Bowers & Wilkins 603 S3 (pair)

A celebration of sound

Fullness and room presence are provided by the two bass drivers. Improved binding posts and better speaker positioning make the 603 S3 the most sophisticated affordable floorstanding speaker we've ever built.

Exceptional layering of detail

The new 603 S3 incorporates our all-new titanium dome tweeter, which combines exceptional resolution and detail with smooth, refined high-frequency reproduction. The result? A precise, immersive rendering of your favorite music.

Truly astonishing sound

The 603 S3 features our new, even more acoustically transparent tweeter grille, developed for the first time for our Signature models. Combined with the all-new titanium dome tweeter, the result is exceptional resolution and realism.

Precision and transparency

Thanks to its composite construction, the Continuum diaphragm avoids the abrupt transitions in behavior that can impair the performance of a conventional loudspeaker. As a result, the 603 S3 delivers a more open, neutral soundstage, enabling vocals and instruments to be reproduced with precision and transparency.

Improved speaker terminals

Derived from the connection terminals recently introduced in our 700 Series range, the speaker terminals of the new 603 S3 feature an improved layout and a more direct signal path between your amplifier and your speakers.

The essential speakers for music lovers.
