User manual B&W CWM 650

[. . . ] The speakers may be mounted in either portrait or landscape orientation. Wherever possible, however, portrait orientation, with the drive units mounted one above the other, is to be preferred as it gives better horizontal dispersion and a more stable stereo image. If landscape orientation is used, orient the baffle so that the tweeters are towards the centre of the room. Do not mix portrait and landscape at left and right, as an imprecise stereo image will be created. [. . . ] In addition, loosely fill the whole section of the wall cavity with wadding. Fibreglass and mineral wool matting supplied for heat insulation are suitable, but not closed cell foam or expanded polystyrene. Check that there is no debris that may fall into the speaker (especially in ceiling mount situations). IMPORTANT: YOU SHOULD CHECK THAT THE MATERIALS YOU USE MEET THE LOCAL FIRE AND BUILDING REGULATIONS. UNPACKING (figure 1) · Fold the top carton flaps right back and invert the carton and contents. Check the contents: · 2x Baffle with drive units, crossover and foam · 2x Wall frame with swing out dogs · 2x Loudspeaker grille · 1x Alignment template · 1x Accessory pack containing: 8x Self-Tapping screws (for frame to PMK fixing) Not for CWMTM500 8x Machine screws (fixing baffles to wall frames) We suggest you retain the packaging for future use. Remove the grilles and baffles (Not for CWMTM500) from the wall frames and, to avoid damage, keep them in their plastic bags (and preferably in the carton) away from the work area until you are ready to fit them. FITTING THE WALL FRAME New Construction (figure 3) Fit the separately available pre-mount kit ­ (PMK500 for CWMTM500, PMK650 for CWMTM650, PMK800 for CWMTM800) to the studding before the drywall panels are fitted, following the instructions supplied with the kit. The drywall panels should be fitted up to the pre-mount frame and plastered over. Screw, but do not tighten, 4 of the screws provided through the slots in the wall frame into the pilot holes in the pre-mount frame. (The CWMTM500 does not attach to the premount frame directly, but uses the clamping dogs described below). Existing Construction (figure 4) Push out the slots in the template provided. Mark along the inside edges of the slots and cut out the aperture neatly. Position the frame in the wall and screw in the 6 (or 4 for CWMTM500, where the baffle/frame is fitted as one assembly) screws visible from the front of the frame. Ensure that they have located properly and loosely tighten the screws. POSITIONING ­ NEW CONSTRUCTION VERSUS RETROFIT Check that there is no conflict with other in-wall installations (pipe work, air conditioning, powercabling etc. ). In existing construction, use a stud-finding tool to map the wall construction accurately and a pipe detector to scan the proposed installation position. Avoid installing the speakers in the same cavity of the wall as flimsy ducting, which may be induced to rattle. 1 Existing construction Method 2 Using the pre-mount frame in retrofit situations requires that the aperture is cut fairly accurately. Use the template provided to mark out the correct size aperture, having regard to how the wall frame is to be lined up with any features such as door frames, and cut out the aperture neatly. Feed the pre-mount frame through the aperture and pull it forward so that it sits flat on the rear of the drywall and the inner part of the frame protrudes through the aperture. Screw, but do not tighten, 4 of the screws provided through the slots in the wall frame into the pilot holes in the pre-mount frame. A certain amount of flexing of the wall frame is allowed to take up unevenness in the wall surface, but do not over tighten the screws as excessive distortion of the frame may impede the fitting of the baffle. Installing an IR Sensor A pilot hole is provided on the rear of the baffle (looking at the rear, it is to the left of the /2" drill bit and drill through the tweeter). Mount the IR sensor following the manufacturer's instructions. FRANÇAIS INTRODUCTION Nous vous remercions d'avoir choisi les enceintes encastrables B&W de la série Custom In Wall Mount (CWMTM).
