User manual B&W 801D

[. . . ] Dear customer, Thank you for choosing Bowers & Wilkins. 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. [. . . ] The speakers may be fixed to a wall or ceiling using screws in the range 5mm to 6mm diameter (No. On the back of the cabinet are three wall plates. The screw head should be inserted into the round part of the aperture and slid fully along one of the slots. The slots are sprung loaded to prevent the speaker being readily knocked out of position. The screw length should be chosen to give a minimum of 25mm (1 in) engaged thread. (figure 28) Ensure, especially when fixing to drywall panels, that the screw length and wall plug security are sufficient to hold the weight of the speaker. B&W can accept no liability for any failure of wall or ceiling fixings. Use the template provided to mark the screw positions. the outside dimensions of the template correspond to the rear of the cabinet. Stick 4 of the clear self-adhesive rubber pads to the rear panel of each speaker, one close to each corner. These stop the speaker vibrating against the surface and help keep it in position. (figure 30) Adjust the protrusion of the screws such that the rubber pads are a friction slide on the surface when the wall plates are hooked over the screw heads. (figure 31) Always check and ensure that: · All the screws slide right to the ends of the slots in the wall plates. Screw protrusion is adjusted so that the rubber pads provide enough friction to prevent the speakers sliding out of position. The speaker is designed to be fixed to a wall and is supplied with a bracket that allows adjustment of both horizontal and vertical angles. (figure 29) The bracket should be fixed to the wall using screws in the range 5mm to 6mm diameter (No. The screw length should be chosen to give a minimum of 25mm (1 in) engaged thread. (figure 28) Hold the template provided against the wall in the desired position and use a spirit level to line it up properly. the outside dimensions of the template correspond to the rear of the cabinet. Note especially that the centre of the wall plate does not coincide with the centre line of the speaker. mark the fixing holes on the wall and drill and plug the wall. Ensure that the screw length and wall plug security are sufficient to hold the weight of the speaker. [. . . ] Colour differences may be rectified by exposing all the veneer surfaces equally and evenly to sunlight until the colour is uniform. This process can take several days or even weeks, but may be accelerated by careful use of an ultra-violet lamp. 800D , 801D , 802D , HTM1D only To replace the midrange grille , locate the central peg in the hole at the tip of the plastic centre plug fitted to the drive unit. Push the centre of the grille firmly, but do not force a misaligned peg as damage may result. [. . . ]
