4 Self-adhesive rubber stand-offs

Speaker Installation

The speakers are best used mounted on rigid floor-

stands that locate the tweeters approximately at ear

level when seated. Shelf or wall bracket mounting is an

option but it provides less opportunity for optimising

the sound through adjustment of speaker position.

If the speakers are to be stood on a shelf or furniture

unit the adhesive pads supplied may be used.

The speakers can be mounted on walls using either

the "keyhole" aperture hardware already attached to

their back panels or by employing ball-joint style

speaker mounting brackets designed for 60mm

(2.36 in) mounting hole centres. If the keyhole

hardware is employed, the rubber pads supplied in the

accessory pack may be used to cushion the speakers

against the wall. Ball-joint style brackets allow the

speakers to be angled with respect to the wall. You

should ensure that the ball-joint brackets are capable

of supporting the weight of the speaker. Your dealer or

local B&W distributor will be able to advise you on the

selection of appropriate ball-joint brackets.

To attach a ball-joint style bracket to a 686 speaker,

remove the bracket hardware from the back panel of

the speaker and securely attach it via the keyhole

aperture to the ball component of the bracket. Re-

attach the bracket and ball assembly to the back

panel. Figure 2a illustrates this procedure.

To attach a ball-joint style bracket to a 685 speaker,

remove the bracket hardware from the back panel of

the speaker and secur

ely attach the ball joint plate

component in its place. Figure 2b illustrates this

procedure.

nce the ball joint component is attached to the

speaker, the assembly may be connected to the

ocket component attached to the wall. Ensure that

the Manufacturer’s instructions for attaching the

racket to the wall are followed correctly.

f either keyhole or ball-joint style solutions are used,

nsure that the wall fixings are sufficient to hold the

weight of the speakers. B&W can accept no liability for

ny failure of wall fixings.

Speaker Positioning

Adjustment of speaker position following initial

nstallation will probably further improve the sound

uality and is usually worthwhile.

In either stereo or home theatre installations try to

nsure that the immediate surroundings of each

speaker are similar in acoustic character. For example,

if one speaker is adjacent to bare walls while the other

is adjacent to soft furnishings and curtains, both the

overall sound quality and the stereo image are likely to

be compromised.

Conventional Stereo Systems

To begin with, the speakers should be positioned

between 1.5m (5 ft) and 3m (10 ft) apart at two

corners of an equilateral triangle completed by the

listening area at the third corner. The speakers should

be approximately 0.5m (20 in) away from the back

wall, and at least 0.5m (20 in) away from any side

walls. Figure 1a illustrates this arrangement.

Home Theatre Systems

If the speakers are to be used for the front channels in

a home theatre system they should be placed closer

together than for 2-channel audio because the

surround channels tend to widen the image.

Positioning the speakers within approximately 0.5m

(20 in) of the sides of the screen will also help keep

the sound image in scale with the visual image. The

speakers’ height should be somewhere between the

centre of the screen and the height of the centre

speaker. As with conventional stereo positioning, the

speakers should ideally be approximately 0.5m (20 in)

away from the back wall, and at least 0.5m (20 in)

away from any side walls.

If the speakers are to be used for the surround

channels in a home theatre system position them as

illustrated in Figures 1c to 1e according to the number

of channels. To achieve even coverage over an

extended listening ar

ea it is beneficial to raise the

speakers above ear height.

Stray Magnetic Fields

The speaker drive units cr

eate stray magnetic fields

that extend beyond the boundaries of the cabinet. We

ecommend you keep magnetically sensitive articles

(CRT television and computer screens, computer

discs, audio and video tapes, swipe cards and the

like) at least 0.5m (20 in) fr

om the speaker

. LCD and

plasma screens are not affected by magnetic fields.
