Italy's most experienced Loudspeaker Manufacturer

Dual- cabinets: Solid Walnut, sourced from sustainable Italian forests, jointed for structural rigidity provides Orthotropic properties (low loss).HDF (high density fibreboard) or Corian® (man made stone) provides isotropic properties (high friction losses). They combine in a beautiful, tactile cabinet engineered to damp vibrations from the transducer.

Longevity*: HD transducers including Rohacell drivers®, Non-Ferrofluid tweeters, Neodymium magnets, Full Apex cones®, etc. ensure premium results and years of reliable service.

Predictable Performance (PP): Chario install their bass and ports at the bottom of the cabinet because the distance betwwen the floor and the loudspeaker are always known, regardless of room type. Secondly, Bass and tweeters are thus at their maximum distance, apart from each other, which is desirable for the transmission of large bass sound-waves without disrupting fine treble detail. 

3D soundscape: PP ensures direct sounds arive at the listeners ear first, uninterupted by room reverberation. This ensures a large 3D-holographic image. The other parameters combine to produce a rich sound-colour-palatte, like the famous Italian luthier, for which Chario are well known for.
