User manual B&W DM6

[. . . ] [. . . ] DM6 Floor-standing loudspeaker system Product Summary q Early in 1972 it was decided to fill the gap in the existing range of B&W loudspeakers between the already successful DM2A and the DM70. Initially 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. q 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 substantially minimum phase characteristic throughout the audio spectrum, with the resultant improvement in the reproduction of all transient information. Technical highlights q The DM6 Bass unit operated in an enclosure volume between 51-60 litres providing a system resonance below 50 Hz. q 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.
