Virtuoso by Gravelli Bespoke Audio

Gravelli introduces the newest development in high end audio section – a pair of fully active speakers with powerful, balanced and truthful sound.‎ A unique enclosure made of concrete, and high technology and crafts have merged to create a true music experience.‎

Three years of development have packed an ultimate sound performance into two minimalist speakers.‎ The sound of Virtuoso is comparable to much larger and complicated high end audio systems, but thanks to its design it performs perfectly in various spaces including smaller city-centre interiors.‎

Every important component, such as amplifiers, D/A converters or sound card, is already inside the speakers.‎ You just put them on a stand, connect your device, press play and listen.‎

The color of concrete and the front baffle material are customizable.‎ You choose the combination that fits the most to your interior.‎  

Every speaker is handcrafted in Gravelli Prague manufactory where all the details get a personal approach and hand care.‎
