ÀSTERA
REFERENCE COLLECTION
INNOVATIVE DESIGN
The shape of this multi-faceted cabinet makes it possible to obtain circular sound emission from the drivers.
The speaker recedes from the soundstage and the listener just hears the music, with all the features of a live event.
The numerically-controlled techniques used for the curves on the front and back panels of the cabinet make acoustic dispersion around the speaker even more effective. Three-dimensionality, detail and the realism of the soundstage where the listener is immersed all improve.
FOCUSING ON THE MUSIC
The multi-faceted shape of the Ástera model has been designed to obtain optimal acoustic dispersion and enable the circular emission of the sound waves around the speaker, achieving as ideal a point source as possible
QUALITY MATERIAL
Select SEAS-manufactured drivers, silk dome tweeters, paper cone woofers and cabinets made of aged wood achieve the best sound reproduction rich with harmonics, perceived as balanced musicality by the human ear.
THE COMPONENTS
Crossovers and transducers in each Diapason design are the result of advanced technological research and are tested individually and in combination, with tolerance levels of 1% to obtain the best performance. The tweeter has a soft silk 29-mm dome and a magnetic Hexadym system that incorporates a dual damping and ventilation system.
The woofer has a Nextel-coated paper cone and metal basket. Crossover circuits are wired directly using oxygen-free copper and silver Van den Hul cables, avoiding the unwanted effects of printed circuits.
DEDICATED STAND
The 4/U support stand has 4 metal legs combined with solid wood side panels that integrate with the speaker aesthetics and make the structure more rigid, ensuring optimal speaker performance.
Stands are 75 cm in height, with 4-cm spikes under the base to lift them off flooring, carpets or rugs.
AUDIO EXCELLENCE AWARD WINNER 2013
“The prized result produced from solid wood using expertise resulting from experience and Italian tradition in constructing speakers”.
TECHNICAL SPECIFICATIONS
Type: Bookshelf/Standmount 2 way, 2 speakers
Acoustical Loading: Bass-Reflex, Rear emission port
Cabinet: Solid walnut wood construction. Engraved multifaceted front and rear baffles for optimal diffractions management. Water based natural finish.
Drivers/Internal Wiring:
Tweeter: 29 mm silk soft dome, underhung voice coil ensures low distortion even at low frequencies. Hexadym magnet system based on 6 radially magnetized NdFeB magnet blocks provide efficient ventilation and damping of cavities behind the dome, surround and voice coil.
Mid-woofer: 180mm paper nextel coated con cone for smooth frequency response, CCAW voice coil for low distortion and excellent transient response. Heavy copper rings mounted above and below the T-shaped pole piece reduce non-linear and modulation distortion and increase overload margin. Fe magnet.
