2 x 8 mm Al-Mg Low Dynamic Drivers

[Sub-low & Low]

The 8-mm isobaric dynamic drivers offer powerful output and precision sound. Two 8-mm dynamic drivers handle the low and mid-low frequency ranges, offering tighter, more precise, and better tuned bass thanks to their exquisite design.

Eight Drivers: Two Sets of Four Balanced Armature Drivers

[Mid-low] [Mid] [Mid-high]

It comes with specially selected four mid-low balanced armature (BA) drivers and four mid and mid-high BA drivers with two pairs of dual BA drivers that combine to handle the mid and mid-high frequency range. The carefully selected eight BA drivers work together to create precision mid-range sound and produce warm and emotional male and female vocals.

1 Balanced Armature Super Tweeter

[High & Super High]

Balanced armature (BA) drivers designed with to maximize a sense of space and openness are utilized to create soft, delicate, yet expanded ultra-high-frequency sound that resonate richly in your ears.

5-Way Crossover

The AURA technical configuration is designed with a 1st grade crossover, meticulously manufactured in Germany. All components being well chosen for lowest tolerances possible on the market. AURA is using a 5-way crossover with a particular circuit solution that avoids an excessive load from the tweeter towards the source (amplifier), thus reducing distortion and extending the reproduction of high frequencies. Internal wiring is made with premium silver plated copper alloy wire for highest performance.

Isobaric configuration with two dynamic drivers

Two 8mm dynamic drivers are placed facing each other in an isobaric configuration. As two drivers are placed facing each other and the sound is output from exactly between them, the constructive interference is maximized, effectively doubling the output volume. This, in turn, removes any phasing issues that may raise from the length difference between the sound tubes, reducing THD. This design makes the low-frequency sound created by the dynamic drivers more accurate, solid, and vibrant.

Chamber

The "special chamber" have a precise internal volume that has been calculated to get the best compromise between driver speedness and musicality. The two DD Drivers are strictly matched to reduce any possible phase incoherence which could lead to inaccurate transient reproduction.

Mesh

AURA's open-structure design features a vacuum metal mesh that gleams elegantly on top. This special aluminum acoustic mesh circulates air from the dynamic driver to control the powerful resonating force, protecting internal components from external influences.

The Micro Groove Design Faceplate

The Micro Groove Design is applied with surface treatment for milling process. Grooves are dug along the grain of the raw material to create a unique design, before the product is moved to a precision-tailored jig for laser engraving. This process is not just a standard laser process but a special laser process that eliminates parts of the raw material to engrave letters 0.5 mm deep while adding depth to the engravings. Next, the component is treated with oil to prevent oxidation, packaged, anodized, and given a custom dark bronze color.

Precision-Milled Aluminum Shell

Unlike the faceplate, the shell is oil-sealed and then handed to the polishing master. The faceplate is engraved with an esthetic design element, and the surfaces of shells are polished through a special sand-blast refinement process. Otherwise, marks will be left from the tools used, so each shell is polished like mirror by hand. Then, after sand-blasting and anodizing, the shell is ready to be given Vision Ears' custom warm gray color. The AURA shell is the result of thousands of hours of work, including cutting diamonds out of rough rocks with carefully selected materials, precision processes, and specialized tools.
