Serendipity

Masterpiece

The flagship of the Academy Series is the grand culmination of the extensive research and development undertaken by Chario Loudspeakers since was founded in 1975. Here are some of the concepts, structures, and principles that have brought us worldwide acclaim: NRS 2π sr / Hyper Exponential Hourglass / Reversed Vertical Array / Silversoft Dome / Rohacell® / Full Apex™ / Polyring / Neodymium / Overlapping Points / WMT™ Alignment / SoundCap®

HIDDEN PARTS

Composite materials demonstrate isotropic behavior, dispersing energy in every direction within its fibers. Solid wood however, used in jointed slats with dovetail joints, is the best solution in attaining structural rigidity. Deploying natural wood panels of wood fiber coupled on orthogonal planes, allows us to utilize the best characteristics of both materials. The Serendipity endoskeleton has the task of damping the mechanical vibrations induced by the woofer, confining these within the cabinet.

HOURGLASS DUCT

The pressure that pushes the air inside the reflex duct is extremely high. Consider the analogy of hydraulic lines that push water upward. As the salt loses fluid pressure, the jets lose speed and weaken. Hence the goal must be to retain the optimal pressure within the reflex duct to ensure a consistent strength in the acoustic wave, while avoiding the audible noise past pressure speeds of 130km/h. The photograph above demonstrates the reflex duct section with the Hourglass hyper-exponential, in a two-dimensional Serendipity.

Nature on It

Our finishes are completely natural, and also the varnishes used are water-based and non-toxic. The production process ensures full environmental sustainability Using only materials from Italy, our attention to the treatment, processing, and final fit and finish creates a speaker cabinet of extraordinary rigidity and visual beauty. Our wood treatment alone requires six months, and six different production departments to ensure quality never falls short of perfection. Coupled with our proprietary driver technologies and arrangements, all Chario Loudspeakers are hand assembled in Italy, in Chario’s own production facilities.
