Precision Meets Emotion: AURA
AURA uses the best-quality drivers, materials, and meticulous design for unparalleled sound. A total of 11 drivers enable overwhelming precision and offer perfect response and balance through the 5-way crossover. The delicate shell and mesh structure made from high-quality materials ensures that all components of AURA combine to create rich and natural sound. Expertly crafted in Germany, AURA blends innovation, sophisticated styling and cutting-edge technology to create a listening experience like no other.
"It is extremely difficult for 11 driver units to clearly express each frequency range while maintaining a perfect balance. AURA delicately tunes the 5 frequency ranges divided according to their unit characteristics based on the 5-way crossover method to achieve a perfect balance. In particular, with its ultra-high frequencies and balanced sound, it can even perfectly recreate hi-fi audio like Astell&Kern's SP3000."

Custom Designed 11 Drivers
(x2) 8mm Al-Mg Low Dynamic Drivers [Lows]
The 8-mm isobaric dynamic drivers offer powerful output and precision sound. Two 8mm dynamic drivers handle the low and mid-low frequency ranges, offering tighter, more precise and better-tuned bass.
8 Balanced Armature Drivers: (x2) Sets of four [Mids]
AURA comes with 4 specially selected mid-low balanced armature (BA) drivers and 4 mid and mid-high BA drivers (a pair of dual BA drivers) that combine to handle the mid and mid-high frequency range. The carefully selected 8 BA drivers work together to create precision mid-range sound, producing warm and emotional vocals.
1 Balanced Armature Super Tweeter [Highs]
A BA driver designed to maximize a sense of space and openness are utilized to create soft, delicate, yet expanded ultra-high-frequency sounds that resonate richly in your ears.
Ultra-Precision Technology
5-Way Crossover
AURA is using a 5-way crossover with circuit solution that avoids excessive load from the tweeter towards the source (amp.) This reduces distortion and extends reproduction of high frequencies. Internal wiring is made with premium silver plated copper alloy.
Isobaric configuration with 2 Dynamic Drivers
Two 8mm dynamic drivers are placed facing each other in an isobaric configuration, maximizing the compositional interference, doubling output volume, removing any phasing issues from the sound tubes, and reducing THD.
Chamber
The chamber has a precise internal volume calculated to get the best compromise between driver speed and musicality. The 2 DD drivers are strictly matched to reduce possible phase incoherence.
Mesh
AURA's open-structure design features a gleaming vacuum aluminum acoustic mesh on top which circulates air from the DD to control resonating force, protecting internal components from external influences.
