A: The all-aluminum housing eliminates resonance around the midrange driver, ensuring cleaner and more lifelike vocal and instrumental reproduction.

Q: What is the benefit of the Solid Body Tweeter-on-Top?
A: It offers a more open high-frequency response by using an extended tube-loading system to reduce distortion and reflections.

Q: Can the 801 D4 be used in home theater setups?
A: Absolutely. These speakers are ideal for both audiophile-grade stereo systems and high-end multi-channel home theater environments.

Q: What is Biomimetic Suspension, and why does it matter?
A: It’s a groundbreaking suspension system that reduces midrange distortion by minimizing air pressure interference, leading to greater clarity and detail.

Q: What kind of amplifier do I need for the 801 D4?
A: Bowers & Wilkins recommends amplifiers between 50W and 1000W into 8 ohms for optimal performance.

Q: Does the 801 D4 require special speaker cables?
A: While no special cables are required, using low-impedance cables (max 0.1Ω) is recommended for best performance.

Q: How does the Reverse Wrap Cabinet affect audio performance?
A: It reduces diffraction and enhances imaging by maintaining a cleaner signal path and a more uniform sound dispersion.
