EXPERIENCE THE
SHIFT IN AUDIO

Tectonic creates sound in a new way, using bending wave technology to provide an immersive sound experience that is highly tolerant of difficult environments. Tectonic loudspeakers use composite panel technology instead of the traditional cone diaphragm.

SPEAKER 101

In the last 100 years, loudspeaker technology has been dominated by the dynamic loudspeaker drive unit with other technologies emerging, i.e. electrostatic and magneplanar.

1925

Modern Dynamic Loudspeaker Drive Unit Patented

General Electric engineers, Chester Rice and Edward Kellogg, publish an article proposing a ‘new type of hornless loudspeaker’. This is based around a conical paper diaphragm with attached voice coil energized by a large magnet structure. Nearly all conventional moving coil drive units in market today still bear a strong resemblance to this design.

1954

Acoustic Suspension Loudspeaker Invented

American inventor Edgar Villchur creates a new method of mounting the drive unit into a sealed enclosure of given air volume. This gives much improved bass response and reduced distortion, relying on the air spring from the enclosure for restoring force more heavily than the stiff motor suspension element typical of the day.

1997

Distributed Mode Loudspeaker (DML) Conceived

Following work by the UK’s Ministry of Defense into reducing noise in aircrafts, NXT was formed to research and commercialize this novel approach to loudspeaker design. Now, the strong link between the size of a speaker and its bandwidth was finally broken, utilizing a complex arrangement of optimally spaced bending wave modes in a flat, composite panel to produce the sound. Tectonic Audio Labs acquired the rights to DML for sound reinforcement in 2012.

A TALE OF TWO TECHNOLOGIES

In traditional speakers, pictonic vibrations of the cone diaphragm produces the sound. In Tectonic loudspeakers, the sound is produced by complex bending wave vibration patterns.

TRADITIONAL PISTONIC SPEAKER

TECTONIC DISTRIBUTED MODE LOUD SPEAKER

BENDING WAVE AUDIO

Loudspeakers featuring this technology utilize bending waves excited into complex modal patterns to produce sound. This is in contrast to the push-pull pumping action of a pistonic cone speaker. Bending wave modal vibration patterns stimulate the air into motion and the complexity of the pattern ensures wide directivity and can lead to a largely diffuse radiation character.
