ZERO iTronINTRO/CONCEPT
More integrated, more compact, simpler - and yet a true horn loudspeaker. The ZERO iTRON realises a dream that we have shared with many friends of our horn loudspeaker manufacturer for over twenty years. For as much as we are fascinated, moved and overwhelmed by our larger transducers, there has always been a desire for a more compact horn loudspeaker that would make the unrivalled Avantgarde Acoustic experience accessible to a wider group of sound enthusiasts.
The ZERO series opens up this new path with its revolutionary design, minimalist style, effortless installation and fully integrated amplifier and processor technology.
The ZERO iTRON is a 3-way active loudspeaker in a 2 x 10 watt iTRON current amplifier and 1 x 400 watt Class D power amplifier configuration. The strict division into 3 ranges prevents bass signals from affecting midrange and treble reproduction and vice-versa. The EvolutionAA XM1 is a 127 mm midrange horn
driver optimized for large, linear excursion.
Its new “SoftMesh–Compound” membrane uses a stable grid carcass as its structural foundation. The microscopic apertures of the grid are sealed with a proprietary synthetic elastomer coating. Combining a stable grid structure with a flexible lining
effectively reduces partial resonances of the dome itself and absorbs distortions. The tweeter of the ZERO iTRON features an annular diaphragm which extends its frequency range up to 22,000 Hz with 107 dB sensitivity, ensuring greater clarity, focus, and harmonic resolution, a fuller and more natural sound.
The ZERO iTRON is combined with a powerful subwoofer module, utilizing a redesigned powerful 12”-driver in a bass reflex configuration. The bass amplifier of the ZERO iTRON has 400 watts and is equipped with an advanced digital sound processor. The new user interface allows for a simple adjustment of the sound to individual preferences and seamless system integration in different rooms.

Spherical horns.
THE ROYAL ROAD TO SUPERIOR SOUND –
PERFECTED BY AVANTGARDE.
More than 30 years ago, we transformed a funda-
mental natural principle into a unique product
portfolio, using precise mathematical algorithms.
Superior horn technology using the most precisely
calculated spherical wave horns ever made. Form
follows function. Natural efficiency generates
engineering and artistic elegance.
SETTING LIMITS TO OVERCOME LIMITATIONS.
Instead of uncontrolled radiation in all directions,
our spherical horns emit sound waves with
perfectly controlled directivity. This acts to both
concentrate the sound – improving perceived
efficiency, presence, and energy – and reduce
unwanted sidewall reflections that muddle and
distort the music.
LESS LOSS, MORE MUSIC.
A horn mounted on the front of the speaker is the
most effective way to increase the efficiency of the
system. The moving parts of the loudspeaker –
voice coil and diaphragm – can be made much
more compact. Smaller moving parts mean less weight and greater mechanical control.
This reduced size and weight of the moving parts results in a significant reduction in moment of
inertia, increasing the sensitivity and responsiveness of the system. The diaphragm in a horn loud speaker not only accelerates much faster, but also comes to rest more quickly, if and when the audio
signal demands it. The reduction in diaphragm area also increases the mechanical stability of the assembly. The improved mechanical behavior of the diaphragm combined with its smaller excursion significantly reduces distortion.
‘SURGICAL’-QUALITY HORNS.
The driver is one-half of the equation. The spherical horn is the other. Its profile must be calculated
with micro-millimetre accuracy so that the sound waves do not ripple or refract within the horn,
causing reflections and thus interference and distortion. Avantgarde’s spherical horns are not just incredibly complex in design and development, their manufacturing requires incredible accuracy and consistency, involving massive aluminium tooling and the sort of clean surfaces normally only found in operating theatres.
SQUARING THE CIRCLE.
Have you ever seen a trumpet with a square mouth? To take full advantage of the natural laws
that govern horn performance, the horn itself must be circular. The sound waves thus propagate linearly from the circular diaphragm of the driver through the hornand out into the room, completely free of diffraction or interference.
SCIENTIFICALLY PROVEN.
We have subjected our horn speakers to the most exacting, independent scientific testing. The results from university laboratory tests even impressed the researchers!
• 8 x greater dynamic range
• 90% less distortion
• 10 x more resolution
What do those results mean in musical terms? This range from the softest sound to the loudest is 8 x greater with an Avantgarde Acoustic speaker. At the same time, due to the much lower distortion and higher resolution, our horn systems can clearly and accurately reproduce musical sounds and textures, the tiny details that bring recordings to life, that are finer by a factor of ten than with conventional loudspeakers in a box design. A full-fledged spherical wave horn system, the ZERO iTRON has all of the tonal advantages provided by the horn technology
MID/HIGH
1: UNRESTRAINED HIGHFREQUENCIES.
iTRON has tremendous high-frequency resolution because it compensates perfectly for the
increasing inductance in the tweeter. Combined with the extended frequency response of the new
G3 super tweeters, this means fabulously delicate reproduction right up to the highest frequencies,
without the level drop otherwise inherent in other systems. The system easily covers the 250 Hz to 4,000 Hz frequency.
107 dB
2: The recessed XT2 Super tweeter features a ring shaped diaphragm that extends the frequency range up to 22,000 Hz with 107 dB sensitivity ensuring greater clarity, focus and harmonic resolution as well as a fuller more natural sound and it is all driven by the Itron voltage/current converter technology.

A 12 Volt switching voltage input allows the ZERO iTRON to be powered on remotely. The signal take-off is not only at high impedance but is also balanced and transformer-coupled. This floats the circuit ground, avoiding hum loops.

INNOVATIVE.
Innovation that revolutionizes sound.
The amplifier that is not an amplifier.
iTRON is a innovative electronic circuit from
Avantgarde that, for the first time ever, allows
perfect control of the driver’s diaphragm,
achieving an incredibly detailed, pristine, and crystal-clear sound. The difference to conventional
amplifiers is so great that we call it our game-
changer technology.
Filter
The purpose of a crossover in any multi-way loudspeaker is to prevent the same frequencies from being produced by different drivers simultaneously. If that happens, the tones can overlap, resonate, or cancel each other out. This interfer-
ence must be avoided at all costs for credible, high-quality musical reproduction – reproduced music that sounds like life. The ZERO iTRON uses the most effective method of frequency division using active filtering technology, dividing the frequency spectrum before the built-in amplifiers.
SPHERICOWCUT TECHNOLOGY.
Each of our spherical horns can only reproduce low tones down to a certain, clearly defined
The Crossover
frequency. If the wavelength of the notes
becomes larger than the dimensions of the horn, those notes cannot properly propagate and are automatically filtered. Through careful calculation and without any additional componentry, Avantgarde Acoustic horn drivers use SphericLowCut
technology to achieve perfect, perfectly natural low-frequency roll-off, the most efficient possible filter, based entirely on physical laws and devoid of any artificial artefacts.
AIRGATE TECHNOLOGY.
With AirGate used for the midrange, we have developed an innovative passive technology that filters high frequencies without placing a single component in the signal path. Unique, innovative, and without the typical, negative side effects.
