Improving on the last generation’s S2, the 703 S3 3-Way Floorstanding Speaker from Bowers & Wilkins in gloss black ushers in a new standard in high-fidelity sound. Whether it’s used purely for music or in a larger home entertainment system, you will enjoy dynamic sound from dual 6.5″ Aerofoil Profile woofers, a 6″ Continuum cone FST midrange, and 1″ decoupled carbon dome tweeter. The tweeter-on-top construction is more resistant to resonance, while the midrange adds biomimetic suspension to help minimize interference from the deep and dynamic bass produced by the variable thickness woofers. With the addition of a rear-firing port and updated plinth, and you have a speaker capable of truly clean, precise, and dynamic audio reproduction.




The 1″ decoupled carbon dome tweeter is featured in a tweeter-on-top design, housed in a frame that’s been milled from a single block of aluminum for better resistance to resonance. With the 703 S3, the tweeter now utilizes a carbon dome, which raises the breakup threshold to 47 kHz, further improving the accuracy of higher frequencies. Its new, more elongated form incorporates a longer tube-loading system to produce an even more free and open sound with high frequencies.

Continuum Cone Midrange

The 6″ midrange driver incorporates a composite construction that does not hinder its performance, and four Bowers & Wilkins technologies are employed where the combination ensures clean and neutral vocals and instrument representation without interference from the woofers. The four technologies used are a Continuum cone, FST, biomimetic suspension, and midrange decoupling.
