Apertura Adamante hi-end loudspeakers
The Apertura Adamante is a high-end floorstanding loudspeaker derived from the flagship Enigma, combining a compact enclosure with a professional ribbon tweeter, dual custom 18 cm Isotactic Matrix drivers and DRIM crossover technology for exceptional realism, precision and musical refinement.
Enigma Technology in a More Compact Format
Derived from the experience gained with Enigma, the Adamante was designed to deliver performance as close as possible to the flagship model while remaining easier to integrate into modern living spaces. It combines compact proportions with sophisticated engineering and exceptional musical realism.
Professional Ribbon Tweeter
A professional ribbon tweeter with an aluminium/polymer sandwich diaphragm provides outstanding linearity and extremely low distortion. Its radiating surface is twice the size of the ribbon used in the Onira and four times larger than a conventional dome tweeter, allowing an unusually low crossover frequency of 1.8 kHz while preserving the speed, refinement and transparency of ribbon technology.
Custom 18 cm Isotactic Matrix Drivers
Adamante employs two heavily modified 18 cm Isotactic Matrix bass/midrange drivers. Improvements to the motor system, vibration damping and magnetic field management reduce distortion while maintaining excellent linearity. The hybrid loading system allows both drivers to operate as a truly correlated acoustic source.
DRIM Crossover Architecture
The proprietary DRIM crossover combines successive 6 dB, 12 dB and 24 dB slopes to optimise driver integration, minimise intermodulation and preserve accurate phase relationships. Separate crossover boards, hand assembly and premium components ensure exceptional transparency.
Advanced Cabinet Construction
The enclosure features curved side panels, pressure-moulded laminated MDF, an internal structural frame, four different damping materials and a hybrid acoustic-line/bass-reflex loading system. A central mechanical grounding cone positioned beneath the cabinet further reduces unwanted vibrations.
Designed for Pure Musical Enjoyment
Adamante retains the musical qualities of the Onira while offering greater bass authority, increased precision and higher refinement. Designed to partner with the finest audio electronics, it faithfully reproduces recordings with natural tonal balance and an expansive three-dimensional soundstage.
