User manual B&W DM 302

[. . . ] Since its foundation in 1966, the continuing philosophy of B&W has been the quest for perfect sound reproduction. Inspired by the company's founder, the late John Bowers, this quest has entailed not only high investment in audio technology and innovation but also an abiding appreciation of music to ensure that the technology is put to maximum effect. It is also our policy to make sure the advanced features pioneered on one product are incorporated into others we manufacture. [. . . ] Speaker stands should be regarded as part of the speaker and chosen with care. (figure 3) Some experimentation with the position of the speakers is well worthwhile to optimise the interaction between them and the listening room. However, as an initial guide: Place the speakers on firm stands or bookshelves that place the tweeters approximately at ear level. place the speakers and the centre of the listening area approximately at the corners of an equilateral triangle. Having the speakers too close to walls increases the level of bass relative to the midrange and may give a boomy quality to the sound. NOTE: The DMTM302 produces a static magnetic field that extends outside the cabinet boundary. If you wish to use an aerosol cleaner, remove the grille first by gently pulling it away from the cabinet. The grille fabric may be cleaned with a normal clothes brush after removing the grille from the cabinet. Avoid touching the drive units, especially the tweeter, as damage may result. Before fine tuning the installation, double check the polarity and security of the connections. If the level of bass is uneven with frequency, this is usually due to strong excitation of resonance modes in the room. Even small changes in the position of the speakers within the listening room can have a profound effect on the perceived sound quality by altering the excitation of these modes. If the general level of bass is too high, try moving the speakers further away from the walls. Conversely, if you need more bass, move the speakers closer to the walls. [. . . ] Failure to observe correct polarity will result in poor sound balance and image focusing. Always make sure all the terminal caps are screwed down tight, as otherwise they may rattle. When choosing cable, keep the total electrical impedance (out and back) below the maximum Reserves the right to amend specifications without notice in line with technical developments. [. . . ]
