Bowers & Wilkins 603 S3 – Floorstanding Speakers for Larger Rooms
The Bowers & Wilkins 603 S3 is a passive floorstanding speaker for music and home cinema in larger rooms. Its three-way design with a dedicated midrange driver and two woofers combines detailed vocal reproduction with extended bass.
Key Features at a Glance
- Vocals and instruments: Dedicated Continuum FST midrange driver.
- High frequencies: Decoupled titanium dome tweeter.
- Bass foundation: Two woofers with paper cones and a Flowport bass reflex system.
Separate drivers for vocals, highs and bass
The Continuum midrange driver handles the range of vocals and many instruments independently of the woofers. A decoupled titanium dome handles the highs, while two separate bass drivers complete the foundation.
603 S3 and 606 S3 compared
Unlike the compact two-way 606 S3 speaker, the 603 S3 has a dedicated midrange driver and extends deeper into the bass. The 606 S3, on the other hand, requires less cabinet volume and can be placed on a suitable speaker stand.

| Concept | Three-way floorstanding speaker | Compact two-way speaker |
| Frequency range (−6 dB) | 29 Hz–33 kHz | 40 Hz–33 kHz |
