Celebrating 40 Years of Excellence: The 801 D4 Loudspeaker

Innovation Redefined: 801 D4 Loudspeakers

For four decades, the 801 series has epitomized cutting-edge loudspeaker technology. The 801 D4, the latest incarnation, showcases our newest advancements and most original thinking, solidifying its status as an iconic loudspeaker.

Unmatched Precision: The Ultimate Matrix™ Bracing

The 801 D4 features our most advanced Matrix™ bracing system yet. With interlocking panels that reinforce the cabinet walls internally, this sophisticated aluminum bracing minimizes resonance, delivering a remarkably authentic soundstage.

Revolutionary Design: The Turbine™ Head

Our all-aluminum Turbine™ Head encases the Continuum midrange cone in a rigid, critically damped enclosure, eliminating unwanted resonances. Decoupled from both the bass enclosure and the tweeter body, it achieves unparalleled midrange clarity.

Breakthrough Performance: Biomimetic Suspension

Innovation thrives on unconventional thinking. The new Biomimetic Suspension in the 801 D4 transforms midrange performance by drastically reducing unwanted air pressure and coloration from traditional fabric spiders, resulting in stunning midrange transparency.

The Science of Sound: The 801 D4

Innovation is the heartbeat of our design process. Through rigorous questioning, examination, and understanding, we evolve our loudspeakers using advanced computer modeling to reimagine every design aspect. Discover the technologies that make the 800 Series Diamond exceptional.

Flagship Excellence: The State of Our Art

The 801 D4 as the pinnacle of the new 800 Series Diamond range, embodying a no-compromise design philosophy. Integrating our most advanced technologies and premium crossover components, the 801 D4 sets a new standard for reference-quality loudspeakers, destined to be the benchmark for years to come.
