The Bowers & Wilkins 603 S3 is the largest loudspeaker in the 600 Series and is ideal for larger rooms and home theatres. It combines their new Titanium Dome™ tweeter—which offers both clarity of sound, as well as excellent high frequency dispersion—with Continuum cone technology for a truly audiophile experience.

Layered, beautiful details

The 603 S3's new Titanium Dome tweeter delivers smooth and refined high-frequency reproduction, providing an accurate and immersive insight into your favourite music. 603 S3 boasts a new design that dramatically improves the materials used in its tweeter grille mesh, first developed for our revered Signature models. The Titanium Dome tweeters provide exceptional resolution and realism.

Precision and transparency

The Continuum cone avoids the abrupt vocal transitions that can impair conventional drive units. With 603 S3, experience a more open and neutral performance—voices are delivered with precision and transparency.

Upgraded Performance

Based on the set of speaker terminals we introduced in our 700 Series, the new 603 S3's improved design offers a cleaner signal-path between your amplifier and loudspeakers.
