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

The new 603 S3 introduces the 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.

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.
