Slimmer than its predecessor, the DM603 S3 is a 2.5-way floorstander. The lower 165mm aluminium cone driver features B&W’s mushroom construction and is restricted to bass frequencies only, where it operates in parallel with the Kevlar® cone bass / midrange driver. The reduced excursion demand on the bass / midrange unit reduces distortion, not only in the bass, but also in the midrange when accompanied by heavy bass. The tweeter response in the ultrasonic region is improved for Series 3, recognizing the needs of the new high resolution recording formats. The well extended bass response and substantial output capability make the DM603 S3 fully at home in medium to large size rooms.
