Introduction
With the purchase of your CORNERED speakers, you can enjoy two things in one:
Unique design and excellent sound.
CORNERED speakers feature a one-of-a-kind 90-degree triangular design that makes
for a discreet and elegant installation anywhere in your home - in corners, on the wall,
below the ceiling, on shelves and as a center and rear channel for surround sound.
But good looks aren’t everything. CORNERED speakers also offers excellent sound
quality. In fact, CORNERED speakers reproduce a natural three-dimensional sound
stage that fills your room with sound – and strives at making listening to music one of
your favorite activities.
To get the most out of your CORNERED speakers – and make the installation process
as easy as possible – please take a minute to study this manual.
Enjoy!
Congratulations!
You are up for a great looking and great
sounding experience

1. Connect the cables
Note: It is important that you install the speaker cables BEFORE mounting your new
CORNERED speakers! The speakers are equipped with discreet cable terminals placed
on the front baffle behind the front cover – and it is not possible to run the cables to
the terminals once the speakers have been mounted.

PlacementInstallation guide
2. Find the perfect spot
Designed for versatile positioning
You’ve probably already found the perfect place for your new CORNERED speakers!
The speakers will fit vertically in a corner, horizontally between the wall and the ceil-
ing, above or below your TV as a center channel and of course behind your couch as
rear channels. If you don’t feel like mounting the speakers to the wall, you also have
the option of placing them like traditional speakers on a shelf or on top of a piece of
furniture.
Create a natural 3D sound stage
CORNERED speakers have a very wide dispersion of sound. To get the most out of
the speakers, we recommend as a rule of thumb that you place them with a distance
of minimum 2 meters and maximum 5 meters between the left and right speakers.
Avoid placing objects such as furniture between the speakers and the listening posi-
tion, as this will have a negative influence on the tonal balance of the sound. If you
take these few precautions, your new speakers will reproduce a natural 3-dimensional
sound stage – and give you a clear picture of each of the musicians and their position
on the stage.

Mounting in corners that are not exactly 90 degrees
Even if the corners in your home are not exactly 90 degrees, you can still mount your
new CORNERED speakers in the corner.
• Ifthecornerislessthan90degrees,simplyplacethespeakercabinetasdeepin
the corner as possible and use all four mounting points. This will leave a little space
behind the cabinet and the walls, but the speakers will still appear with a nice finish
in the corner
• Ifthecornerismorethan90degrees,werecommendmountingonlyoneofthe
sides of the speaker cabinet onto the wall – and leave some air behind the rear of
the cabinet. This will not be visible from the front, and the speakers will still present
themselves with a nice finish in the corner
Horizontal installation
If you wish to place the speakers horizontally away from the ceiling, you’ll need to
mount them onto a small bracket. Here’s how you do it:
• Removethefrontcover
• Placespeakersindesiredposition

Daily use of your
speakers
How to get the most out of your speakers
A powerful experience
There are many cool things about your new CORNERED speakers. Among others, they
can play very loud for their size and they are very reliable.
Choosing a suitable amplifier
Here’s the deal: Contrary to what many people think, a small amplifier is a greater risk
to the speakers than a big one! The reason being that a small amplifier, if pressed to
the limits, might become unstable and produce distortion or clipping.
This will increase the power more than 10 times to the tweeter, which may cause dam-
age. A large amplifier however, will remain in control while playing loud. As long as the
signal is clean, the speakers will have no problem receiving slightly more power than
they are specified for.
Important notes:
• Thetonecontrolsshouldbesetclosetotheneutralposition
• Ifyouheardistortionormechanicalsoundsfromthespeakers,chancesarethat
your amplifier is overdriven, and volume has to be turned down
• CORNEREDspeakershaveanominalimpedanceof8ohm–whichmakestheman
easy load for the amplifier and a great match for all quality amplifiers
Cleaning and maintenance
To keep up the good looks, clean the cabinet with a soft, dry micro-fiber cloth. The
front cover can be vacuumed and wiped carefully with a well-wrung, lint-free cloth
with a mild all-purpose cleaner. If you need to clean the speakers behind the front
cover, avoid wiping the dome tweeter as it can change the geometry of the dome and
reduce the sound quality significantly.
Disposing of electrical appliances
When eventually disposing of the product, do not mix it with general household waste.
There is a separate collection system for used electronic products in accordance with
legislation that requires proper treatment, recovery and recycling. Private households
in the EU member states, Switzerland and Norway may return their used electronic
productsfreeofchargetodesignatedcollectionfacilitiesortoaretailer(ifyoupur-
chase a similar new one). For countries not mentioned above, please contact your
local authorities for the correct method of disposal. By doing so, you will ensure that
your disposed product undergoes the necessary treatment, recovery and recycling
and thus prevent potential negative effects on the environment and human health.

Mounting the bracket

ProfessionalsInstallationguide
Installation
Before installing
As CORNERED top-boxes are very light, make sure that the wall structure is solid and
can support the weight of the speaker before installing the speaker. Also, make sure
that you comply with all local health and safety regulations.
A one-person job
The top-boxes are extruded in aluminum and therefore more compact and lighter
than a similar wooden cabinet. At the same time, the aluminum cabinet works as a
large cooling surface, thus reducing power compression significantly. The low weight
allows the products to be installed easily by one person. Drive units and crossover can
be easily accessed behind the front cover, which can be removed without tools in a
matter of seconds.
Safety wire
In installation terms, the CORNERED top-boxes are ‘as much brackets as they are
speakers,’ so no safety wire is needed, just as you don’t need a safety wire from the
wall to a bracket.
Coverage
Wide dispersion even at high frequencies
CORNERED speakers are designed with emphasis on uniform and wide power re-
sponse. Special emphasis is placed on phase through the crossover point and cone/
dome geometry. As an example, the large surround of the tweeter dome ensures very
wide dispersion also at high frequencies.

Recommended speaker cables
Speaker cables present the amplifier with different loads. Cables with high capaci-
tance, high inductance and high impedance have a strong negative influence on sound
quality as well as amplifier reliability. So in order to get the most out of the speaker
system, avoid using thin speaker cables.
Asaruleofthumb,2mm2(14AWG)cablecanbeusedforlengthsupto20meters.
4mm2(11AWG)cableshouldbeusedforlengthsover20meters.Forlengthsover
50 meters, some amplifiers will become unstable and sound quality and reliability
will be reduced significantly. Cornered speakers will allow for a 10mm cable to be
run through the cable tube, so if you use thick professional installation cable, simply
remove the outer isolation material from the cable and run the separate wires to the
speakerterminals(providedthecablewireshaveseparateisolation).Werecommend
the Cornered CSP2 speaker cable designed to fit in corners.
Easy load
Cornered speakers have high Re min., so they are an easy load. Typical pro amplifiers
will run three speakers per channel without problems.
Recommended amplifier
For professional applications we recommend amplifiers with a minimum output on
level with the highest recommended amplifier output in the specifications. If used with
asub,werecommenda24dBLinkwitz-Rileyhigh-passlterat80–100Hz.

Installation
Before installing
Make sure that the wall structure is solid and can support the weight of the speaker.
Also, make sure that you comply with all local health and safety regulations.
As the speaker is pre-angled, coverage can be adjusted by positioning the cabinet
higher or lower in the room - horizontally or vertically - until the desired coverage is
obtained. See below:
