Its 59-litre enclosure accommodates two 8in low frequency units, which utilise 56 litres of volume. The bass performance is further enhanced by the use of heavier Cobex cones in the lowfrequency drivers, delivering in the process a lower fundamental resonance frequency. ● Unique to the DM640 is a separate, acoustically isolated 160mm midrange drive unit mounted in its own sub-enclosure, By employing the B&W innovation of Kevlar for the cone material and relieving the unit of the need to reproduce high-excursion bass frequencies.
