Introduction

Thank you for purchasing this B&W Active Subwoofer.

Since its foundation in 1966, the continuing philosophy of B&W has been the quest for perfect sound reproduction. Inspired by the company's founder, the late John Bowers, this quest has entailed not only high investment in audio technology and innovation but also an abiding appreciation of music and the demands of film sound to ensure that the technology is put to maximum effect.

This subwoofer has been designed for Home Theatre installations and to augment the bass performance of 'full range' speakers in 2-channel audio use. Adding the subwoofer to your system not only extends the bass to lower frequencies, it improves the midrange clarity by reducing the low-frequency demands on your existing speakers.

Please read through this manual fully before using the subwoofer. All sound installations require some planning and experimentation if you are to get the best out of the products used and this manual will guide you in this process.

As the subwoofer is connected to the electricity power supply, it is important that you familiarise yourself with the safety instructions and heed all warnings.

Keep this manual in a safe place for future reference.

B&W loudspeakers are distributed to over 60 countries worldwide and we maintain an international network of carefully chosen and dedicated distributors. If you have a problem, which your dealer cannot resolve, our distributors will be more than willing to assist you.

Unpacking (figure 1)

The easiest way to unpack the subwoofer and avoid damage is as follows:

• Open the carton flaps right back and invert the carton and contents.
• Lift the carton away from the product.

We recommend that you retain the packaging for future use.

In addition to this manual, the carton should contain:

What the subwoofer does

Application: Home Theatre

The primary function of the subwoofer is to reproduce signals from the Low Frequency Effects (LFE) channel. In addition, the processor may be configured to divert the low bass portion of some or all of the other channels and add it to the LFE information by configuring those speakers to 'small' in the processor set-up procedure.

Application: 2-channel audio

The subwoofer is used to extend the bass response beyond that provided by the satellite speakers. In most cases, best results are obtained if the satellite speakers are run full range as normal directly from the power amplifier. The subwoofer low-pass filter is then set so that its output rises as that of the satellite speakers falls naturally. However, if the satellite speakers are very small, the system output level may be limited by overloading their bass drivers. If this is the case, better results may be obtained by using the high-pass filters in the subwoofer to limit the bass energy fed to the satellite speakers.

Positioning the subwoofer

Because the subwoofer produces only low-frequency sounds, positioning is less critical in some respects compared to full-range speakers. Directional information is much less precise and you have more choice where to place the speakers to good effect. This said, best results are obtained if the subwoofer is placed between the left and right speakers or in the vicinity of one of them. If you use two subwoofer, it is best to put one near the left and one near the right speaker.

Placing the subwoofer behind the listeners, even in surround sound installations, generally gives inferior imaging, but may be an acceptable compromise if domestic considerations dictate.

As with all speakers, the proximity of room boundaries affects the sound. Bass is generally increased as more surfaces come into close proximity with the speakers. Unlike full-range speakers, however, you can always restore the correct overall system balance by adjusting the volume level of the subwoofer. The more boost you get from the room, the less hard the speaker has to work; but there is a down side. Corner positions often excite more low-frequency room resonances, making the bass more uneven with frequency. There is no substitute for experiment as all rooms behave differently, so try the subwoofer in a variety of positions before making a final decision. A piece of music with a bass line ascending or descending the musical scale is useful for assessing the smoothness of the bass response. Listen for exaggerated or quiet notes. Having a separate subwoofer does enable you to optimise for room resonances independently from sitting the satellite speakers for best imaging.

Electrical connections

Disconnect all sound system equipment from the power supply until the signal connections have been made and checked. This avoids the risk of damage whilst connections are made or broken.

The subwoofer will input and output both line-level signals via the RCA Phono sockets and speaker level signals via the binding posts located on the back panel.

Use the following guide to select the correct wiring method for your installation:

Using more than one subwoofer

Using more than one unit in a single installation can improve performance in the following ways:

• Maintain stereo separation to the lowest frequencies.
  Cope with larger listening rooms.

• Enable greater maximum sound output – often useful for effectively reproducing special effects in Home Theatre applications.

• Smooth out the effects of low-frequency room resonances.

If you are using two subwooers for 2-channel audio, stereo separation is improved if each channel has its own subwoofer, providing each one is placed close to the relevant satellite speaker. Only use the mono connection of figure 8 if you cannot place each subwoofer close to its satellite speaker.

Double-check the connections

ENSURE THAT THE VOLTAGE INDICATED ON THE AMPLIFIER PANEL MATCHES THAT OF THE POWER SUPPLY.

Before auditioning the sound quality of your new installation and fine-tuning it, double-check the connections. All too often, users complain that they cannot get a decent sound however they set the controls, only to discover something has been wrongly connected. Make sure that:

• The phasing is correct - there should be no positive to negative connections to the satellite speakers. If something is out of phase you may get a fuzzy sound with an imprecise and floating image, a lack of bass or a combination of the two.
• There are no left to right mix-ups – this can result, for example, in the orchestra being the wrong way round or, more dramatically, sounds on your Home Theatre going in the opposite direction to the action on the screen.

Switching on and off

We recommend that you switch the subwoofer on before any power amplifiers receiving signals from the subwoofer. Similarly, when switching off, switch the subwoofer off last.

THE MODE On/Auto switch (8) and indicator light (9) operate as follows:

On:

With the switch in this position, the amplifier remains permanently fully active, and the light glows green.

Auto:

On first switching on the subwoofer while set to Auto, the amplifier becomes fully active and the light (9) glows green. After a period of about 5 minutes without an input signal, the amplifier automatically reverts to standby mode, and the light glows red. When an input signal is detected, the amplifier automatically becomes fully active and the light glows green.

Setting the controls

There are 5 controls to consider:

The VOLUME control (10)
- The LOW-PASS FILTER frequency control (5)
The LOW-PASS FILTER switch (7)
The PHASE switch (6)

The EQ (equalisation) switch (4)

The optimum settings depend on the other equipment used with the subwoofer. If using more than one subwoofer, ensure the controls on each one are set the same.

Home theatre

The subwoofer is not a THX^ licensed component, but may be used with a THX^ controller if desired.

• Set the VOLUME control initially to the 9 o'clock position.
• Set the LOW-PASS FILTER switch to OUT.
• Set the EQ switch initially to position A.
• Set the PHASE switch initially to 0^ .
• The setting of the LOW-PASS FILTER frequency control is irrelevant.

See also the section "Fine tuning".

If you have a THX^ controller, ensure that the subwoofer function is enabled. When so configured it incorporates all the filtering and level setting required for the subwoofer in all modes. For level calibration, the internal test noise and channel level controls in the THX^ controller should be used. In all cases the levels should be set to obtain 75dB SPL (C-weighted) at the listening position from the controller's internal noise test signal.

With other processors, configure the front and surround speakers to "large" or "small" as appropriate before setting the levels. Use the internal noise test signal and volume controls of the processor to set the levels of all the speakers. Only change the VOLUME control on the subwoofer if there is not enough range in the processor to achieve the correct levels.

Inexpensive sound level meters are readily available from electronics stores and should be used to calibrate the levels. Refer to your processor manual for further details on how to set the levels.

2-channel audio

• Set the VOLUME control initially to the 9 o'clock position.
• Set the LOW-PASS FILTER switch to IN.
• Set the EQ switch initially to position A.
• Set the PHASE switch initially to 180^ .

If you are running the satellite speakers full range (figs 6, 7, 10, 11).

• Set the LOW-PASS FILTER frequency to the -6dB cut-off frequency of your satellite speakers.

Both -3dB and -6dB figures are to be found in the specification of each B&W speaker model. However, if the manufacturer of the satellite speakers does not quote a -6dB frequency, but only a -3dB frequency, the optimum setting for the LOW-PASS FILTER frequency control will be between 0.6 and 0.9 times the -3dB frequency, depending on the roll-off alignment. The more gradual the roll-off rate of the satellite speakers, the lower the frequency should be set.

If you are running the satellite speakers high-passed (figs 8, 9, 12, 13).

• Set the LOW-PASS FILTER frequency initially to 80Hz .

See also the section "Fine tuning".

Fine-tuning

Home theatre

With home theatre the subwoofer (LFE) signal is a separate channel rather than an extension of the signal to the satellite speakers. The LOW-PASS FILTER is switched out, because the processor provides all the filtering for any speakers set to "small". However, the position of the phase switch must still be assessed. Normally the phase will be set to 0^ , but if the subwoofer is positioned at a distance significantly different from the other speakers, or the power amplifier driving the other speakers happens to invert the signal, the 180^ position may be preferable. Listen with the switch in both positions and choose the one that gives the fullest sound. If there is little difference, leave the switch at 0^ .

Surround sound processors normally have a calibrated noise signal that can be used to set the relative levels of all the speakers, making the task somewhat more straightforward than for 2-channel audio. However, do not be afraid to alter the settings to your personal preference. It is all too easy to get carried away with the capabilities of the subwoofer, especially with some special low-frequency effects. Often a more realistic portrayal, and one more satisfying in the long term, is to be had by setting the subwoofer level lower than the standard calibration level.

2-channel audio

The optimum settings of the PHASE switch and the LOW-PASS FILTER frequency control are inter-related and also dependent on the low-frequency cut-off characteristic of the satellite speaker. However, the settings recommended above for the LOW-PASS FILTER frequency and PHASE have been chosen to add well to most bass alignments, whether closed-box or vented-box (reflex), with -dB frequencies within the adjustment range of the subwoofer.

If feeding the satellite speakers via the high-pass filter of the subwoofer, the frequency will need to be set lower than the initial value of 80Hz if the -3dB frequency of the satellite speakers is lower than 80Hz and higher if above.

Set the system up in the preferred position and play some programme with a steady bass content.

Using the initial settings guide, first check the setting of the PHASE switch. Choose the position that gives the fullest sound. Normally the recommended position will be optimum, but may not be in certain circumstances, such as if you are using line level connections and the power amplifiers feeding the satellite speakers invert the signal, or if the subwoofoers are not placed close to the satellite speakers.

Next, set the loudness of the subwoofer relative to the satellite systems to your liking. Use a wide variety of programme material to get an average setting. One that sounds impressive on one piece may sound overpowering on another. Listen at realistic levels as the perception of balance varies with sound level.

Finally, adjust the LOW-PASS FILTER frequency to give the smoothest transition between the subwoofer and satellite speakers. This is probably the most difficult to optimise.

All applications

The EQ switch alters the bass roll-off alignment. The bass you hear is a combination of the subwoofer plus the effects of the room and you should choose the position that best complements your room and the position of the subwoofer. Position A gives a drier alignment, more suited to placing the subwoofer in a corner or compensating a boomy room. Position B is more suited to a dry room acoustic and use away from a corner.

If you get problems with uneven bass - if certain bass notes are exaggerated more than others - then you probably have a room interface problem and it is worth experimenting with the placement of the subwoofer. What may seem like small changes in position - 15cm (6in) or so - can have a profound effect on the sound. Try raising the subwoofer clear of the floor as well as lateral movement. The use of multiple subwoofer can smooth the effects of room resonances, as each subwoofer will tend to excite resonances at different frequencies. If you alter the relative distances from the subwoofer(s) and satellite speakers to the listeners appreciably, reassess the phase switch setting. You should also check the level setting of the subwoofer (using either the processor output levels or the volume control on the subwoofer amplifier as appropriate), but only after setting the phase correctly.

When using more than one subwoofer, ensure that each one has its LOW-PASS FILTER frequency and PHASE set the same way.

Taking care of the subwoofer

The cabinet of the subwoofer may be cleaned by dusting with a dry cloth. If you wish to use an aerosol cleaning spray, do not spray directly on the cabinet; spray onto the cloth. Remove the grille first so that the cloth does not become stained, but be careful not to disturb the drive unit. The grille itself may be cleaned using a soft brush.

Do not use the subwoofer as a table. When in use, objects left on top of the subwoofer are liable to rattle. In particular, avoid the risk of liquids being spilled (eg from drinks or vases of flowers).

If the system is taken out of use for a long period, disconnect the subwoofer from the power supply.
