bending wave Audio - fundamentally different.




  • No cross-over within the entire vocal range
  • Odd-order distortion nearly immeasurable
  • Clean, clear intelligibility

Resonant mode speakers are wide band-width devices, with very low 3rd-order harmonic distortion.

Conventional speakers use tweeters or compression drivers which are then crossed over to a midrange driver. This crossover is typically within the vocal range, around 800Hz to 1.8kHz, causing lack of intelligibility.

  • Diffuse energy vs. directed pistonic wave front
  • Reflected energy is nondestructive
  • Secondary reflections do not muddle words

A diffuse sound source is created by exciting a resonant panel, much like a string exciting the body of a guitar. Tectonic does this with exciters and carbon fiber, Nomex honeycomb panels.

The nature of this diffuse source is that it significantly reduces destructive reflections (audible echoes or “slap-back”), thus providing the benefit of clear sound, even in reverberant spaces like gyms, cathedrals, etc...

wide stable imaging

  • Wide 165° coverage
  • Equal at all frequencies; does not ‘beam’
  • Sharp initial impulse provides precise imaging

Resonant mode audio provides a very wide coverage area, compared to conventional pistonic speakers. And they do so at all frequencies, unlike conventional speakers that change coverage patterns with increased frequency.

Also, because the panels exhibit a very sharp impulse response, they provide a very strong image, with compelling stereo or surround sound, even when seated off-center from the speakers.

high feedback resistance

  • Already resonant at all frequencies
  • Difficult to excite into feed-back mode
  • Open mics usable in front of speakers

Resonant mode loudspeakers are designed to resonant at all frequencies in the operating bandwidth, so they are extremely difficult to excite into a feed-back mode in these frequencies.

Open mics can be used in front of Tectonic speakers. However, caution should always be exercised on microphone selection and use, since any system will feedback, including Tectonic Plates in certain applications.

  • Flexible rigging for quick setup/install
  • Thin, light-weight panels
  • Architectural
  • Reduced transit costs

Architects, consultants and sound designers benefit from the low weight, which reduces infrastructure requirements, and the acoustically friendly performance which can reduce or eliminate acoustic treatments.

Flexible and light-weight rigging makes hanging arrays for any coverage quick and easy. The system packs into a few, compact road cases, saving in transport and labor costs.

  • “Tectonic Audio Labs' new speaker system designs are a major leap forward in the evolution of sound quality, price and performance in the audio markets for touring, installations and consumer products.”

    Brian Bell - Herbie Hancock, John McLaughlin, Weather Report, Chick Corea

  • “I think, because of the sound quality and the size, it’s unbelievable. It’s new technology. It’s going to change the face of touring. No longer will you need a semi-truck to put a huge sound rig in. I’m really impressed.”

    Larry Knight – Jimmy Buffet, IMPACT

  • “As thin as these speakers are, they can’t sound that big, right?… They had a humongous sound that was absolutely earth shattering. I was amazed at how great sounding these speakers were. You could use these for Front of House. It’s a whole new ballgame with these speakers.”

    Herbie Hancock

  • "Shocked isn't even close to how I feel after hearing the Tectonic system in my venue. This is the next step in live audio. Tectonic just proved my assumptions wrong. This has just blown my mind. What is this? Witchcraft?!!"

    Isaac Taylor – Technical Director - Olympia Theater, Miami

  • “You will hear the future. This is the best upgrade in audio since the condenser mic. There is no denying this major leap for pro-audio. Find a way to experience this stuff! I've heard it. It's impressive.”

    Dan East - The Mix Doctor

  • “Whether for rock or quiet material, the difference with the Tectonic system is dramatic. The soundstage and instrument separation in the mix is more defined. Now, when I hear acoustic music in this room, I’m in heaven.”

    Don Bassey - Empress Theatre, Vallejo, CA

  • “Beautiful, clear, crisp and excellent sounding. Everything about these speakers is phenomenal. Tectonic is introducing a new paradigm. With the Tectonic speakers behind my orchestra, everyone can hear their performance in context and it’s a very holistic experience.”

    Roy “Futureman” Wooten – Artist, Composer, Bela Fleck & The Flecktones

  • “The Tectonic speaker system is really mind boggling. I swear I am switching it out in every design I have on the table right now. Can you say ‘back to the drawing board?’ ”

bending wave audio vs. pistonic Technology



bending wave Audio

Sound in Bending Wave  Audio loudspeakers is created by “exciting” a specially designed panel.

The Tectonic Plates employ a thin carbon fiber-laminated Nomex honeycomb panel.  The panel is excited by electro-magnetic motors.  Collectively, this device, or transducer, is called a DML (distributed mode loudspeaker).

Using a method similar to a string exciting and resonating the body of an acoustic instrument - like a guitar or violin - the DML produces a predominantly diffuse sound source, versus a point source in conventional pistonic speakers.  This provides the unique benefits described above. 

One key behavior is that a diffuse sound source is analogous to a room diffusor (specialized room treatment), which is designed to scatter acoustic reflections.  A diffuse source reduces focused reflected sounds, which increases intelligibility.

traditional PISTONIC

Traditional loudspeakers use uniform pistonic motion to create sound.

The goal of piston design is to not “break up” or resonate.  This is exactly the opposite goal of a DML, which is designed to resonate equally at all frequencies in its bandwidth. This fundamental difference solves perennial problems with pistonic designs including:

  • Focused reflections correlated to the original sound source, reducing intelligibility
  • Coverage that changes with frequency, called “beaming”
  • Multiple transducers with crossovers in the vocal range, especially affecting female vocals
  • High distortion when played loud is fatiguing and unpleasant for listeners
