It is not always necessary or desirable to point surround speakers directly at the listening area. Doing so can often attract undue attention to them, especially when your head is turned from looking directly to the front, so experiment before investing in special brackets. 5.1 systems (figure 4) Place the speakers approximately 120. round from front centre. This will determine whether they are placed on the side or rear wall. 6.1 systems with one rear speaker (figure 5) Place the side speakers in line with the centre of the listening area and one speaker centrally on the rear wall. 7.1 systems and 6.1 systems with two rear speakers (figure 6) Place the side speakers in line with the centre of the listening area. Place two speakers along the rear wall to make an angle of approximately 40. to the centre of the listening area. Connections (figure 7) All connections should be made with the equipment switched off. Ensure the positive terminal on the speaker (marked +) is connected to the positive output terminal of the amplifier and negative (marked –) to negative. 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 If the sound is too harsh, increase the amount of soft furnishing in the room (for example use heavier curtains), or reduce it if the sound is dull and lifeless. Test for flutter echoes by clapping your hands and listening for rapid repetitions. Reduce them by the use of irregular shaped surfaces such as bookshelves and large pieces of furniture. Mounting the speaker To the wall Use the wall plate supplied if you do not need to angle the speaker. (figure 8) At each end of the terminal tray at the back of the speaker is a dovetail feature that slides into the wall plate. Use the template provided to mark the position of the fixing screws for the wall plate. The overall height and width of the template correspond to the size of the speaker and both the vertical and horizontal centre lines are marked. This allows you to align the speakers with the television screen and any other objects. Pierce through the screw position marks in the template to leave an indent in the wall. Hold the wall plate against the wall, aligned with the screw marks and trace round the inside of the oval hole, which is used for cable entry. With solid walls, chase out a channel for the speaker cable, ending where you have marked the oval hole. In cavity walls, simply drill through the plasterboard and feed the cable through into the cavity. Screw the wall plate to the wall using a spirit level to accurately set it square. Small angular deviations may not be noticeable to the eye when looking at the small plate, but become more obvious with the speaker itself. Connect the cable before sliding the speaker onto the wall plate. If you need to angle the speakers, two threaded inserts are provided to allow the use of an auxiliary mounting bracket. We recommend the OmniMount® type 10.0 wall or ceiling for the FPM4 and FPM5 and type 20.0 wall or ceiling for the FPM6. These allow sideways angling and a downward tilt of up to 10. when the bracket is mounted above the terminals and the bottom of the speaker touches the wall. For the FPM2, the Omnimount® type 10.0 wall or ceiling allows extensive adjustment of angle. Follow the instructions provided with the bracket and fix the mounting plate to the back of the speaker using the two M6 screws provided with the speaker. (figure 9) 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. On a shelf or table (FPM2 only) A rear support leg is provided to enable the speaker to stand upright on a flat surface. With the strengthening rib pointing away from the enclosure, attach the leg to the two threaded inserts in the back of the speaker, using the screws provided. Stick the two clear rubber pads to the underside of the grille frame. (figure 10) To the optional table stand or floor stand Mounting instructions are provided with the stands. The table stand allows the speaker to be mounted in either vertical or horizontal orientation. The floor stand allows only vertical orientation. The FPM2 is not suitable for fixing to either the table stand or the floor stand. Running-in period The performance of the speaker will change subtly during the initial listening period. If the speaker has been stored in a cold environment, the damping compounds and suspension materials of the drive units will take some time to recover their correct mechanical properties. The drive unit suspensions will also loosen up during the first hours of use. The time taken for the speaker to achieve its intended performa...
