Duo GT G3 - Spherical Horn Speaker System

The Avantgarde Duo GT G3 represents the pinnacle of high-end audio, a two-way spherical horn speaker system with built-in active subwoofers. Available in passive or active configurations, it's easy to upgrade with NatureCap or iTRON Current Drive modules, which connect via a multi-pin connector and are easily swappable. Aesthetic customization options include 12 horn colors, with the option of a matte black or lacquered cabinet finish, and black or anodized copper metal accents.

The Avantgarde G3 spherical horns, designed with advanced mathematical calculations and high-precision modeling tools, ensure controlled directivity, minimizing environmental reflections and reducing acoustic distortions by up to 90%. The co-planar configuration of the drivers ensures perfect time alignment and superior sound reproduction.

The Evolution drivers, developed to work in perfect synergy with the horns, implement advanced technologies such as AirGate for coupling chamber control and Omega Voice Coil for high electrical impedance and improved damping. The Single Frame die-cast steel baskets ensure stability and power, while the suspension and triple-layer Kevlar spherical dome diaphragms reduce resonances.

The 3-inch XT1 tweeter has been completely redesigned with a 200mm horn profile and 176mm throat, offering minimal distortion of 0,32% and an extended frequency response up to 28kHz. The 2-inch XM7 midrange driver operates in a 670mm horn, with a new Soft-Mesh-Compound diaphragm that reduces resonances and a very high efficiency (107dB/W) magnetic motor. The AirGate passive crossover filters high frequencies without electronic components, while the NatureCap circuit with PolarisationPlus stabilises the magnetic field of the capacitors.

The system includes a powered subwoofer with two 12-inch XB12 woofers, oversized motors, and high-grade magnets for a power output of 1000 W RMS. The G3-1000 amplifier integrates an advanced DSP digital crossover with 8-band equalizer, variable low-pass filter, and Ethernet and USB connectivity for management via Avantgarde Control software.

The cabinet, with a minimal design and structured in steel, is finished with Piano High Gloss side panels and legs with adjustable conical tips in die-cast aluminium, which reduce vibrations and improve stability.

About the brand

Avantgarde is a German manufacturer specializing in horn speakers, a technology that guarantees efficiency, dynamics, and natural vocal reproduction. These speakers are ideal for those seeking direct and immersive listening without compromising clarity, and for enthusiasts who want to take advantage of even moderately powered amplifiers thanks to their high sensitivity.

Choosing an Avantgarde speaker depends on your listening space, amplifier power, and preferred music type: compact models like the Colibri C2 and UNO SD G3 are suitable for medium-sized rooms, while the DUO, TRIO, and MEZZO offer greater sound pressure and extended bass, possibly supported by the C18 Subwoofer. In our showroom in Carpi, you can listen to the different models, receive advice on matching them to your system, and evaluate new, guaranteed used, and ex-demo solutions, also taking advantage of Trade-Up options.

Floorstanding or bookshelf speakers: a guide to choosing

Imposing tower or compact bookshelf? It's the question every enthusiast asks at least once, and the answer is never obvious. The choice between floorstanding and bookshelf speakers depends on more than just budget or space...

Anatomy of a Tower: What Makes a Speaker Unique

A floorstanding speaker is built to stand alone, without the need for external supports. Its height—often between 80 and 120 centimeters—allows it to house multiple separate drivers: a tweeter for highs, a midrange driver for midrange, and one or more woofers for bass. This multi-way configuration offers more granular control over different portions of the sound spectrum.
