The Academy Series flagship is the refined expression of all the research typical of Chario Loudspeakers development since 1975. It would take too long to describe the structure and the working principles so we prefer to sum up the through concepts that have made it famous worldwide:

• NRS 2π sr
• Hyper Exponential Hourglass
• Reversed Vertical Array
• Silversoft Dome
• Rohacell®
• Full Apex™
• Polyring
• Neodymium
• Overlapping Points
• WMT™ Alignment
• SoundCap®

Ecological natively , the composite material shows an isotropic behavior , dispersing energy in every direction within the fibers . The solid wood instead , used in jointed slats with dovetail joints , is the best solution in terms of structural rigidity . Combining the natural wood panels of wood fiber, coupled on orthogonal planes , we reach the goal of combining the best characteristics of both materials. Indeed, the Serendipity endoskeleton has the task to damp the mechanical vibrations induced by the woofer and to confine them within the cabinet . In the photo are identified plans tensors , the reflex port and the castle that houses the two subwoofer 320 mm in isobaric configuration proprietary NRS .
Vlady Dalla Fontana is not speaking of the magic that the natural wood emanates from view, it is normal for him and takes it for granted that you know it ...
There is even talk of the magic that emanates natural wood to the touch, it is normal for him and takes it for granted that you know it ...
Vlady Dalla Fontana will only tell you that providing the correct drawings CAD / CAM can be obtained , starting from a plank of wood 10 cm thick , the fianchetto subwoofer Serendipity ...
Because the side panel has a sinuous form so as to shine with their own light is destined to remain a secret that ...

2Subwoofer 320 mm Natural Fibres - 2 Waves Surround HF motor

  93dB SPL normalized to 1 m / 2.83 Vrms / de-correlated L/R pink noise in 
ITU-R BS 1116-1 compliant listening room
23Hz @ -3 dB referred to C4 WETS
240/ 500 / 1250 / 1850 Hz ( See Plot )
Modulus 4 Ω (min 3.0) Argument ±36°
1610 x 400 x 580 mm (H x W x D)
100 kg
Solid walnut or solid cherry and hdf. The structure comprises two cabinets: the lower contains two subwoofers; the upper contains two woofers, one midrange and one tweeter. The two wood cases are separated by four cylindrical proprietary-engineered elastometric puffers acting as vibration decouplers to dissipate mechanical energy by orthogonal elongation

Speakers should be titled inward facing the listener
Optimum speaker-listener distance > 3.5 m
A carpeted floor in front of the speakers is recommended
Should be at least 1m away from the speaker front baffle


400W / 4 Ω Average Power

Run the cable from the power amplifier to the lower terminals of the subwoofer binding post, then connect upper terminals to the mid-high unit binding post by means of the short cable with banana plug provided with the speakers


200W / 4 Ω Average Power

Run the cable from the power amplifier to the lower terminals of the subwoofer binding post leaving upper ones idle. Repeat to connect the power amplifier to the mid-high unit binding post (two terminals only)
