Bowers & Wilkins 603 S2 Anniversary Edition

Performance Evolved

For 25 years we have poured the same passion for performance into our most affordable loud speakers as we have into our flagship Bowers & Wilkins 800 Series Diamond range. We want more people to hear music the way we hear music – as the artist intended. Now, 600 Series has turned 25 – and we are celebrating in style. Introducing the 600 Series Anniversary Edition.

The 603 S2 Anniversary Edition is the largest and most capable loud speaker in the 600 Series Anniversary range. A tower speaker designed to offer great power accuracy and musicality. Perfect for larger rooms and also ideal for home theater. Available in a new wood effect finish as well as black and white.

The powerful 603 S2 Anniversary Edition tower speaker combines the accuracy and transparency of our acclaimed Continuum™ mid range cone with the scale and authority of two dedicated bass drivers. Featuring upgraded crossovers for even more transparency and a unique trim ring to celebrate its status, the 603 S2 Anniversary Edition is the most sophisticated affordable tower speaker we’ve ever made.
