40 Years of Excellence
Innovation defines the 801 D4. In each of its incarnations over the decades, the 801 has consistently represented the most advanced loudspeaker the manufacturer knew how to build at that particular point in time, serving as a showcase of all their newest technologies and most original thinking. It is unsurprising that it has become an icon.
The Ultimate Matrix™
The all-aluminium Turbine Head houses the Continuum™ midrange cone in a stiff and critically damped enclosure to eliminate unwanted resonances. Simultaneously, it is decoupled from both the bass enclosure and the tweeter body. The result is described as the most realistic midrange sound achieved to date.
Turbine™ Head
The all-aluminium Turbine Head encases the Continuum midrange cone within a stiff and critically damped enclosure, a design choice made to eliminate unwanted resonances. Crucially, it is also decoupled from both the bass enclosure and the tweeter body. This engineering effort yields what the company states is their most realistic midrange sound yet.
Biomimetic Suspension
Making a significant difference sometimes requires unconventional thinking. The new Biomimetic Suspension revolutionizes midrange performance by substantially reducing the unwanted air pressure and coloration that a traditional fabric spider can generate. This innovation delivers a level of midrange transparency that the company claims is remarkable.
The Science of Sound
Innovation is at the core of all operations. The team questions, examines, understands, and then evolves. They utilize computer modelling to explore and reimagine every aspect of loudspeaker design. More information about all the technologies that combine to make the 800 Series Diamond so special is available here.
The State of Their Art
The 801 D4 is the flagship and most powerful model in the new 800 Series Diamond range. Its no-compromise design includes all of the manufacturer's most advanced technologies in their purest, most optimized form, alongside crossover components of the highest quality. For those seeking their reference loudspeaker, this model represents it.
