Connecting the Subwoofer
Option 1: Stereo Mode 8 ohm
- Connect the positive (+) terminals from each amplifier output to the red terminals on the subwoofer.
- Connect the negative (-) terminals from each amplifier output to the black input terminals on the C8S.
- Connect the subwoofer output terminals (L red (+) and L black (-)) to the respective inputs on your left speaker.
- Repeat for the right speaker using the R red (+) and R black (-) terminals.
- Ensure correct polarity to avoid phase issues with top-boxes.
Option 2: Dual Mono Sum 4 ohm
- Connect the positive (+) terminals from the amplifier output to the red terminals on the subwoofer.
- Connect the negative (-) terminals from the amplifier output to the black input terminals on the C8S.
- Establish a parallel connection between the L and R inputs as shown in the diagram.
- Set the PowerZoneTM Connect amplifier output to Sum of Left and Right in Output Routing.
Option 3: Dual Mono Sum 16 ohm
- Connect the positive (+) terminals to the L red terminal and negative (-) to the R black terminal.
- Establish a serial connection between the L and R inputs as illustrated in the diagram.
Frequently Asked Questions (FAQ)
-
Q: Can I use this subwoofer with any amplifier?
- A: While it can be used with various amplifiers, we recommend using our PowerZoneTM Connect series for optimal performance and integration with speaker presets.
-
Q: How do I ensure correct polarity during installation?
- A: When connecting cables, make sure to match positive and negative terminals accordingly to avoid phase issues with top-boxes.

Installation Manual
Introduction
C8S is a compact and shallow on-wall subwoofer. The subwoofers face the wall and the sound is reflected out to the surroundings, allowing the subwoofer to blend discretely into any modern environment and offering full protection of the drivers.
The C8S features a powerful 8” subwoofer with dual voice coil and a passive radiator to extend the sub bass performance to below 34 Hz. The built-in crossover with heavy duty terminals allows the cables for the top-boxes to be connected directly from the C8S. A built in mounting system also works as feet, so the subwoofer can either be hung on the wall or placed on the floor. Or, the feet can be removed and it can be placed under a sofa or other furniture. Measuring only 16 cm deep – or 19 cm with wall mount, the C8S offers very loud output for its size with real sub bass extension.
C8S is available in black and white and is designed to be used together with the Ci loudspeaker series by Blaze Audio.
Included in the box
- One subwoofer
- Wall bracket
- Mounting template
- Safety letter
Installation
There are three distinct methods for connecting the subwoofer to the input terminals. We recommend utilizing our PowerZone™ Connect amplifier series, which is designed to seamlessly integrate with our downloadable speaker presets accessible at blaze-audio.com.
Option 1 : If you’re NOT using a PowerZone™ Connect amplifier, consider
using option 1.
Options 2 or 3 : If your loudspeakers and C8S bass module are linked to
our PowerZone™ Connect amplifier, options 2 or 3 can be effectively utilized.
Connecting the speaker cable.
There are two sets of speaker terminals. The left terminal is for left and
right input from the amplifier, while the right terminal serves as outputs for
top-boxes.
Option 1: Stereo Mode 8 ohm
- Connect the positive (+) terminals from each amplifier output to the red terminals on the subwoofer, and connect the negative (-) terminals from each amplifier output to the black input terminals on the C8S.
- Connect L red (+) from the subwoofer output terminal to the red (+) input on your left speaker, and L black (-) from the subwoofer output terminal to the black (-) terminal on your left speaker. Likewise, connect R red (+) on the subwoofer output terminal to the red (+) input on your right speaker, and R black (-) from the subwoofer output terminal to the black (-) terminal on your right speaker.
Note: When connecting, polarity shall NOT be reversed, as the reflected sound from the wall will be in phase with the top-boxes.
Option 2: Dual Mono Sum 4 ohm:
This configuration is ideal for use with our PowerZone™ Connect amplifier
series. The subwoofer’s dual voice coil bass unit allows for parallel
connection of the inputs, requiring only a single cable run to the subwoofer.
This low-impedance solution is particularly suitable when long cable runs are
not needed.
- Connect the positive (+) terminals from the amplifier output to the red terminals on the subwoofer, and connect the negative (-) terminals from the amplifier output to the black input terminals on the C8S.
- Establish a parallel connection between the L and R inputs as illustrated in the diagram.
Note: The output on the PowerZone™ Connect amplifier. shall be set to “Sum” of Left and Right in Output Routing
Option 3: Dual Mono Sum 16 ohm:
This configuration is ideal for use with our PowerZone™ Connect amplifier
series. The subwoofer’s dual voice coil allows for serial connection of the
inputs, requiring only a single cable run to the subwoofer. This 16 ohm
solution is advantageous when long cable runs are necessary.
- Connect the positive (+) terminals to the L red terminal, and the negative (-) to the R black terminal.
- Establish a serial connection between the L and R inputs as illustrated in the diagram
Note: The output on the PowerZone™ Connect amplifier shall be set to 100 V using two (2) outputs as shown in amplifier manual.
Positioning the cabinet.
C8S is designed to be mounted on the wall with the woofers facing inwards. It
is also possible to have it standing with the woofers facing down towards the
floor.
For installation on wall
- Mark screw holes for wall bracket using the provided template.
- Mount the included wall bracket to the wall with the included screws.
- After the speaker cables are mounted to the terminals, hang the C8S in the bracket.
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 C8S Subwoofer has a high minimum impedance, making them an easy load for
amplifiers. We recommend using Blaze Audio’s PowerZone™ Connect DSP-enabled
amplifiers with power ratings that exceed the subwoofers’ 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.
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, 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, 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:
| Cable size/load | 8 Ω | 4 Ω | 2 Ω |
|---|---|---|---|
| 2 sq mm. | 20 m / 65 ft. | 10 m /32 ft. | 5 m / 16 ft. |
| 2,5 sq mm. | 30 m / 100 ft. | 15 m /50 ft. | 7,5 m / 25ft. |
| 4 sq mm. | 60 m /200 ft. | 30 m /100 ft. | 15 m / 50 ft. |
