Bowers & Wilkins HTM81 D4 Center Channel Speaker: Unrivaled Performance at the Heart of Your Home Theater

The Bowers & Wilkins HTM81 D4 Center Channel Speaker represents the pinnacle of audio engineering, designed to be the centerpiece of your high-fidelity home theater system. As part of the acclaimed 800 Series Diamond range, the HTM81 D4 embodies the cutting-edge technologies and meticulous craftsmanship that have made Bowers & Wilkins a legend in the world of sound.

Uncompromised Soundstage:

  • Midrange Enclosure: A meticulously crafted aluminum enclosure minimizes resonance and maximizes the performance of the midrange driver, ensuring pristine vocals and a detailed soundstage.
  • Solid Body Tweeter-on-Top: The latest iteration of this iconic design features an elongated form for an even more open and airy high-frequency response. The decoupled housing, milled from a solid block of aluminum, further reduces unwanted resonance.
  • Reverse Wrap Cabinet: This innovative cabinet construction eliminates unnecessary joints for a more rigid structure, while the curved front minimizes baffle diffraction and improves sound dispersion.

Technological Breakthroughs:

  • Matrix Bracing: Interlocking panels reinforce the cabinet walls in all directions, dramatically reducing resonance and creating a lifelike sonic image.
  • Biomimetic Suspension: This revolutionary technology minimizes unwanted coloration and distortion in the midrange frequencies, resulting in unparalleled transparency.
  • Diamond Dome Tweeter: B&W's signature diamond tweeter delivers unmatched acoustic detail, naturalism, and spaciousness, making you feel like you're right in the center of the action.
  • Continuum Cone: This innovative composite cone avoids the abrupt performance shifts common with traditional drivers, ensuring a smooth, neutral response that faithfully reproduces every sonic nuance.

Unparalleled Bass Performance:

  • Aerofoil Bass Cone: Combining a carbon-fiber skin with a variable-profile foam core, this technology achieves exceptional low-mass and high stiffness for deep, impactful bass.
  • Decoupled Midrange Assembly: By isolating the midrange driver from the bass section, this design ensures pristine vocal clarity even during the most dynamic passages.

The Bowers & Wilkins HTM81 D4 Center Channel Speaker is a testament to Bowers & Wilkins' relentless pursuit of audio perfection. It is the ideal choice for discerning listeners who demand the most immersive and captivating home theater experience possible.
