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.
• One cabinet offers app 90x90 degree dispersion. Cabinets can be coupled to
gether to increase coverage
• Two CORNERED cabinets can be coupled together back to back and mounted
flush onto walls and ceilings while offering 180 degrees of coverage with minimum
phase cancellation between the cabinets
Notes for the
professional installer
•
Three cabinets can be mounted together around a corner, offering 270 degree
coverage
•
And four cabinets can be mounted together and hung from the ceiling, offering
360 degree of dispersion
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 filter at 80 – 100 Hz.
