B&W Bowers and Wilkins 603 S3 FloorStanding Speaker

The 603 S3 is the largest loudspeaker in the 600 Series and is ideal for larger rooms and home theaters. It combines our new Titanium Dome™ tweeter with the accuracy and transparency of our acclaimed Continuum™ cone FST™ midrange driver.

 A celebration of sound 

Room-filling scale and authority come courtesy of two bass drivers, while improved terminals and enhanced drive unit positioning make 603 S3 the most sophisticated affordable tower speaker we’ve ever made.

 Layered, beautiful details 

The new 603 S3 introduces our all-new Titanium Dome tweeter, which combines exceptional resolution and insight with smooth, refined high-frequency reproduction. The result? An accurate and immersive insight into your favorite music.

Truly amazing sound

603 S3 introduces our new and even more acoustically transparent tweeter grille mesh, first developed for our revered Signature models. Alongside the new Titanium Dome tweeter, the resolution and realism is exceptional.

 Precision and transparency 

Thanks to its composite construction, the Continuum cone avoids the abrupt transitions in behavior that can impair the performance of a conventional drive unit. With 603 S3, experience a more open, neutral performance that delivers voices and instruments with precision and transparency.

 Upgraded speaker terminals

Derived from the speaker terminals recently introduced in our 700 Series range, the speaker terminals on the new 603 S3 feature an improved layout and a cleaner signal path between your amplifier and your loudspeakers.
