The lightning flash represented by the arrow symbol in an equilateral triangle is intended to alert users to the presence of the high voltage within the device which could cause an electric shock.

| Caution: To avoid any risk of electric shock, do not dismantle the top (or the rear) of this device. None of the components are to be replaced by the user. For any maintenance or repairs, please contact a qualified professional.|

The exclamation mark represented in an equilateral triangle is intended to alert users to the existence of important instructions in the user manual relating to the use and maintenance of the device.

  1. Read these instructions.

  2. Keep these instructions.

  3. Take the warnings into consideration

  4. Follow all the instructions.

  5. Do not use this device around water.

  6. Only clean with a dry cloth.

  7. Do not obstruct vents. Install the device following the instructions provided by the manufacturer.

  8. Keep the loudspeakers away from sources of heat, such as radiators, stoves, heat register or any other devices which give off heat (including amplifiers).

  9. Comply with power cord safety instructions. The power supply cord has a plug with two pins, one of which is slightly wider than the other. A grounded power supply cord has two pins and an aperture for the socket’s projecting earth pin. The wider of the two pins and the aperture are there for your safety. If the power cord plug doesn’t fit your power socket, contact an electrician and replace the obsolete power socket.

  10. Make sure the power cable can’t be walked upon, squashed or pinched. Pay close attention to the power plug and the connection of the cord to the device.

  11. Only use accessories recommended by the manufacturer.

  12. Only use fixing devices, stands, tripods, supports or tables recommended by the manufacturer or those supplied with the product. If using a trolley or cart, pay particular attention when moving the equipment to avoid any risk of damage or injury.

  13. Disconnect the device in the event of lightening or when the device won’t be used for long periods of time.

  14. All maintenance must be carried out by a qualified professional. Maintenance is necessary if any damage has been caused to the device, such as a damaged power cord or plug, damage due to liquid spilt on the device or objects inserted into the device, exposure to rain or humidity, a malfunction or physical damage.

  15. Do not use accessories not recommended by the manufacturer to prevent any risk of damage or injury.

  16. This product must only be connected to the type of power supply indicated on the device. In case of doubt about your electric installation, contact the retailer of the product or your electricity provider. For devices intended for using with batteries or other power sources, refer to the user manual.

  17. Never overload your power sockets, extension cord or multi-plugs. This may lead to fire or electric shock.

  18. Never insert an object into the vents on the device. It may come into contact with high-voltage components or cause a short circuit which may lead to fire or electric shock. Never get liquid on the device.

  19. Never try to repair this device yourself; opening the device may expose you to high-voltages and other risks. For any maintenance or repairs, contact a qualified professional.

  20. When it’s necessary to replace components, make sure the technician uses the components specified by the manufacturer or ones which have exactly the same characteristics as the original. Components which aren’t compliant may cause a fire, an electric shock or other accidents.

  21. After any repairs or an intervention on the device, ask the technician to test the equipment in order to check that the product works correctly and is safe.

  22. The device must not be mounted to a wall or ceiling unless intended by the manufacturer.

  23. The power cable at the back of the subwoofer enables the equipment to be disconnected from the power supply. The plug socket must always be accessible.

  24. Never expose the product to drops or splashes of water.

  25. Do not use this device in tropical climates.

  26. Do not use this device at altitudes of more than 2,000m.

A – Specifications

8″ (21cm) subwoofer: Polyflex cone.
Class D amplifier: for very high power and high-quality sound.
Phase inverter: for optimising the phase of the subwoofer and loudspeakers.
Timed automatic power-on/stand-by: automatically turns the amplifier on and off.
Smooth break-up protection: prevents saturation.
Low-level stereo inputs: RCA inputs.
LFE input on RCA left: direct mono input to connect to the “subwoofer” output of the Home Cinema amplifiers.
MDF cabinet: a rigid cabinet without resonance.
Profiled port: powerful bass without distortion.

B – Connections

On low-level RCA inputs:
When using a 2-channel amplifier with “Pre-out” line outputs, Cub Evo should be connected to the RCA stereo inputs “Line inputs Right (R)/Left (L)” (fig. A).

On LFE input:
When a multi-channel audio/video amplifier is used, Cub Evo’s single LFE input should be connected to the audio/video amplifier’s “subwoofer” output (fig. B).

C – Switching on/off

Cub Evo features a timed automatic power-on/stand-by function with an automatic audio signal detection system. When the “Power” switch is on “Auto”, the subwoofer will turn on as soon as an audio signal input is detected. When switched to “Power On”, the audio signal detection system is disabled and the subwoofer will stay on permanently.

On the other hand, when no audio signal is detected for approximately 20 minutes, the detection system will automatically switch the subwoofer into stand-by mode.

If the subwoofer is going to be left unused for several days, it is recommended to set the “Power” switch to “Off”.

D – Positioning

Contrary to loudspeakers, which have to be placed at a sufficient distance away from the walls and corners of the listening room, we recommend positioning Cub Evo subwoofer in a corner.

By placing Cub Evo in a corner, the room resonances will be excited in a more linear and predictable way. Not only will bass perception be optimal, but this disposition will also make it possible to boost the bass level by 6dB. If for practical reasons you aren’t able to place the subwoofer in a corner, experiment positioning the subwoofer in different places within the room until you find the best compromise.

Generally speaking, it is better to place the subwoofer in front of the listening position (fig. C). It isn’t recommended to place it at the back of the room.

As the frequency ranges involved are omnidirectional, in principle the bass is not affected by objects or furniture placed between the subwoofer and the listening point (fig. D et E).



E – Break-in period

The woofer used in Cub Evo is a complex mechanical component which requires a break-in period in order to operate at its best and to become acclimatised to the temperature and humidity of your environment. The length of time this takes can vary depending on the conditions and may extend over several weeks. To reduce this break-in period, we recommend operating your subwoofer for about 20 consecutive hours at medium volume, with music which is rich in bass. Once the loudspeakers’ characteristics have totally stabilised, you will be able to enjoy the full potential of your active subwoofer.

F – Conditions of warranty

Please contact your Focal dealer if you encounter any problems. The warranty in France for any Focal product is valid for 2 years from the date of purchase, and rights are non-transferable in the case of resale. In the case of defective equipment, the equipment must be shipped at your expense in its original packaging to the dealer who will test the equipment in order to determine the nature of the fault. If the product is still under warranty, the product will be returned to you or replaced, “shipping pre-paid”. If the product is no longer under warranty, you will be given an estimate for the repairs. The warranty does not cover damage resulting from improper use or incorrect wiring (e.g. burnt out voice coil, etc.) Outside of France, Focal products are covered by a warranty whose conditions are determined locally by the official Focal retailer in each country, in compliance with the laws in force in the respective geographical area.

G – Maintenance

Only clean Cub Evo with a dry microfibre cloth. If Cub Evo is dirty, we recommend simply cleaning it with a damp microfibre cloth.
Never use solvents, detergents, alcohol-based or corrosive products, scrapers or scourers to clean the surface of Cub Evo. Only wipe delicately and never press down hard.
