1. DM 6 Floor standing loudspeaker system Product Summary e Early in 1972 itwas decided to fill the gap in the existing range of B amp W loudspeakers between the already successful DM 2A and the DM 70 Initally this was a fairly straightforward commercial requirement but as the development programme progressed its scope widened into the development of new measuring techniques and the use of new materials It culminated in the production of what is probably the first British Loudspeaker System to take account of relative phase between the drive units and offering a transducer that has a substantia lly minimum phase characteristic throughout the audio spectrum with the resultant improvement in the reproduction of all transient information Technical highlights e The DM 6 Bass unit operated in an enclosure volume between 51 60 litres providing a system resonance below 50 Hz e The Midrange Unit crosses over from the Bass unit at 500 Hz and operates up to the point of crossover by the HF unit which was estimated around 6kHz In view of the crossover frequencies chosen it was necessary for this unit to have a substantially linear resoonse from well below 100kHz to some 10kHz e To compliment the other two units and carry the frequency response well above 20kHz It was also felt desirable that unit should have really wide dispersion and that its diameter should be as small as possible consistent with the power handling required D2. rive Units 1 x TW 20 high frequency unit Power Handling 25W 350W voice coil diameter 19mm Dimensions Height including stand 931mm 1 x 131mm midrange unit MW 150 W idth 410mm Depth 380mm voice coil diameter 37mm Frequency Response 3dB 50Hz to 20 kHz 3 metres on axis Sensitivity 95dB atl metre Nominal Impedance 8 ohms B amp W LISTEN AND YOU LL SEE B amp W Loudspeakers Ltd reserves the right to amend details of the specifications without notice in line with technical developments E amp OE All trademarks acknowledged www bwspeakers com
