At B&W, we have always followed John Bowers' original philosophy of combining the art and science of acoustic design to create simply a better product, the objective always being to get the maximum amount of enjoyment and fulfilment from listening to music or watching movies. The original Nautilus 800 Series contained a raft of new technologies that propelled it to being probably the best selling high-end speaker range in the world. Since then, our team of research and development engineers have been striving to improve performance still further. Here is a short summary of what you will find new to this Series. Bass cones throughout now feature a sandwich construction of carbon fibre skins bonded to a Rohacell foam core. Rigid diaphragms are best for reproducing bass frequencies and this new construction allows us to thicken the cone section, without suffering increased mass. The extra thickness makes the cone a more effective barrier to any residual sound generated inside the cabinet, giving tremendous dynamics and timing to the bass, with the secondary effect of cleaning up the midrange. The FST midrange drive unit receives a new chassis ­ stronger, yet maintaining the maximum open area behind the diaphragm to minimise reflective obstruction and allow the free flow of air. The response of all B&W tweeters extends well into the ultrasonic region ­ important to realise the potential of SACD and DVD-A recordings. Now, the top models in the Series feature diamond dome tweeters. They're difficult and expensive to manufacture, but they take the response all the way to 80kHz in a smooth manner, superior to most socalled supertweeters. Crossover design ­ getting the signal to the drivers with the minimum of degradation and blending them seamlessly together ­ has long been regarded as something of a black art. For this Series, our engineers have taken a sideways look at some of the traditionally held views of filter design and bent the rules a little. The result is imaging with unsurpassed perspective and stability. These are speakers of the highest calibre and it's worth taking care with the set up of your system, so please take time to study this manual. Further information can be found in the FAQ and Technology sections of our web site www.bowerswilkins.com.

How to use the manual This manual covers all the passive speakers in the 800 Series. Even if some of the information does not immediately concern you, having it all in one place will help you in the choice of extra models you may require to expand your system at a later date. Each of the sections carries an identification number and you will be guided to the relevant sections by navigation instructions. marked with an f arrow. Some text, applicable to only certain models, is indicated by a vertical line to the left.

The following dedicated centre speakers are magnetically shielded because their application requires them to be placed right next to the screen: HTM1D HTM2D HTM3S HTM4S All other speakers in the Series should be placed at least 0.5m (20-in) from such screens. Some television brands are particularly sensitive to magnetic fields and may require extra spacing. Plasma and LCD screens are not affected and front projectors are usually well away from the speakers anyway. Application Front left and right Front centre Surround 2.1 f Go to 2.1 2.2 2.3 FRONT LEFT AND RIGHT If you're only interested in audio and not movies, space the speakers apart approximately the same distance as you sit from them. This means that the included angle is about 60º. This applies whether or not you are using a centre speaker. Apart from the dedicated on-wall model SCMS, the balance of the speaker is more natural if the speakers are at least 0.5, (20-in) from the rear wall. This also helps to improve the impression of perspective. (figure 2) If you are only concerned with 2-channel audio, having the speakers further apart can lead to what is known as the hole-inthe-middle effect, where it's difficult to generate a stable phantom central image. If you have a centre speaker, you can space the left and right speakers further apart. All that happens is that the image widens. It's just like being closer to the performance. If you have to space the speakers further apart because of domestic constraints, the central image can often be improved if you toe the speakers in towards the centre of the listening area. This can also help the perception of the central image for any listeners sitting away from the centre line of the installation. (figure 3) Different accessories are packed according to model. Use the chart of figure 1 to check the contents for your particular model. Contact your dealer if there are any missing items. 1 If you are also using the speakers for movies, you should try to match the audio image to the size of the screen. That generally means that the speakers should be closer together. A good starting point is to put the speakers about 0.5m (20-in) from the edges of the screen. (figure 4) Bookshelf or on-wall speakers should be placed at a height that brings the tweeters approximately to ear level. In the vertical plane, the dispersion narrows in the crossover region between the midrange and tweeter drive units, when both units are working together. To preserve the optimum sound balance, try to keep within ±5º of this. Floor-standing speakers have the angle of their optimum listening window adjusted for the height of the speakers and the typical range of ear height of seated listeners. f Go to section 3. 2.2 FRONT CENTRE Most films are originally balanced for cinemas, where a large number of speakers spread around the auditorium are used to create the surround sound field. In that case there are more surround speakers than there are discrete channels of information and a less precise image is created that gives an allenveloping effect. Dipoles and similar diffuse speakers are better at recreating this type of sound field in the home, but using fewer speakers to do it. Image positioning with these types of speaker is never as precise as it can be with monopoles. However, they do have the advantage of making it easier to balance the system for a larger listening area. You may well receive conflicting advice from different sources on the best type of surround speaker to use. The truth is that there is no one perfect solution for all situations and the final choice for any given application will be influenced by several criteria, some of which may have a degree of conflict. DS8S only Within the 800 series, the DS8S is the only speaker to offer dipole operation. In fact, this specialist surround speaker has the advantage of offering a choice of both monopole and dipole operation, either via a switch located on the front baffle, behind the removable grille, or remotely, using a 12V trigger from the surround processor. You may therefore choose whichever type of operation best suits the conditions of the listening room, the size of audience and the type of programme being played. Indeed, you may even change the characteristic for different types of programme and, as the total energy into the room is the same in both modes, no recalibration of the installation is necessary when switching between them. In monopole mode, only the two drive units on the front face operate. In dipole mode, the front tweeter is disconnected; the side firing drivers are brought into operation and the crossover frequency to the bass unit is lowered. The drive units on opposing sides are connected out of phase with one another, which creates a wedgeshaped null zone, approximately 60º wide, at right angles to the wall. If the listeners sit within this zone, they become less aware of the location of the speakers and hear more reflected sound; hence the diffuse nature of the sound field. Use the bottom switch on the front baffle when selecting between monopole and dipole modes. In the · position, the speaker defaults to monopole. (figure 8) However, if a 12V signal is applied to the trigger input, internal relays switch to dipole mode. In the ·· position, the speaker is always in dipole mode, whatever the trigger signal. (figure 9) Set the direction of the positive and negative dipole lobes using the centre toggle switch marked >< on the front baffle. The stem of the switch points in the direction of the positive lobe. For the smoothest panning of sounds between all the speakers in the installation, side speakers for all applications and rear speakers for 6.1 and 7.1 applications should have the polarity of the lobes set according to figure 10. Application 5.1 channel surround 6.1 and 7.1 channel side 6.1 channel rear 7.1 channel rear 2.4 f Go to 2.4 2.5 2.6 2.7 If you have an acoustically transparent screen, place the speaker behind the centre of the screen. Angle it towards the listeners if the tweeter is more than 5º from ear height. (figure 5) If you have a normal screen, place the speaker immediately above or below the screen, whichever is nearest ear height. Angle it towards the listeners if the tweeter is more than 5º from ear height. A stand with tilt adjustment is available for the HTM2D, HTM2S and HTM4S. Consult your dealer for details. (figure 6) If you are just listening to audio, place the speakers centrally and mount bookshelf or wall mount speakers with the tweeters at ear height. (figure 7) f Go to section 3. 2.3 SURROUND 5.1 CHANNEL SURROUND DS8S only If you are using the DS8S in dipole mode only, place the speakers on the side walls approximately 60cm (2 ft) above ear height and in line with the centre of the listening area. (figure 11) If you are using the DS8S and switching between dipole and monopole modes for different applications, place the speakers on the side walls approximately 60cm (2 ft) above ear height and slightly behind the centre of the listening area, keeping the listeners within the 60º wide null zone. (figure 12) All models except DS8S Place the speakers approximately 120º round from front centre. The shape of the room will dictate whether they are placed on a side or rear wall. (figure 13) f Go to section 2.8 2.5 6.1 AND 7.1 CHANNEL SIDE Surround speakers generally fall into two main types ­ those that one might describe as 'normal' speakers ­ socalled monopoles, where the sound comes from a set of drive units mounted on the front of the enclosure ­ and those that give a more diffuse sound field, such as dipoles. Each type has its advantages. Most multi-channel music is recorded with home entertainment in mind and is monitored using monopole surround speakers, whatever the multi-channel recording format. This enables better location of side and rear images, although the formation of such images is never quite as precise as it is between the front speakers. ...
