WHAT IS A WATERFALL PLOT?

A Waterfall Plot is the industry standard for measuring resonance in audio speaker drivers.

The spectrum of human hearing ranges from 20Hz to 20,000Hz. Many of us cannot hear above 15,000Hz. The test works by sending a pulse of all audio frequencies, at the same loudness, through an audio speaker driver, (headphones, home-audio, etc.) then cutting the signal. The faster the energy (vibration) drops or decays, across the spectrum of human hearing, the less unwanted resonance is present, therefore the less distorting pollution there is to interfere with your music.

THIS IS THE BEST WATERFALL PLOT EVER MEASURED

Grail Zero-Resonance waterfall

The Waterfall Plot above was generated by Wing’s midrange-treble headphone driver. It has been described as truly exceptional by Audio Engineers who have also stated that this result would be impossible using conventional drivers.

The |zero-resonance-distortion| bandwidth is an incredible 150Hz to 18,000Hz – across almost the entire spectrum of human hearing – impossible until now.

It is irrefutable proof that the acousticWING™, employing a rigid operating system, is the only audio transducer in existence that can deliver zero-resonance sound, over the widest possible bandwidths. The result is the purest sound definition you will ever hear.

The acousticWING™ liberates your music.

Competition Brand Waterfall Plot

The image above is a Waterfall Plot from one of the world’s leading reference headphones. It is considered by many reviewers to be the pinnacle of conventional technology. It is saturated with resonance modes (unwanted vibrations) through almost the entire spectrum of human hearing.

This resonance significantly degrades the purity of the original audio recording, resulting in a muddiness through the mid and upper frequency ranges that masks the true sound definition.

The images above represent Waterfall Plots from world-renowned headphone drivers. The jelly-like properties and floppy piston-action, of these conventional loudspeaker drivers, shake masses of distorting-resonances (unwanted vibrations) through almost the entire spectrum of human hearing. This unavoidable polluting energy is released directly into your music, significantly degrading sound quality.
