Every Seat. Every Word.

Tectonic Resonant Mode Loudspeaker Systems solve the perennial problems that churches have faced for decades. There is finally a simple solution that you can choose to assure that every service is heard and understood.

Tectonic Resonant Mode Loudspeakers produce audio in a way that is fundamentally different from traditional point-source speakers. Our exclusive Distributed Mode Loudspeaker (DML) mid-range panels propagate audio energy by ‘exciting’ a large flat panel versus pushing a pistonic cone or dome back and forth.

The performance advantages in even the most difficult acoustic spaces are a revolution in providing sound reinforcement for worship.

Minimal Interaction with Reverberant Spaces

Traditional point-source loudspeaker systems interact with the boundaries of any space in a destructive manner, resulting in over-excitation of the acoustic space, multiple reflections from walls, ceilings, and floors, and overall poor audio performance.

Tectonic speakers do not interact in a destructive manner with boundaries and do not reflect their audio energy in a way that can be perceived as ‘slap-back’ from hard surfaces. Room reverberations and echoes simply disappear.

Little or No Acoustic Treatment Needed

The most common problem facing a house of worship is managing the acoustics of their space. Be it a stone chapel or full cathedral, modern glass design or re-purposed venue, acoustic properties of the space are the deciding factor of whether any speaker system will work well and sound good.

Room problems are usually managed by employing highly-engineered line array systems. Many of these systems also require complex Digital System Processing for ‘beam steering’ etc. Extensive and expensive acoustical room treatment may also be employed.

A Tectonic system’s lack of interaction with problematic acoustic spaces largely or completely eliminates the need for complex digitally controlled systems and the cost of additional room treatments!

Superior Intelligibility

Traditional cone and compression driver devices used in most speaker systems can and do produce significant odd-order harmonic distortion. It’s a byproduct of how they work. Tectonic DMLs distortion levels are nearly immeasurable. In addition, DMLs have no crossover electronics in the critical voice and musical instruments range of ~ 90Hz to 6KHz, which can induce additional time and phase distortion.

Very low distortion and no cross-over anomalies, combined with the Tectonic system’s minimal interaction with reverberant spaces, provides a speaker solution that is highly intelligible.

Extremely Wide and Even Coverage

Tectonic flat panel speakers provide an extraordinary 165⁰ x 165⁰ coverage pattern in the critical voice and musical instrument frequency range and 120⁰ horizontal - by 15⁰ vertical per panel in a multiple panel hang.

The Tectonic design is referred to as a ‘Low-Q’ or very wide coverage system, and has been proven to be the best speaker design to cover large and reverberant spaces with consistent audio and superior intelligibility.

Because all frequencies from ~ 90Hz and up are propagated at this wide coverage, nearly every seat can expect to hear a full-frequency experience. Traditional point-source systems, on the other hand, ‘beam’ their frequency ranges in increasingly narrow coverage as the frequency rises. Only those sitting directly in front of the speakers experience full-frequency audio.

Given that Tectonic speakers are diffuse and wide in their coverage, one would not expect the ability to provide a stereo image. On the contrary, Tectonic speakers propagate the essential audio cues – the ‘precedent effect’ - at the same wide coverage pattern in order to provide the psycho-acoustic impulses needed to create the perception of a stereo image in nearly every seat.

Extreme Feedback Resistance

Unlike traditional loudspeaker system components that have few resonant modes and can easily be excited into a state of feedback, Tectonic Plates are resonant at all times and at all frequencies. It is extremely hard to find a single resonant frequency and harmonic series to excite a Tectonic Plate into a feedback state.

With this superior resistance to feedback, speaker and microphone placements are far less critical and far more flexible.

Architecturally Friendly

The unique technology of Tectonic speakers is reflected in its form factor. By utilizing our flat panel design and high-frequency ribbons, the Tectonic panel is only three inches thick.

Tectonic panels are available in standard powder-coat colors of black or RAL 9010 architectural white. Additional RAL powder-coat color finishes can be provided to match nearly any space and are available on request at extra cost.

Tectonic also provides acoustically transparent fabric covers that can be tonally matched to any Pantone™ color and/or printed with high-resolution graphics to match backgrounds or provided graphics.

VESA™ Mount Compatible

Tectonic speakers are VESA Mount compatible for discrete and flexible mounting solutions. We support the 400mm x 400mm standard for all load-rated commercially available hardware or custom solutions.

Portable Applications

The VESA Mount capabilities also allow for Tectonic systems to be portable. Rolling floor stands move from sanctuary to youth room to gym to outdoors. High-fidelity sound is available wherever and whenever it is required.

No-impact Demos

Tectonic speakers can be demonstrated on demand with no impact to a worship space. With the extremely wide coverage and lack of room interaction, a Tectonic system design does not have to be highly engineered to solve for acoustic challenges.

Tectonic speakers can be placed at approximately 95% of the finished location(s) to prove their performance. Results are real-time, versus predictive print-outs from speaker system modeling programs.
