Quarta Evoluzione (piano black)

After three years of existence, our unique Quarta has undergone a slight upgrade to the Evoluzione version. In the spirit of classic models with this name, we have slightly improved the frequency response and overall sound quality, especially by adjusting the parameters and components of the frequency crossover, but also a more sophisticated system of internal damping, which makes the music blooms even easier and more natural than before. However, we have not forgotten the beauty for the eye, which is why all Evoluzione models are delivered at no extra charge in a deep glossy lacquer.

Quarta (“the fourth note”) is the top model of our Classic Series, it´s standmounter with reasonable footprint, but with uncompromise sound quality, that has no competition in this price tag.

Stands sold separately.
