A litre en premier!

Thank you for purchasing the Cub^2 active subwoofer which has been designed to be used in a wide range of audio system applications, stereo or multichannel. It is ideally partnered with the matching Sib line satellite loudspeaker for a system that combines high performance sound with elegance and discretion.

In order to gain the maximum performance from this product it is essential that you read the following instructions thoroughly.

We advise you to keep this guide so that you can consult it when needed.

Specifications

21cm(11^ ) subwoofer: polypropylene cone.

BASH® 150Wrms amplifier: high-performance digital amplification technology for high-power and high quality sound.

Active crossover with adjustable crossing frequency: it allows to adjust with high accuracy the frequency range according to the performances and characteristics of the other used loudspeakers.

Phase selector: subwoofer/LOUD-speaker coupling optimization.

Auto on/standby system: the BASH^® amplifier automatically switches on or off (standby).

Soft clipping: avoids saturation.

High level stereo inputs: low level inputs on RCA and high level binding post terminals for a highly flexible system. LFE direct input: direct mono input to connect to the subwoofer output of home theatre amplifiers.

MDF manufactured enclosure: rigid cabinets free of internal resonances.

Profiled vent port: vigorous bass reproduction, no distortion effects.

Connections

"High level" inputs When using a standard two channels stereo amplifier, the Cub^2 must be connected through the "high level inputs". The two stereophonic loudspeakers will then have to be connected directly to the high level outputs of the subwoofer (fig. A). It is imperative to respect the connectors' polarity of both the loudspeaker and amplifier. The positive terminal "+" (red) must be connected to the corresponding amplifier's terminal (red) and the negative terminal "-" (black) to the negative terminal of the amplifier.

Low level inputs on RCA When using a two-channels amplifier with pre-out line outputs, the Cub^2 must be connected through RCA stereo inputs "line inputs Right/Left" (fig. B).

LFE input When using an audio/video multi-channel amplifier, the single LFE input of the Cub^2 should be connected to the mono "Subwoofer" output of the audio/video amplifier (fig. C). In that case, all controls of the Cub^2 will be off, except the volume control. Considering the fact that the audio/video amplifier already features all the necessary functions, this configuration is recommended for home theatre use only.

Positioning

Contrary to conventional hi-fidelity loudspeakers which have to be placed at a reasonable distance from the walls and the listening area corners, we advise you to place your Cub^2 subwoofer in a corner of the listening area (fig. D, E). If the subwoofer is placed against only one wall or too far from the walls, the very large wavelength of the bass delivered by the subwoofer will excite the resonance of the listening room in an unpredictable way. Frequency response linearity will then be damaged and therefore the sound rendition will be affected (lack of depth, "boomy sound", poor bass, difficult or impossible coupling with the other used loudspeakers).

If you put the Cub^2 in a corner, the resonant frequencies of the room will be more linear and predictable. In such a configuration, you will not only benefit from an optimum perception of the bass frequency range but the bass level will also be increased by 6dB (fig. F).

If a particular disposition of the room does not allow to place the subwoofer in a corner, we recommend you to try different configurations until you find the best possible disposition.

Generally, the subwoofer should be placed along the front wall of the listening room.

Because the bass frequency waves are omni-directional, the sound dispersion will not be affected if a piece of furniture or an object is placed between the subwoofer and the listening area.

Choice of cables

When the Cub^2 is connected to the amplifier through the "high level" inputs, it is recommended to use standard loudspeakers cables with 1.5mm^2 minimum section. When the Cub^2 is connected to the amplifier through stereo "line level" or LFE inputs, use a RCA/RCA shielded cable of the required length. In every case we advise you to ask your retailer. He will help you find the solution meeting your needs.

Settings

Autopower

The Cub^2 features an automatic audio signal detector.

When the "power" control is set on auto-mode, the subwoofer will automatically switch on as soon as an audio signal is detected. When set to "power on", the signal detector is disable and the subwoofer is continuously on.

Conversely, if no signal is detected during a period of about 3 minutes, the detector automatically set the subwoofer to standby mode.

If you expect not to use the subwoofer for a long period, it is recommended to set the power selector to "off".

In case of stormy weather, unplug the power cable.

Quick set-up

1 - Connect the subwoofer to the power grid (electrical outlet).
2 - Set the power selector to "on".
3 - Connect the subwoofer to the amplifier according to one of the three methods mentioned above.
4 - Set the "crossover" potentiometer to intermediate position (around 100Hz ).
5 - Set the "volume" potentiometer to intermediate position.

Please note that the crossover and phase functions are not available when the Cub^2 is connected through the "Line Inputs LFE".

Fine tune

1 - Adjust the bass level according to the other used loudspeakers. In order to find the appropriate settings, we advise you to use as many different music styles as possible. Bass must be present but not too heavy.
2 - Choose the phase selector mode (0^ or 180^) . The proper setting must make you feel that the bass level is higher and well balanced.
3 - Adjust the crossing frequency around 100Hz . The more you lower this frequency, the more the sound appears to be deep and sonorous. The higher the frequency is, the more you will feel a dynamic bass impact. The right settings are obtained when all these previously stated conditions are fulfilled.
4 - Re-adjust, if necessary, the volume control of the Cub^2
5 - The settings must be adjusted each time that the subwoofer is moved from its initial place.

Running-in period

The driver used in the Cub^2 is made up of complex mechanical elements and requires an adaptation period before it delivers the best of its performances. They must get adapted to the temperature and humidity conditions of their environment. This breaking-in period depends upon the encountered conditions and can last several weeks. In order to shorten this period, we advise you to let your subwoofer operate for about twenty hours at medium level, playing standard music programs, but with a large amount of bass. Once the components of the speaker are completely stabilized, it is possible to enjoy the true performances of your self powered subwoofer.

Magnetic disturbance

The Cub^2 generates a magnetic field that may interfere with other sensitive household appliances. It is strongly advised not to place the Cub^2 closer than 50cm ( 20'' ) to your TV screen (fig. H). Frame geometry as well as colours can be severely distorted by a magnetic field if the loudspeaker is placed to close to the cathode ray tube.

Generally, every sensitive elements (audio tapes, video tapes, magnetic data storages, projector and display devices etc.) should not be placed too close to non-shielded loudspeakers.
