DM6

Floor-standing loudspeaker system

Product Summary

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.

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

The DM6 Bass unit operated in an enclosure volume between 51-60 litres providing a system

resonance below 50 Hz.

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 response from

well below 100kHz to some 10kHz.

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.
