Overview

The Bowers & Wilkins 607 S3 represents the smallest model in the third generation of B&W’s 600 Series. This 2-way bass reflex speaker features a 25mm titanium dome tweeter and 16.5cm Continuum cone driver, offering considerable technical sophistication at the USD 750 price point. The deployment of Continuum cone technology, originally developed for the company’s flagship 800 Series, to this entry-level model, combined with the material transition from aluminum to titanium, aims to improve high-frequency characteristics. With dimensions of 300×166×235mm and weighing 4.7kg, it maintains standard proportions for its class.

Scientific Validity

\[\Large \text{0.8}\]

Measurement data shows frequency response coverage of 52Hz-28kHz with 84dB sensitivity, representing a relatively demanding design for amplification. The combination of titanium dome tweeter and Continuum cone produces measurably different performance compared to conventional aluminum dome and paper cone designs. Particularly in high-frequency distortion characteristics and transient response, improvements identifiable in blind testing have been confirmed. However, at this price point, the technology cannot be considered revolutionary, and competing products achieving equivalent measured performance do exist.

Technology Level

\[\Large \text{0.7}\]

Technically, the deployment of Continuum cone technology, developed for B&W’s higher-end 800 Series, to this entry-level model deserves recognition. The titanium dome tweeter also represents a material upgrade from aluminum, theoretically contributing to improved high-frequency characteristics. However, the fundamental 2-way design follows industry standards, with no particularly innovative technological breakthroughs evident. The enclosure design also adheres to conventional approaches, placing the technical level at slightly above industry average.

Cost-Performance

\[\Large \text{0.4}\]

At USD 750, competitive 2-way bookshelf speakers with equivalent measured performance include the Q Acoustics 3020i (USD 300, frequency response 64Hz-30kHz, sensitivity 88dB) as the most affordable option. Comparing measurement data, the 607 S3 offers 52Hz-28kHz frequency response with 84dB sensitivity, while the 3020i provides 64Hz-30kHz with 88dB sensitivity. The 3020i is easier to drive, while the 607 S3 extends slightly deeper in bass, but practical performance differences are limited. Additional equivalent-performance alternatives include ELAC Debut 2.0 B6.2 (USD 400) and KEF Q150 (USD 550). Calculation: CP = USD 300 ÷ USD 750 = 0.40. Considering that equivalent functional performance is available at less than half the price, cost-performance remains at a limited level.

Reliability & Support

\[\Large \text{0.8}\]

B&W, with over 75 years of history, is a well-established manufacturer whose product reliability is highly regarded in the industry. The 5-year warranty period is adequate, with service centers deployed globally. Long-term parts supply is maintained, and repair systems are well-established. However, some users have expressed improvement requests regarding after-sales service response times and technical support quality.

Rationality of Design Philosophy

\[\Large \text{0.8}\]

The 607 S3’s design philosophy represents a rational approach that remains faithful to passive speaker fundamentals while pursuing technical refinement. At the USD 750 price point, advanced technologies like Continuum cone technology and titanium dome tweeter are incorporated to improve measured performance. Bass reflex design realizes extended low-frequency response, while dual terminal design accommodates bi-wiring. The passive speaker design philosophy is rational in providing amplifier selection flexibility and ensuring overall system adaptability.

Advice

The 607 S3 offers favorable balance between technical sophistication and sound quality at the USD 750 price point. Equivalent-performance competitive products include the Q Acoustics 3020i (USD 300) as the most affordable option, along with ELAC Debut 2.0 B6.2 (USD 400) and KEF Q150 (USD 550), requiring careful comparison when cost-performance is prioritized. When considering purchase, first confirm appropriate amplifier pairing. With 84dB sensitivity, adequate amplifier output is essential. In audition environments, conduct comparative listening with products like the KEF LS50 Meta (USD 1,300) and Monitor Audio Silver 50 (USD 800) to confirm performance differences justifying price differentials.
