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.
The specific stand or wall mount used will affect the sound quality of the speakers. The B&W
If the speakers are to be placed on a shelf or furniture unit, the adhesive pads supplied may be attached to the underside of the cabinet.
Speaker Positioning
Adjustment of speaker position following initial installation will probably further improve the sound quality and is usually worthwhile.
In either stereo or home theatre installations try to ensure 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 and 3m apart at two corners of an equilateral triangle completed by the listening area at the third corner. The speakers should be approximately 0.5m away from the back wall, and at
least 0.5m 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
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 area it is beneficial to raise the speakers above ear height.
Stray Magnetic Fields
The speaker drive units create stray magnetic fields that extend beyond the boundaries of the cabinet. We recommend you keep magnetically sensitive articles (television and computer screens, computer discs, audio and video tapes, swipe cards and the like) at least 0.5m from the speaker. LCD and plasma screens are not affected by magnetic fields.
Connections
All connections should be made with the equipment switched off.
There are 2 linked pairs of terminals on the back of the speaker. For conventional connection the terminal links should remain in place (as delivered) and just one pair of terminals connected to the amplifier. For
Ensure that positive terminals on the speaker (marked
+and coloured red) are connected to the positive output terminal on the amplifier and that negative terminals on the speaker (marked – and coloured black) are connected to the negative output terminal on the amplifier. Incorrect connection can result in poor imaging and loss of bass.
Ask your dealer for advice when selecting speaker cable. Keep its total impedance below the maximum recommended in the speaker specification and use a low inductance cable to avoid attenuation of high frequencies.
Fine Tuning
Before fine tuning, make sure that all the connections in the installation are correct and secure.
