Experience reference-grade audio with the Bowers and Wilkins 803 D4 Floorstanding Speakers, the most compact model in the 800 Series Diamond range to feature the iconic Turbine Head enclosure. Designed for smaller spaces without compromising performance, these speakers deliver exceptional clarity and depth through advanced technologies like the Continuum cone FST and Aerofoil bass units.

With a frequency response of 19 Hz to 28 kHz and a sensitivity of 90 dB, the Bowers and Wilkins 803 D4 Floorstanding Speakers are ideal for both stereo listening and home theater setups. At Len Wallis Audio, this brand-new pair, sealed in its original packaging, is ready to bring high-fidelity sound to your home.

Why Choose the Bowers and Wilkins 803 D4 Floorstanding Speakers?

The Bowers and Wilkins 803 D4 Floorstanding Speakers bring the technical prowess of the 800 Series Diamond range into a compact design, perfect for any home without sacrificing sound quality. The Turbine Head enclosure, a rigid aluminum housing for the 5-inch Continuum cone FST midrange driver, minimizes resonances to deliver pure, undistorted sound, making vocals and instruments come alive with stunning realism.

The innovative Biomimetic Suspension replaces traditional fabric spiders, reducing air pressure and coloration for midrange transparency that reveals every detail in your music. Whether you’re listening to jazz, classical, or a movie soundtrack, these speakers create an expansive, lifelike soundstage that immerses you fully.

The 1-inch diamond dome tweeter, housed in a revised Solid Body Tweeter-on-Top with an elongated tube-loading system, produces open, airy highs up to 35 kHz, while dual 7-inch Aerofoil cone bass units extend low frequencies down to 19 Hz with precision, thanks to their carbon-fiber skin and foam core. The upgraded cabinet features a cast aluminum top section for added stiffness, finished with luxurious Leather by Connolly trim—black for Gloss Black and Satin Rosenut finishes, or light grey for White and Satin Walnut.

At 1165 mm tall and 62.15 kg, the Bowers and Wilkins 803 D4 Floorstanding Speakers blend elegance and performance, ideal for audiophiles seeking quality in smaller spaces. Sound is subjective, though—the true test is in your ears. Visit our Lane Cove showroom to audition the Bowers and Wilkins 803 D4 Floorstanding Speakers and discover their magic for yourself.
