Welcome to B&W.
This product has been designed and manufactured to the highest quality standards. However, if something does go wrong with this product, B&W Loudspeakers and its national distributors warrant free of charge labour (exclusion may apply) and replacement parts in any country served by an official B&W distributor.
This limited warranty is valid for a period of five years from the date of purchase or two years for electronics including amplified loudspeakers.
Terms and Conditions
1The warranty is limited to the repair of the equipment. Neither transportation, nor any other costs, nor any risk for removal, transportation and installation of products is covered by this warranty.
2This warranty is only valid for the original owner. It is not transferable.
3This warranty will not be applicable in cases other than defects in materials and/or workmanship at the time of purchase and will not be applicable:
a.for damages caused by incorrect installation, connection or packing,
b.for damages caused by any use other than correct use described in the user manual, negligence, modifications, or use of parts that are not made or authorised by B&W,
c.for damages caused by faulty or unsuitable ancillary equipment,
d.for damages caused by accidents, lightning, water, fire heat, war, public disturbances or any other cause beyond the reasonable control of B&W and its appointed distributors,
e.for products whose serial number has been altered, deleted, removed or made illegible,
f.if repairs or modifications have been executed by an unauthorised person.
4This guarantee complements any national/regional law obligations of dealers or national distributors and does not affect your statutory rights as a customer.
How to claim repairs under warranty
Should service be required, please follow the following procedure:
1If the equipment is being used in the country of purchase, you should contact the B&W authorised dealer from whom the equipment was purchased.
2If the equipment is being used outside the country of purchase, you should contact B&W national distributor in the country of residence who will advise
where the equipment can be serviced. You can call B&W in the UK or visit our web site to get the contact details of your local distributor.
To validate your warranty, you will need to produce this warranty booklet completed and stamped by your dealer on the date of purchase. Alternatively, you will need the original sales invoice or other proof of ownership and date of purchase.
Owner’s manual
Introduction
Thank you for choosing Bowers & Wilkins.
We are confident that you will enjoy many years of listening pleasure from your speakers, but please read this manual fully before installing them. It will help you optimise their performance.
B&W maintains a network of dedicated distributors in over 60 countries who will be able to help you should you have any problems your dealer cannot resolve.
Unpacking (figure 1)
•After opening the top carton flaps, remove the accessories from the polystyrene tray.
•Fold the carton flaps right back and invert the carton and contents.
•Lift the carton clear of the contents, remove the upper polystyrene tray and retrieve the separate grille.
•Turn the speaker over again and remove the remaining packaging.
•Remove the protection cover from the tweeter and fit the grille if required, applying pressure over the position of the pegs.
We suggest you retain the packing for future use.
Positioning (figure 2)
Do not fit the spike feet until you have found the best position for your speakers.
As an initial guide:
•Position the speakers and the centre of the listening area approximately at the corners of an equilateral triangle.
•Keep the speakers at least 1.5m apart to maintain left-right separation.
•Keep the speaker baffles at least 0.5m clear of walls.
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.
Connections (figure 3)
All connections should be made with the equipment switched off.
There are 2 pairs of terminals at the back of the speaker which permit bi-wiring if desired. On delivery, the separate pairs are connected together with high-quality links for use with a single 2-core cable. For single cable connection, leave the links in place and use either pair of terminals on the speaker.
Ensure the positive terminal on the speaker (marked + and coloured red) is connected to the positive output terminal of the amplifier and negative (marked – and coloured black) to negative. Incorrect connection can result in poor imaging and loss of bass.
To bi-wire, remove the links by loosening the terminal caps and use a separate
2-core cable from the amplifier to each pair of terminals. This can improve the resolution of low-level detail. Observe the correct polarity as before. When bi-wiring, incorrect connection can also impair the frequency response.
The terminals accept 6mm (1/4-in) spades, bared wire ends or round pins up to 6mm diameter and 4mm banana plugs. When using spades, fit them under the sliding collar.
Important safety notice:
In certain countries, notably those in Europe, the use of 4mm banana plugs is considered a potential safety hazard, because they may be inserted into the holes of unshuttered mains supply sockets. In order to comply with European CENELEC safety regulations, the 4mm holes in the ends of the terminals are blocked by plastic pins. Do not remove the pins if you are using the product where these conditions apply.
Always screw the terminal caps down tightly to optimise the connection and prevent rattles.
Ask your dealer for advice when choosing cable. Keep the total impedance below the maximum recommended in the specification and use a low inductance cable to avoid attenuation of the highest frequencies.
Fine tuning
Before fine tuning, double check that all the connections in the installation are correct and secure.
Moving the speakers further from the walls will reduce the general level of bass. Space behind the speakers also helps to create an impression of depth. Conversely, moving the speakers closer to the walls will increase the level of bass.
If you want to reduce the bass level without moving the speakers further from the wall, fit the foam plugs in the port tubes
(figure 4).
If the bass is uneven with frequency it is usually due to the excitation of resonance modes in the room. Even small changes in the position of the speakers or the listeners
