Avantgarde ZERO iTRON is an active floorstanding loudspeaker with 3-way sound. It has two 10W amplifiers and one 400W Class D subwoofer amplifier.
The low frequency range of the speakers is serviced by a single 10-inch XB10 driver with a 152 mm diameter sound coil. The diffuser is made of a composite material based on long-fiber paper and carbon fiber. The bass amp has an output power of 600 watts, active filters controlled by the processor, and a new G3 user interface for programming.
The Avantgarde Acoustic Duo Mezzo XD is a horn–type speaker system with an active woofer section. It is a compact semi-active High-end speaker system with active crossover (DSP). The speakers have a horn acoustic design.
The model uses a new generation of EvolutionAA drivers for greater dynamics and clearer sound, and an innovative XT3 tweeter unit with a new long-range horn and an extended frequency range of a supratwiter with record-low distortion values.
The Avantgarde Acoustic DUO GT horn speakers are available in a "passive" version with active bass (1 kW at LF) and a fully active version - with a digital crossover and amplification iTRON amplification. In the first case, you will get 107 dB of sensitivity!
