Open electrostatic architecture of Lirogon Origin

TECHNOLOGY

Less between you
and the event.

Lirogon technology is guided by subtraction: less moving mass, fewer transitions, lower stored energy and no conventional electrical crossover network.

01

LIROSTAT

Every panel receives the complete musical signal. Mechanical tuning defines what it radiates; the signal determines how many modal regions appear at a given instant.

LIROSTAT uses a family of continuous, ultra-light diaphragms rather than a fixed array of cone drivers. Fundamental and higher-order resonances form changing radiating zones across each surface. During complex passages, more than 80 effective acoustic regions may act simultaneously. They are not permanent drivers: they emerge, overlap and disappear as signal-dependent modes across mechanically tuned panels.

02

Crossover-free precision

The audio signal is not split by conventional RLC filters. Frequency shaping happens mechanically and through transformer-based distribution.

Origin avoids the conventional network of coils, capacitors and resistors placed between amplifier and drivers. The working ranges of the membrane zones are defined by their physical properties and by the way the signal is distributed through dedicated transformers. Removing a traditional crossover reduces phase rotation, stored energy and the sense of separate sources speaking at once.

03

ZUKA sound correction

ZUKA adjusts selected parts of tonal balance mechanically. No additional electronics enter the signal path.

The patented ZUKA system provides a precise mechanical method of refining the loudspeaker’s behaviour for a particular room and listening position. It allows selected aspects of tonal balance to be addressed while preserving the directness of the electrical path. Setup becomes a controlled acoustic process, not an electronic overlay added after the fact.

04 · LIROSTAT ARCHITECTURE

One signal.
An acoustic surface in motion.

Every panel receives the complete musical signal. There is no conventional crossover deciding which driver plays.

Geometry, tension and individual mechanical tuning determine how strongly each diaphragm responds across the spectrum. The result is an acoustic surface that reorganises itself continuously with the music.

01

Complete signal

Every panel receives the entire musical waveform; no electrical crossover decides when it begins or ends.

Origin does not divide music into separate electrical bands assigned to a woofer, midrange and tweeter. The complete waveform reaches every electrostatic panel. What each surface contributes is governed by its physical acoustic behaviour, so adjacent ranges meet without a conventional network of coils, capacitors and resistors handing the signal from one driver to another.

02

Mechanical tuning

Panel geometry, tension and individual calibration define its acoustic working range.

Dimensions, diaphragm tension and the mechanical construction of each panel establish its fundamental and higher-order resonances. Every panel is then tuned by hand for a defined part of the spectrum. Their operating ranges overlap and integrate acoustically, creating a continuous response from bass to treble while using the same ultra-light diaphragm technology throughout.

03

Dynamic modes

Radiating regions emerge, overlap and change continuously with the musical signal.

A diaphragm does not behave as one fixed piston. As frequency, level and musical complexity change, different resonant patterns form across its surface. Individual areas begin to radiate, merge with neighbouring regions and disappear again. The active acoustic geometry therefore reorganises continuously in direct response to the music.

04

More than 80 acoustic modes

During complex passages, over 80 effective radiating regions may act at once.

An intuitive comparison would be a conventional loudspeaker able to bring dozens of dynamic drivers into operation at the same moment. LIROSTAT can create more than 80 effective radiating regions during a complex passage, but these are not separate physical transducers. They are temporary acoustic modes appearing across continuous membranes, without individual voice coils or crossover sections.

05 · ZUKA

Pure signal.
Mechanical control.

ZUKA is Lirogon’s proprietary, patented mechanical sound-correction technology.

Turning the control mechanically moves two stators closer together or farther apart around the diaphragm. The resulting change in electrostatic geometry alters the panel’s acoustic output, providing continuous adjustment of selected high-frequency bands within a range of ±5 dB — without processing the audio signal.

01

Pure signal path

Level is controlled by changing transducer geometry — not by DSP, EQ or an electronic filter.

ZUKA acts inside the electrostatic transducer itself. A precision manual mechanism changes the distance between the two stators, moving them closer to or farther from the diaphragm and altering the strength of their electrostatic interaction. Acoustic output changes mechanically, while the signal from amplifier to diaphragm remains untouched by an additional correction circuit.

02

Room integration

High and ultra-high-frequency output can be adjusted by up to ±5 dB for the room and listener.

Room absorption, loudspeaker placement, listening distance and individual hearing all influence perceived tonal balance. ZUKA provides direct manual control over selected high and ultra-high-frequency panels, allowing their contribution to be raised or reduced continuously within a ±5 dB range. The adjustment can refine brilliance, presence and spatial perspective without processing the rest of the spectrum.

03

Phase preserved

Mechanical correction adds no processing latency or filter-induced phase rotation.

Electronic equalisation changes amplitude through frequency-dependent circuits or algorithms, which can add phase rotation, group delay or processing latency. ZUKA makes a static physical adjustment to the stator spacing instead. It therefore introduces no additional electronic correction stage and preserves the timing relationships of Origin’s direct, crossover-free signal architecture.
