From Abbey Road to Your Living Room

Bowers & Wilkins doesn't just make speakers—they've shaped how the world hears music. Since 1966, B&W has been the monitor of choice at Abbey Road Studios, where The Beatles, Pink Floyd, and countless legends crafted their masterpieces. The 603 S3 brings that same British obsession with accurate reproduction to the 600 Series flagship, incorporating technologies directly descended from their $30,000 800 Diamond Series.

This open-box 603 S3 in mint condition offers exceptional flexibility—sold individually, you can start with one speaker for smaller rooms or build a matched pair over time. As the largest speaker in the 600 Series, it delivers the scale and authority that makes both music and movies come alive with British refinement.

Continuum Cone—The Technology That Changed Everything

The 603 S3's 6" midrange driver features B&W's revolutionary Continuum cone—the same technology found in their reference 800 Series monitors used in the world's finest recording studios. After eight years of development, Continuum replaced B&W's legendary yellow Kevlar, delivering even greater transparency and naturalness. This woven composite material provides the perfect balance of rigidity and damping, eliminating the coloration that plagues lesser cone materials.

New Titanium Dome Tweeter Technology

The 603 S3 features B&W's all-new titanium dome tweeter—a 25-micron thick dome (about a third the thickness of human hair) with a titanium bracing ring for improved strength. Unlike the more expensive 700 and 800 series where the tweeter sits in its own housing atop the cabinet, the 603 S3 integrates this advanced tweeter directly into the main enclosure with an internal tapered tube that absorbs unwanted rear energy. The result is treble that's both silky and extended to 30kHz, never harsh or fatiguing.

Twin Paper/Aramid Bass Drivers

The dual 6.5" bass drivers employ paper cones reinforced with aramid fibers—a combination that delivers both the natural tonality of paper and the strength of synthetic materials. These drivers provide genuine bass extension to 29Hz in-room, with the control and articulation that separates British engineering from boomy mass-market speakers. The twin-driver configuration increases output capability while reducing distortion, ensuring clean bass even at party levels.

Critical Perspectives from Professional Reviews

What Hi-Fi? noted: "The 603 S3 will appeal to anyone looking for a pair of floorstanders with a full, clear sound that can fill most rooms with ease, even if they're beatable for timing and dynamics." This balanced assessment acknowledges the speakers' strengths while noting they prioritize tonal richness over rhythmic precision.

SoundStage! Access offered candid insight: "If you find neutrality boring, if you want more texture from your speakers, and if you expect a $2500 pair of tower speakers to be an eye-catching addition to a room instead of an eyesore, you should definitely find your local Bowers & Wilkins dealer and give a pair a spin." The reviewer admits these speakers play by their own rules, favoring character over clinical accuracy.

Why the 603 S3 Dominates Its Class
