Congratulations on your new Ci loudspeaker system from Blaze Audio.
The Ci series is a feature packed range of loudspeakers designed for use in a large variety of
applications. Emphasis is placed on discreet modern design, ease of installation, wide and uniform
coverage and excellent sound quality without the use of electronic signal processing.
Included in the box:
Two speakers
Mounting screws
Mounting template
Safety letter
The series provides 100 degree vertical x 100 degree horizontal dispersion and comprises 2”, 4”, and 5”
models, with an optional high-impedance mode. The patented 90° triangular ABS cabinet with built-in
sliders (available on the 4” and 5” models only) not only ts perfectly into vertical and horizontal corners
without showing visible brackets, but also offers a variety of unique placement options. These include
coupling 2-3 speakers together to increase coverage to 180 or 270 degrees when mounted on walls,
ceilings, or free-standing corners (the Ci2 allows a maximum of 2 coupled cabinets for 180-degree
coverage).
For enhanced bass performance, the Ci series can be teamed indoors with our C8S and C12S
subwoofers.
Introduction
How to connect the cables.
The Ci2 model is tted with spring loaded terminals on the front bafe. Contacts will accept up to 2,0
sq. mm wire with an outside diameter of up to 8 mm.
Note: It is important that you run the speaker cables through the port BEFORE installing your new
Blaze Audio speakers! The speakers are equipped with discreet cable terminals placed on the front
bafe behind the front cover – and it is not possible to run the cables to the terminals once the speakers
have been installed.
Getting started
1
2
Remove the front cover to access the cable terminal:
Push the cover from the side of the cabinet to squeeze
it out of the grove.
Make sure the amplier is turned off.
3
Run the speaker cable through the tube positioned at the
rear of the cabinet to the terminal at the front bafe.
Note that it is easier to install the speaker rst and mount
the cable to the terminal after the speaker is mounted to
the wall.
Connect the cable to the terminal after the
speaker is mounted to the wall.

The Ci series can be mounted either in corners or on walls and ceilings with the integrated mounting
points. They can also be coupled together to extend coverage.
The Ci2 is very light, but please make sure that the wall or ceiling is solid and can support the weight of
the speaker before installing. Also, make sure that you comply with all local health and safety regulations
(See the Safety Letter included in the packaging). The low weight allow the products to be installed easily
by one person.
Vertical or horizontal installation in corners.
If you prefer to mount the speaker in a corner, you should:

• Drill holes in the wall using 4 mm rawl plugs and the enclosed 3,5 mm at head screws.
• Reposition the speakers in desired position and mount the screws.
Mounting in corners that are not exactly 90 degrees:
• If the corner is less than 90 degrees, simply place the speaker cabinet as deep in the corner as
possible and use all mounting points. This will leave a little space behind the cabinet and the walls, but
the speakers will still appear with a nice nish 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 other side of the cabinet. This will not be visible
from the front, and the speakers will still present themselves with a nice nish.

Remove the front cover and you’ll see the
mounting holes on the front of the cabinet.
Place the mounting template in desired position
and mark drilling positions by shading through
the two mounting holes
When you have installed the speaker to the wall or ceiling,
then connect the speaker cable to the terminal and reinstall
the front cover.
Connect the red (+) speaker cable to the red cable terminal
and the black (-) speaker cable to the black speaker terminal.
Mounting the cabinets together
Our Ci series speakers are designed with an emphasis on uniform and wide controlled dispersion.
The acoustic design allows the speakers to be coupled together to expand coverage:
• One Ci cabinet offers 100x100 degree dispersion.
• Two Ci cabinets can be coupled together back to back and then mounted ush onto walls and ceilings
while offering 200 degrees of coverage with minimum phase cancellation.
If you wish to mount the speakers together, simply mount the speakers back to back on wall or ceiling
using the integrated mounting points as shown below:
Two Ci2’s mounted back to back.
Cables
Speaker cables present the amplier with different loads. Cables with high capacitance, high inductance
and high impedance have a strong negative inuence on sound quality as well as amplier reliability. In
order to get the most out of the speaker system, avoid using thin speaker cables.
As a rule of thumb, 2 mm
2
(14 AWG) cable can be used for lengths up to 20 meters. 4 mm
2
(11 AWG)
cable should be used for lengths over 20 meters. For lengths over 50 meters, most ampliers will
become unstable and sound quality is reduced signicantly.
To minimize power loss and response variations, please refer to the following table for guidance,
showing the maximum recommended cable length relative to impedance and cable thickness:
Outdoor mounting.
The Ci2 speaker is IP64 rated, so it can be placed outside (See the Safety Letter included in the
packaging). If installed outdoors, the insulation of the cabling should be resistant to water as well as the
effects of temperature and ultraviolet radiation from the sun. Recommended insulations are:
UV stabilized polyethylene, neoprene, Teon™, Silicon™, and Hypalon™.
The following materials are not recommended, because of potentially shorter life expectancy in outdoor
environments: Rubber, PVC (polyvinylchloride), polypropylene, polyurethane, and nylon. UV-stabilized
polypropylene may be acceptable.
Safety wire.
In installation terms, the top-boxes are as much brackets as they are speakers, because they mount ush
to the walls and ceilings, so no safety wire is needed (just like on traditional speaker installations, you
don’t use a safety wire from a bracket to the wall).

Operation

Recommended loudspeaker presets are available at blaze-audio.com/support and are designed for use
with Blaze Audio’s PowerZone™ Connect DSP-enabled amplier series.
Recommended amplier.
The Ci speaker series has a high minimum impedance, making them an easy load for ampliers. We
recommend using Blaze Audio’s PowerZone™ Connect DSP-enabled ampliers with power ratings that
exceed the loudspeakers’ power handling capacity (see specications). As with all loudspeaker systems,
power handling depends on the quality and size of the amplier. If the amplier is overdriven and runs
into clipping, the drivers can be damaged, even if the amplier’s output is lower than the speaker’s
power handling capacity. When selecting an amplier, keep in mind that a higher power amplier
operating without distortion will typically sound better and cause less damage to the loudspeaker than a
lower power amplier that is constantly clipping.
Break-in time.
As with all quality loudspeakers, your Ci2 has to play for approximately 30 hours before performing to
specication.
Warranty.
For warranty information, please refer to your local Blaze Audio distributor or dealer, or contact us
directly.
Service.
Woofers can be easily replaced by unscrewing them from the bafe using a Hexagon H3 bit. The
tweeter is clicked into the horn section of the bafe from the rear of the bafe. To access the tweeter,
remove the bafe by unscrewing the four Philips screws.
Spare parts for your Blaze Audio speakers are available through your local Blaze Audio distributor or
dealer. Please contact us directly, in case you are not able to source spare parts locally.
Turn the tweeter counter-clockwise to remove
it from the bafe. Reinstall the new tweeter by
pressing it towards the horn section of the bafe
and turn it clock wise until you hear a “click”.
The crossover is removed by unscrewing the
Philips head screws and removing the cables from
the drivers.
