Bowers & Wilkins 704 S3 Floor Standing Speakers - (Pair)
Overview
The Bowers & Wilkins 704 S3 is the slimmest floorstanding speaker B&W makes, a three-way 700 Series tower that B&W says still packs a mighty punch. It uses a Decoupled Carbon Dome tweeter, a decoupled 5-inch Continuum cone FST midrange, and two 5-inch Aerofoil Profile bass cones in a cabinet 165 mm (6.5 in) wide.
The Carbon Dome tweeter, purpose-built for the 700 Series, raises the breakup threshold to 47kHz. Like every three-way 700 Series model, it uses a dedicated midrange that combines four B&W technologies: the Continuum cone, FST, Biomimetic Suspension, and midrange decoupling, which keeps interference from the bass drivers to a minimum. The twin Aerofoil bass cones give the slim cabinet its extension and scale.
B&W rates the 704 S3 at 48Hz to 28kHz (±3dB), with a range of 43Hz to 33kHz, 88dB sensitivity, and an 8-ohm nominal load, suited to amplifiers from 30W to 150W. Each speaker stands on a supplied plinth.
Simcoe Audio Video Insight
The 704 S3 is the 700 Series tower for rooms where width is the limit: the cabinet is 165 mm wide and 252 mm with its plinth. If it has to sit close to a wall, the supplied two-piece foam plug lets you trim the bass. The terminals support bi-wiring or bi-amping once the links are removed.

Why the Bowers & Wilkins 704 S3 Stands Out
Slimmest B&W Floorstander
A cabinet just 165 mm (6.5 in) wide, B&W's slimmest floorstanding speaker.
Decoupled Carbon Dome Tweeter
Purpose-built for the 700 Series, B&W's Carbon Dome tweeter raises the breakup threshold to 47kHz for pinpoint imaging and detail.
Continuum Cone FST Midrange
A decoupled midrange with Biomimetic Suspension that avoids the abrupt transitions of conventional cones, for precise, transparent voices.
Two 5-Inch Aerofoil Profile Bass Cones
Developed with computer modelling, the variable-thickness Aerofoil cone adds stiffness where it matters for deep, dynamic bass.
Two-Piece Foam Plug
Fit the outer ring alone or the full plug to fine-tune bass when the speakers sit near a wall.
Bi-Wire and Bi-Amp Terminals
Remove the terminal links to bi-wire or bi-amp; B&W notes bi-wiring can improve the resolution of low-level detail.
Plinth with Spike and Rubber Feet
Each tower stands on its supplied plinth, which B&W says must always be used, with spike or rubber feet.
Buyer's Guide
Who It's For
- The Narrow-Room Owner: Wants a floorstanding speaker where width is limited.
- The Home Theatre Builder: Wants slim front towers that suit the room's look.
- The Two-Channel Listener: Wants three-way 700 Series sound in a mid-sized room.
How It Compares
The 704 S3 is the slimmest 700 Series tower, using 5-inch drivers and no Tweeter-on-Top housing. The 703 S3 steps up to the Solid Body Tweeter-on-Top, a 6-inch midrange, and two 6.5-inch bass cones.
