici di porte/nestre.
3. Disegna un foro sul sotto sulla parete o sul sotto con un diametro corrispon-
dente a quelli mostrati su “4. ASPETTO DEL PRODOTTO” a pagina 18.
4. Realizzare con cura il foro sul muro o sul sotto con la sega da traforo. Inizia
il ritaglio praticando un foro all’interno della traccia (con la punta che tocca il
