Bowers & Wilkins CT SW15 [11/108] Limited warranty

The EQUILISATION switch alters the subwoofer bass

roll-off alignment appropriate to MOVIE or MUSIC

listening. The MOVIE position gives a “drier” alignment,

more suited to the demands of action movie low

frequency effects. The MUSIC position is suited to a

faster more accurate bass line. The 3.5mm

Equalisation input on the back panel is designed to

receive a 12V signal that will toggle the MOVIE/MUSIC

setting at the front panel. Set appropriately, the 12V

trigger output of a processor can automate ideal

performance of the subwoofer. If the front panel switch

is set for MOVIE, the 12V trigger will change it to

MUSIC. The reverse is also true. Care must be taken

in setup of the processor in order to take advantage of

this feature.

If you get problems with uneven bass – certain bass

notes are exaggerated more than others – then you

probably have a room interface problem and it is worth

experimenting with the location of the subwoofer.

What may seem like small changes in position – 15cm

(6in) or so – can have a profound effect on the sound.

The use of multiple subwoofers can smooth the

effects of room resonances, as each subwoofer will

tend to excite resonances at different frequencies. If

you appreciably alter the relative distances from the

subwoofer(s) and satellite speakers to the listening

position, re-assess the PHASE switch setting. You

should also check the volume 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.

Running-in Period

The performance of the speaker will change subtly

during the initial listening period. If the speaker has

been stored in a cold environment, the damping

compounds and suspension materials of the drive

units will take some time to recover their correct

mechanical properties. The drive unit suspensions will

also loosen up during the first hours of use. The time

taken for the speaker to achieve its intended

performance will vary depending on previous storage

conditions and how it is used. As a guide, allow up to

a week for the temperature effects to stabilise and

15 hours of average use for the mechanical parts to

attain their intended design characteristics.

However, longer run-in periods (as long as a month)

have been reported and there is evidence to suggest

that this has little to do with the speaker changing and

more to do with the listener getting used to the new

sound. This is especially so with highly revealing

speakers such as these where there may be a

significant increase in the amount of detail compared

with what the listener has previously been used to; the

sound may at first appear too “up front” and perhaps a

little hard. After an extended period of time the sound

will seem to mellow, but without losing clarity and detail.

Aftercare

The cabinet surfaces usually only require dusting. If

you wish to use an aerosol or other cleaner, remove

the grille first by gently pulling it away from the

cabinet. Spray aerosols onto the cleaning cloth, not

directly onto the product. Test a small area first, as

some cleaning products may damage some of the

surfaces. Avoid products that are abrasive, or contain

acid, alkali or anti-bacterial agents. Do not use

cleaning agents on the drive units. The grille fabric

may be cleaned with a normal clothes brush whilst the

grille is detached from the cabinet.

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 (e.g.

from drinks or vases of flowers).

If the system is taken out of use for a long period,

disconnect the subwoofer amplifier from the mains

supply.
