Free Shipping (Contiguous U.S. Only)

General:
The 805 D4 Signature is Bowers & Wilkins' (B&W) flagship standmount loudspeaker, representing some of the finest engineering and design found in the acclaimed 800 Series Diamond lineup.

This particular pair is finished in stunning California Burl Gloss, which we feel really does these beautiful speakers justice. The rich wood grain and deep gloss finish make them especially striking in person.

As part of the 800 Series Diamond family, the 805 D4 Signature incorporates many of B&W's proprietary technologies, including the decoupled Diamond Dome tweeter housed in its iconic solid-body aluminum enclosure, the woven Continuum cone mid/bass driver, and an upgraded Signature motor system for improved control and bass performance. Additional refinements include an optimized, acoustically transparent tweeter grille.

In our listening tests, they delivered exactly what we've come to expect from B&W: a wonderfully clear, detailed, and revealing sound with excellent imaging and surprising authority for a standmount speaker.

It's easy to understand why B&W has earned such a strong reputation in both professional and high-end home audio, and why their monitors are used in so many recording studios.

This pair includes its original B&W factory packaging, owner's manual, and accessories. The original packaging is particularly important for ensuring safe transport of these exceptional speakers.

Testing Process:
Our speaker evaluation process starts with a visual inspection of all drivers. We are looking for damaged or deteriorating woofer surrounds, dented tweeter domes, and cone damage. We also inspect the speaker connection points for loose or broken connectors.

After the initial visual inspection we connect the speakers to a reference amplifier with our preferred test tracks. With the speakers placed with proper distance we listen to each driver to make sure that they are producing the intended frequencies with no signs of distortion or rattle.

During listening tests with test tracks we check for proper stereo imaging and bass response at various listening levels. If there are any audible signs of issues, the speakers are taken to the bench where we perform a frequency sweep to isolate the issue so that it can be resolved by component repair or replacement.

Our subwoofer evaluation process starts with a visual inspection of all drivers. We are looking for damaged or deteriorating woofer surrounds, cone damage, or rubbing voice coils. We also inspect the input connections for damage.

After the initial visual inspection we connect the sub at our bench and perform a sine wave sweep from about 200 Hz down to around 10 Hz. During this sweep we are listening for excessive rattle or other signs of improper function.

If the sweep passes we then increase the input level to evaluate how the woofer performs at high output levels. If the woofer has built-in crossover adjustments or multiple connection options these features are tested at this time.

We complete the subwoofer evaluation by feeding the unit with an audio signal in conjunction with our house music system to see how it responds to low frequency content in real world conditions while paired with a full range system.
