B&W DM603 S3 Speakers

Slimmer than its predecessor, the DM603 S3 is a 2½-way floorstander. The lower 165mm (6½-in) aluminium cone driver features B&Ws 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 result is greater clarity at higher replay levels.
