Welcome to the power of choice. The Duo Grosso is the larger version of the Duo Omega, featuring the same phenomenal spherical horn assembly combined with the significantly more powerful SUB231 subwoofer module. Born of the same heart as the Duo Omega but with a different spirit. Darker. Sportier. Tauter.
By utilizing two powerfull 12 inch drivers, the dynamic headroom of the bass has been practically doubled, compared to the Duo Omega. Exclusive neodymium magnets are used for increased magnetic force and reduced driver displacement.
The engine to push the twin drivers is the massive PA106 power block. This active module incorporates a 2 x 250 watt power amplifier with an astonishing 560VA toroidal transformer and a plentiful supply of 120.000 µF, giving an impression of effortlessness, a sense that endless reserves of power remain.
Great speakers must handle superbly. They should respond quickly and predictably to the music signal; they should be nimble and agile. Achieving full control to overcome the inertia of the driver mass, that is the starting point for such agility. And that´s where the PA106 power block takes full responsibility, taking advantage of Avantgarde´s genuine adaptive motional feedback circuitry. These ultrafast analogue electronics compensate for signal deviations induced by the circuit and drivers in real–time. At a glimpse of a second, insuring that the bass response is clean, profound and dynamic.
At Avantgarde Acoustic™, this precise control is very much in the foreground of the listening experience. It is particularly appreciated during day to day listening where the system develops its full bass extension. This translates to an immediate sensation of power and richness even when idling at low volumes – a landmark characteristic of every Avantgarde.
The active input stage provides analogue controls for bass volume, crossover frequency and subsonic filtering. Operated by precision knobs fashioned from solid, turned aluminium.
The Duo Grosso – with its significantly bigger subwoofer module – melds the smoothness and finesse of the Duo Omega with the dynamic, effortlessness and power of the twin 12 inch driver engine. It is fluent and composed, capable of delivering both, refined immersion into classical sounds and thrillingly dynamic rock and roll. A superspeaker for an exquisite and mindblowing music experience.
