GRAVITONI

Some things are heard.
Others are felt.

A laboratory dedicated to the bottom end of sound: bass, sub-bass, acoustics, resonance, LFE, psychoacoustics and the science of low-frequency reproduction.

The double meaning

GRAVITONI.
Or perhaps
GRAVI TONI.

In physics, the graviton is the hypothetical quantum associated with gravity. In Italian, split the word differently and something else appears: gravi toni — low tones. Gravitoni lives precisely between those two worlds: physics and sound.

Down the spectrum

The lower we go,
the more interesting it gets.

Low Bass

Weight, fundamentals and the lower region of musical reproduction.

60–120 Hz
Sub Bass

Energy increasingly perceived physically as well as aurally.

20–60 Hz
Deep Bass

The extreme bottom octave of conventional audio reproduction.

20–40 Hz
Infrasound

Below the conventional lower boundary of human hearing.

< 20 Hz
Research areas

Everything that happens down there.

01

Acoustics

Wavelengths, room modes, resonances, boundaries and low-frequency behaviour.

02

Subwoofers

Placement, crossover, phase, calibration and integration with monitoring systems.

03

LFE

Low Frequency Effects, multichannel reproduction, cinema and immersive audio.

04

Production

Kick and bass relationships, synthesis, recording, mixing and mastering.

05

Psychoacoustics

Where hearing becomes sensation and sound begins to be perceived physically.

06

Measurement

Frequency response, phase, decay, room analysis and practical acoustic testing.
