Bowers & Wilkins 603 S3 Floorstanding Speakers

The most significant introduction to the new 600 Series S3 is an all-new tweeter dome technology, the Titanium Dome. The new tweeter is a two-part construction, with a very thin, light but rigid 25-micron main dome, braced by a second 30-micron titanium ring. This new design is housed in a significantly elongated tube-loading system, inspired by the design recently introduced in the new 700 Series S3. The longer tube loading system reduces the resonant frequency behind the dome and leads to a more open sound that is less impacted by the cabinet that houses it.

In addition, the new Titanium Dome benefits from a 700 Series S3-sized diaphragm mounting plate for better, more open dispersion and also includes the very latest, more open tweeter grille design taken directly from the recently introduced 800 Series Signature.

Crossovers are also updated with the inclusion of high quality, upgraded bypass capacitors from the 700 Series S3, delivering higher resolution and transparency.

Bowers & Wilkins’ proprietary Continuum Cones continue to feature throughout the new 600 Series S3 range with the addition of more powerful, lower distortion 700 Series S3 motor assemblies for midrange and bass/midrange drive units. The paper cone bass drivers in the 603 S3 also now feature 703 S3 motor systems. Crossovers are also updated with the inclusion of high quality, upgraded bypass capacitors from the 700 Series S3, delivering higher resolution and transparency.

On the rear of the speaker, a new terminal tray, taken from the 700 Series S3, is joined by a 700 Series specification bass port, improving performance and creating a stiffer cabinet. The enclosure’s rigidity is further improved by upgrading the internal bracing to a higher standard of wood.
