If greater efficiency and bass extension are called for then the DM320 with its larger enclosure and the 3-way system comes into its own. ● Equipped with two 8in bass units in a closed box configuration and the acclaimed magnetic fluid-cooled, light-alloy domed tweeter offers an extended low frequency range with higher sensitivity. Technical highlights ● The use of a aluminium domed tweeter immediately distinguishes the two models. The specially created 26mm (1in) tweeter enables high power handling to cope with the heavier usage imposed on modern hi-fi systems. Frequencies in excess of 20kHz are within its range. ● Subtle changes to the cabinet such as the tweeter plate, and bevelled front edges of the cabinet, help produce a dramatically more even frequency response. The B&W tradition of attention to detail manifests itself other features, such as the reinforced low-frequency driven diaphragm, the rigid die-cast chassis, and the provision for bi-wiring or bi-amplification.
