Bowers & Wilkins 603 S3 oak

The 603 S3 is the largest speaker in the 600 Series, perfect for larger rooms and home theaters. It combines our new Titanium Dome Tweeter™ with the precision and transparency of our proven midrange driver with Continuum™ cone and FST™ technology.

Sound in a class of its own
Dual woofers provide spaciousness and authority, while upgraded speaker terminals and optimized driver placement make the 603 S3 the most refined entry-level floorstanding speaker we've ever built.

Multi-layered details
The 603 S3 introduces our new titanium dome tweeter, which combines outstanding resolution and transparency with smooth, elegant high-frequency response. The result? Precise, room-filling sound that lets you experience your favorite music with even greater intensity.

Breathtaking sound
The 603 S3 features a new, acoustically more transparent tweeter grille originally developed for our coveted Signature models. Together with the new titanium dome tweeter, it provides outstanding resolution as well as fascinatingly realistic sound.

Precision and transparency
Thanks to its composite construction, the Continuum™ diaphragm eliminates abrupt transitions that can compromise the performance of conventional drivers. As a result, the 603 S3 offers a more open, neutral performance, reproducing voices and instruments with high precision and transparency.

Improved speaker terminals
Similar to the recently introduced 700 Series, the 603 S3 has also been equipped with improved speaker terminals that optimize the signal path between your amplifier and your speakers.
