[. . . ] the CWMTM range incorporates woven Kevlar® cone mid/bass drive units for lowest coloration and maximum definition. However, no matter how good the speakers themselves, they must work well into the listening room and time spent on planning the installation will reap the reward of many hours listening pleasure. B&W distribute to over 50 countries worldwide and maintain a network of dedicated distributors who will be able to help should you have any problems your dealer cannot resolve. The speakers are designed to operate satisfactorily in a wide range of cavity volumes, ideally above 15 litres (0. [. . . ] If the speakers are placed too far apart, a hole-in-the-middle effect may become apparent. Too close and the panoramic effect will be lost, accompanied by a reduction in depth information. Use the Tilt Axis switch described above for each speaker to direct the sound either left or right towards the listening position. For Home Theatre Installations, the speakers should not be closer together than the width of the screen and their height should be approximately at centre screen height. Home Theatre Centre Channel Applications (figure 3) Theoretically, the best position for a centre channel speaker is behind the centre of the screen, but this can only be realised when using an acoustically transparent projection screen. In most cases the speaker will be positioned in a laterally central position either directly above or directly below the screen. All other things being equal, choose the position that is nearest ear height. Use the Tilt Axis switch described above to direct the sound either up or down towards the listening position. Home Theatre Surround Speaker Applications The sound from surround speakers should be as diffuse as possible. This ensures that the frontal audio image is not distorted by changes of listener position or head movements. 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). 1x Wall frame with swing out dogs · 1x Accessory pack containing: 4x Self-Tapping screws (for frame to PMK fixing) Not for CWMTM500 4x Machine screws (fixing baffles to wall frames) We suggest you retain the packaging for future use. Remove the grille and baffle from the wall frame 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. New Construction (figure 4) Fit the separately available pre-mount kit ­ (PMKTM800) 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. 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 screws visible from the front of the frame. [. . . ] Ask your dealer for advice, as the optimum cable will depend on the length required. HF Controls The switch on the front baffle provides a boost or cut in the speaker's high-frequency output. Use it to adjust the high-frequency level to compensate for severely off axis positioned speakers or heavy wall coverings (Boost) or speakers positioned in highly sound reflective rooms (Cut).
