Break-in period
The speaker driver used in Sub 1000 F loudspeakers is a complex mechanical component which requires a certain time to adapt in order to operate at its best and to become acclimatised to the temperature and humidity of the listening environment. This break-in period varies depending on the conditions in question and may take several weeks. To reduce this break-in period, we recommend operating your subwoofer for about 20 consecutive hours. Once the speaker driver’s characteristics have totally stabilised, you will be able to enjoy the full capabilities of your subwoofer.
Specifications:
12″ (30cm) subwoofer with Flax cone: The speaker driver of this subwoofer is equipped with a sandwich technology Flax cone. Flax is an eco-textile with astounding structural properties: it is light, stiff and has excellent damping. Focal has developed a new 320 g/m2 Flax cone to ensure high rigidity but also high excursion.
Connections
Using the “low-level” RCA inputs
When a 2-channel amplifier with pre-out line outputs are used, the subwoofer should always be connected to the stereo RCA inputs “Left/Right LINE INPUTS” (fig. A).
Using the LFE input
When a multi-channel audio/video amplifier is used, the subwoofer’s single LFE input should be connected to the audio/video amplifier’s “Subwoofer” output if there is one (fig. B).
Positioning the subwoofer in the listening room
Contrary to loudspeakers, which have to be placed at a sufficient distance from the walls and corners of the listening room, we recommend positioning the subwoofer in a corner (fig. C,D).
If the subwoofer is positioned against only one wall or far away from the walls, the very long wavelengths of the low frequencies will cause the random excitation of room resonances. The frequency response will not be linear and the quality of the bass will be seriously affected (lack of depth, tinny sound, poorly defined and/or poorly held bass, difficult or impossible overlap crossover with other loudspeakers).
By placing the subwoofer 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 arrangement will also make it possible to boost the bass level by + 6 dB (fig. E).
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 towards the front of the room.
As the frequency ranges involved are in principle omnidirectional, the bass is not affected by objects or furniture placed between the subwoofer and the listening point.
Switching the subwoofer on/off
Automatic power-on / standby
This subwoofer is equipped with an automatic audio signal detection system. When switched to “Auto”, the subwoofer will turn on as soon as an audio signal input is detected. When switched to “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 3 minutes, the detection system will automatically put the subwoofer into stand-by.
If the subwoofer is going to be unused for several days or more, it is recommended to set the “POWER” switch to “Off”. In case of lightning, disconnect the power cable from the mains.
Quick set-up guide
- Plug subwoofer’s power cable into the mains.
- Connect the subwoofer to the amplifier according to one of the 3 methods mentioned previously.
- Set the “POWER” switch to “On”.
- Turn the “CROSSOVER” knob to half way (to approximately 100 Hz).
- Turn the “VOLUME” knob to half way.
Note: The “CROSSOVER” function will be disabled if the subwoofer is connected to the “LFE” input.
Fine-tuning
- Adjust the bass level according to the other loudspeakers used. This fine-tuning can be carried out by listening to music which varies as much as possible. One should be able to hear the bass without it being too overpowering.
- Select the desired phase inverter (0° or 180°). The correct setting is that which you think provides the most bass while being the most well-balanced.
- Fine-tune the cut-off frequency to around 100 Hz. The lower this setting, the more scale and depth the bass will have. The higher this setting, the punchier the sound will be. The correct setting is that which best provides all these characteristics.
- Adjust the volume if necessary.
- Fine-tuning should be carried out each time you change the position of the subwoofer.
Choosing the right cables
When your subwoofer is connected to an amplifier via the stereo line inputs or LFE input, use a shielded RCA/RCA cable of adequate length. In case of doubt, your dealer will be able to advise you on the solution which is best adapted to your needs.
Special precautions
The only maintenance required for the subwoofer is dusting with a dry cloth. If the subwoofer is dirty, we recommend simply cleaning it with a damp cloth.
Never use solvents, detergents, alcohol-based or corrosive products, scrapers or scourers to clean the loudspeaker surface. Keep the loudspeakers away from sources of heat.
