Bowers & Wilkins HTM71 S3 Signature Centre Speaker - (Each)

Overview

The Bowers & Wilkins HTM71 S3 Signature takes the standard HTM71 S3's three-way design and applies the same upgrades developed for the 800 Series Signature line: upgraded bass motor systems, improved capacitors, revised speaker terminals, and a more open tweeter grille mesh. The core architecture carries over unchanged, including the decoupled Continuum FST midrange driver and Solid Body Tweeter-on-Top housing.

Those refinements are paired with two exclusive finishes, Datuk Gloss wood veneer or Midnight Blue Metallic paintwork, giving the Signature a distinct look from the standard 700 Series lineup. The three-way layout, with the midrange driver decoupled directly beneath the tweeter, keeps dialogue clarity consistent across a wide seating area rather than favouring just the centre seat.

Bi-wire/bi-amp capable rear terminals and a Flowport reflex vent carry over from the standard model, and the cabinet is sized to match the rest of the 700 Series Signature range.

Simcoe Audio Video Insight

For flagship home theatre builds across Central Ontario using the 702 S3 Signature or other Signature-line towers, the HTM71 S3 Signature is the matched centre channel that carries the same confirmed upgrades through the whole front stage rather than mixing a Signature main pair with a standard centre. The improved capacitors and revised terminals are the same ones B&W applies across its Signature range, so the upgrade is consistent rather than a one-off tweak to this single speaker.

Why the HTM71 S3 Signature Stands Out

Signature-Line Capacitor Upgrade

Improved crossover capacitors, the same upgrade applied across B&W's Signature range, for a cleaner signal path.

Upgraded Bass Motor Systems

Revised motor assemblies in the Aerofoil Profile bass drivers for improved control.

More Open Tweeter Grille Mesh

A more acoustically transparent grille mesh, as developed for the 800 Series Signature loudspeakers.

Revised Speaker Terminals

Updated rear terminals carried over from B&W's Signature-line upgrades, supporting bi-wire and bi-amp connections.

Solid Body Tweeter-on-Top

A decoupled Carbon Dome tweeter housed in a solid aluminum enclosure for open, detailed highs.

Buyer's Guide

Who It's For

  • 702 S3 Signature owners: A matched centre channel carrying the same confirmed Signature-line upgrades.
  • Flagship home theatre builds: Buyers who want the full Signature upgrade path across their front stage, not just the towers.
  • Design-conscious cinema rooms: The exclusive Datuk Gloss or Midnight Blue Metallic finishes stand apart from the standard 700 Series look.

How It Compares

The HTM71 S3 Signature shares its core three-way architecture with the standard HTM71 S3, adding the confirmed Signature-line upgrades: improved capacitors, revised terminals, upgraded bass motor systems, and a more open tweeter grille mesh, along with exclusive Datuk Gloss or Midnight Blue Metallic finishes. If you don't need the Signature-specific finishes or component upgrades, the standard HTM71 S3 delivers the same driver layout and dimensions.
