CARE AND MAINTENANCE

If you play the speakers with the grilles off exercise great care.
NEVER touch the drive units which are easily damaged.

The loudspeaker cabinets can be cleaned with a damp cloth or with
a spray furniture polish and a soft cloth. Apply the spray sparingly

SETTING UP TWO SUBWOOFERS

General notes

Site the subwoofers so that they enhance the system bass
response but do not cancel each other out.

! A well-sited pair of subwoofers for stereo applications

will be ade quately sited for Ho me Cine ma
applications.

! A second subwoofer raises the bass output level 6dB

when operating in Home Cinema but not in Stereo.

! Both subwoofers should be in line of sight to the

listening seat as both answer to one remote handset.

! When operating two subwoofers, do all setups and

operations on one handset When allocating presets
make sure that the same preset (e.g. Home Cinema on
preset 1) is allocated to each subwoofer.

Home Cinema:

! As AV Processors produce a common subwoofer

channel, considerations of Left and Right do not
apply, but with spaced subwoofers each helps to fill in
the troughs caused by in-room standing waves,
smoothing the bass and giving the sound greater
intensity, ‘air’ and depth.

! Set up the position of each subwoofer separately with

the other one switched off. After you have set both
subwoofers up, reduce the front panel volume level of
each subwoofer by 3 points. Complete the final
adjustment with both subwoofers switched on. You
may need to make some small adjustments to the
position of each sub for best results. We suggest you
enter this final setting as a Home Cinema preset.

Stereo:

! Each subwoofer should be located as near as possible

to its partnering loudspeaker. The smaller the main
speakers, the more necessary this becomes.

! It is it is easier to set up each subwoofer with a mono

source playing through one channel with the other
channel turned off.

! Complete the adjustment by ear using a mono source

with both channels and subwoofers operational. We
suggest you enter this setting as a Stereo preset.

areas with severe peaks at some frequencies and severe troughs at
others. These peaks and troughs are called ‘standing waves’ and if you
site loudspeakers in such areas the response will be highly non-linear.
With subwoofers this situation is exacerbated by the fact that it is easier
to treat high frequency irregularities by the use of drapes, soft
furnishings etc., but very hard to do the same at bass frequencies due to
the very long wavelengths - at 40 Hz the wavelength is almost 9 metres!

To help locate standing waves in your listening room, one idea is to sit in
the listening seat and recruit a friend with a deep voice to speak as he
moves around the area where you propose to site your subwoofer - you
will soon find out where not to site it! Where the voice sounds most
natural is a good place to start.

The low frequency response of the subwoofer and its blend with the main
loudspeakers is greatly affected by positioning. Although bass is
