Introduction

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 fits 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.

Getting started

How to connect the cables.
The Ci2 model is fitted with spring-loaded terminals on the front baffle. 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 baffle behind the front cover, and it is not possible to run the cables to the terminals once the speakers have been installed.
1. Remove the front cover to access the cable terminal: Push the cover from the side of the cabinet to squeeze it out of the groove
2. Make sure the amplifier is turned off.
3. Run the speaker cable through the tube positioned at the rear of the cabinet to the terminal at the front baffle.
  Note that it is easier to install the speaker first and mount the cable to the terminal after the speaker is mounted to the wall.
4. Connect the cable to the terminal after the speaker is mounted to the wall.

Installation

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 allows 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:
1. 1 Remove the front cover, and you’ll see the mounting holes on the front of the cabinet.
2. Place the mounting template in the desired position and mark drilling positions by shading through the two mounting holes
Drill holes in the wall using 4 mm rawl plugs and the enclosed 3,5 mm flat head screws.
Reposition the speakers in the 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 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 leaving 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 finish.
When you have installed the speaker on 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 100×100 degree dispersion.
Two Ci cabinets can be coupled together back to back and then mounted flush 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 wthealwallr ceiling using the integrated mounting points as shown below:

Cables

Speaker cables present the amplifier with different loads. Cables with high capacitance, high inductance, and high impedance have a strong negative influence on sound quality as well as amplifier reliability. In order to get the most out of the speaker system, avoid using thin speaker cables.

As a rule of thumb, 2mm²2 (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, most amplifiers will become unstable, and sound quality is reduced significantly.
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:

Operation

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, Teflon™, 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 flush 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).

Speaker presets.
Recommended loudspeaker presets are available at blaze-audio.com/support and are designed for use with Blaze Audio’s PowerZone™ Connect DSP-enabled amplifier series.

Recommended amplifier.
The Ci speaker series has a high minimum impedance, making titan easy to load for amplifiers. We recommend using Blaze Audio’s PowerZone™ Connect DSP-enabled amplifiers with power ratings that exceed the loudspeakers’ power handling capacity (see specifications). As with all loudspeaker systems, power handling depends on the quality and size of the amplifier. If the amplifier is overdriven and runs into clipping, the drivers can be damaged, even if the amplifier’s output is lower than the speaker’s power handling capacity. When selecting an amplifier, keep in mind that a higher power amplifier operating without distortion will typically sound better and cause less damage to the loudspeaker than a lower power amplifier that is constantly clipping.

Break-in time.
As with all quality loudspeakers, your Ci2 has to play for approximately 30 hours before performing to specification.

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 baffle using a Hexagon H3 bit. The tweeter is clicked into the horn section of the baffle from the rear of the baffle. To access the tweeter, remove the baffle 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 baffle. Reinstall the new tweeter by pressing it towards the horn section of the baffle and turn it counterclockwise until you hear a “click”.

The crossover is removed by unscrewing the Philips head screws and removing the cables from the drivers.
