View at Bowers & Wilkins
Bi-Wire Capable

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


A celebration of sound

Room-filling scale and authority come courtesy of two bass drivers, while improved terminals and enhanced drive unit positioning make 603 S3 the most sophisticated affordable tower speaker we've ever made.


Layered, beautiful details

The new 603 S3 introduces our 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.


Truly amazing sound

603 S3 introduces our new and even more acoustically transparent tweeter grille mesh, first developed for our revered Signature models. Alongside the new Titanium Dome tweeter, the resolution and realism is exceptional.


Precision and transparency

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.


Upgraded speaker terminals

Derived from the speaker terminals recently introduced in our 700 Series range, the speaker terminals on the new 603 S3 feature an improved layout and a cleaner signal path between your amplifier and your loudspeakers.

Deliciously Crispy

The Bowers & Wilkins 603 S3 pairs a resolute Continuum midrange with an all-new titanium dome tweeter to deliver striking vocal clarity, a notably wide soundstage and surprisingly authoritative, tunable deep bass. Reviewers from What Hi‑Fi? and HiFi News highlight its clarity, dynamics and flagship-derived value at this price.

Future Audiophile

"There was more toe-tapping and head-nodding going on with them than with other speakers in this price category of audiophile loudspeakers, and isn’t that what it is all about?"

Pros

  • Transparent, detailed midrange and strong vocal presence driven by the Continuum midrange driver.
  • Deep, controlled bass with effective port tuning (two-part foam bung) for room-dependent balance.
  • Wide, well-layered soundstage and precise imaging that place instruments and voices convincingly in space.
  • Exceptional value: flagship-derived technologies (Continuum cone, upgraded crossover/tweeter) at an approachable price.

Cons

  • On-axis treble can be forward or show sibilance on some recordings; off-axis/listener positioning often tames it.
  • Rewards careful placement and benefits from more capable amplification to fully reveal dynamics and bass control.
  • Cabinet finish and plinth feel functional rather than luxurious compared with some rivals at this price.

Sound Quality

92/100

Bass

92/100

Deep extension to ~29Hz (-6dB), solid weight and punch; port and room placement affect level and tightness. Reviews note excellent low-end authority and control but some say ultimate slam benefits from a sub or boundary gain.

Mid

94/100

Continuum 150mm mid praised repeatedly for clarity, vocal presence and natural timbre. Multiple reviewers cite striking vocal detail and coherence through the crossover region.

Treble

89/100

New titanium dome tweeter delivers detail and air, with several reviews noting slight forwardness/on‑axis energy and occasional sibilance that can be mitigated by toeing the speakers out.

Soundstage Imaging

92/100

Consistently praised for wide, deep and well-layered soundstage with focused imaging; many reviewers report excellent instrument placement and a convincing sense of space.

Dynamics

89/100

Generally very good macro- and micro-dynamics and high output without distortion; a minority of reviews find them slightly restrained compared with the most exciting rivals, so not uniformly breath-taking.

Show Less

Build Quality

90/100

Solid, well-braced cabinets, quality plinth and tidy finishes; magnetic grille and packaging praised. A few comments flagged the cabinet finish as functional rather than luxurious.

Features Connectivity

80/100

Passive tower baseline applied: rear Flowport with supplied foam plugs, bi-wire/bi-amp capable twin binding posts; no DSP/streaming expected or penalized.

Value for Money

92/100

Multiple reviewers call the 603 S3 an excellent value at its asking price, offering flagship-derived tech and very competitive performance for the money.
