Bowers & Wilkins 603 S3
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.

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.
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.

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.

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.
