Evolution of the 600 Series

The 600 Series has seen several updates over the years, and the S3 generation brings it to a new level of technological prowess.

Impressive Sound Configuration

The 603 S3 boasts a three-way design with a 6-inch midrange driver equipped with a silver Continuum cone and two 6.5-inch woofers featuring paper cones. The well-designed bass port at the rear operates quietly. This speaker’s 8-Ohm impedance and relatively high sensitivity of 90 dB contribute to its ease of driving. Even with compact amplifiers, the 603 S3 delivers a good sound, though more power brings out its full potential.

The sound configuration of Bowers & Wilkins’ 603 S3 floorstanding speaker is a prime example of the engineering excellence and meticulous design that defines this audio product.

Three-Way Design: The 603 S3 features a three-way speaker design that combines a 6-inch midrange driver with a Continuum cone and two 6.5-inch woofers with paper cones. This configuration is carefully calibrated to deliver a balanced and accurate sound reproduction across the audible spectrum. A three-way design ensures that different frequency ranges are handled by dedicated drivers, minimizing interference and phase issues that can occur in less sophisticated speaker configurations.

Continuum Cone Technology: Including Bowers & Wilkins’ renowned Continuum cone material for the midrange driver is a standout feature. The Continuum cone is designed to reduce distortion and provide a more controlled and precise sound. This driver plays a pivotal role in the midrange frequencies, where vocals and many musical instruments reside. The result is a clear and natural representation of these critical elements, enhancing the overall listening experience.

Robust Woofers: The two 6.5-inch woofers with paper cones work in concert to deliver a solid bass foundation. These drivers are engineered to handle low-frequency content with accuracy and power. The rear bass port of the speaker, designed with the expertise that Bowers & Wilkins is known for, ensures that the low end is extended and deep without compromising on clarity. The woofers add depth to the sound, enhancing the overall presence of the music.

Efficient Sound Dispersion: The sound configuration of the 603 S3 is optimized for efficient sound dispersion. This means that the speaker can fill the room with music in a way that is both enveloping and natural. It doesn’t just project sound directly at the listener but creates an immersive soundstage that feels as if the music is emanating from all directions. This three-dimensional quality adds depth to the listening experience, making it feel as if you are right in the midst of a live performance.

Controlled High-Frequency Delivery: The integration of the titanium tweeter, which boasts an ultra-thin dome and advanced sound-tuning technology, contributes to the controlled and precise high-frequency response. The tweeter’s thin dome allows for fast and accurate sound reproduction, capturing the fine details and harmonics in the music. It delivers high frequencies with exceptional clarity and accuracy, ensuring that the treble elements of the music are faithfully rendered.

Adaptive Amplification: The 603 S3, while not demanding, benefits from a quality amplifier to unlock its full potential. While it can perform well with compact amplifiers, providing a satisfactory listening experience, more powerful amplifiers add an extra level of control in the bass and enhance the openness of the sound image. This adaptability speaks to the versatility of the speaker and its ability to cater to a wide range of audio systems and listening preferences.

In summary, the impressive sound configuration of Bowers & Wilkins’ 603 S3 is a testament to the company’s dedication to delivering an exceptional listening experience.

The Heart of the 603 S3: The Tweeter

The tweeter in Bowers & Wilkins’ 603 S3 floorstanding speaker stands as the heart of its sound configuration, playing a pivotal role in delivering an exceptional audio experience.

Titanium Tweeter Innovation: The 603 S3 features a titanium tweeter, an innovation that reflects Bowers & Wilkins’ commitment to using advanced materials for their speakers. This choice is significant because it ensures that the tweeter’s dome is extremely thin, measuring 25 microns. Despite its delicate dimensions, this titanium tweeter remains remarkably rigid. This rigidity is essential as it allows the tweeter to faithfully reproduce high-frequency sounds precisely and accurately, capturing the finest details and harmonics in the music.

Optimized High-Frequency Reproduction: The ultra-thin titanium dome, combined with advanced sound-tuning technology, contributes to the controlled and precise delivery of high-frequency sounds. The 603 S3 can render treble elements, such as cymbals, violins, and female vocal harmonies, with exceptional clarity and accuracy. It captures the brilliance and intricacy of these high-frequency components, ensuring they are lifelike. This level of precision elevates the listening experience, allowing listeners to fully appreciate the subtle nuances within their favorite tracks.

Inherited Acoustic Excellence: It’s worth noting that the 603 S3 inherits some of the acoustic excellence found in Bowers & Wilkins’ higher-end speaker series. The innovative features of the tweeter, such as the ultra-thin dome and sound-tuning technology, have been passed down from the brand’s more premium models. This transference of technology is a testament to Bowers & Wilkins’ commitment to offering the same quality and innovation across their product range, ensuring that even entry-level speakers benefit from the advancements made in their flagship products.

Balancing the Audio Equation: The tweeter in the 603 S3 plays a crucial role in balancing the audio equation. While the midrange driver and woofers handle the lower frequencies and vocals, the tweeter takes responsibility for the high frequencies. This division of labor ensures that each component is specialized in function, minimizing interference and distortion. The result is a sound configuration that is clear, coherent, and faithful to the original recording.

In conclusion, the tweeter in Bowers & Wilkins’ 603 S3 is not merely a component; it’s the heart of the speaker’s sound profile. Its innovative use of titanium and advanced sound-tuning technology ensures that high-frequency sounds are delivered with exceptional accuracy and clarity. This focus on the tweeter, an integral part of the speaker’s overall sound configuration, exemplifies the brand’s commitment to providing a refined and authentic listening experience, even in their more accessible audio offerings.
