The A3’s massive sealed-enclosure is, like all Magicos, a tour-de-force of engineering. The enclosure is made entirely from 6061 T6 aircraft grade aluminium, identical materially to the enclosure developed for the Q Series. This braced, complex internal structure is finished externally with an elegant brushed anodized “skin”.

Extended high frequencies are provided by a newly designed Magico pure beryllium-diaphragm tweeter with an optimized 28-mm dome surface based on the fundamental design platform and geometry of the M-Project tweeter. The customized neodymium motor system is encased in an improved back chamber with our latest generation damping materials that facilitate ultra-low distortion, higher power handling, massive dynamic capabilities and extended linear voice coil movement.

The newly developed 6-inch midrange employs a Multi-Wall carbon fiber cone with a layer of XG Nanographene, providing optimal stiffness to weight ratios and an ideal damping factor. Overhung neodymium based motor systems incorporate extra-large magnets to ensure a stabilized magnetic field in the 75-mm pure titanium voice coils of both the midrange and bass drivers.

Dual 7-inch woofers incorporate a version of the new Gen 8 Magico Nano-Tec cone. The same properties and materials that allow for the proper combination of stiffness, mass and damping are carried through to the lowest frequencies. The chassis has also been simulated and tested for the optimal combination of stiffness and damping. Minimum acoustical impact is achieved through reducing vibration modes while maximizing air flow. A new overhung neodymium (N48) based motor system anchors the low frequency reproducers to accomplish a super stabilized magnetic field. A pure Titanium, 75mm voice coils are consistent with the technology utilised through the midrange. 

The A3 Midrange and Low frequency drivers were optimized for minimal music related distortions in its band pass, in both the frequency and time domains using latest state of the art FEA simulation of acoustical, mechanical, electromagnetic and thermal behavior. All of this is now being done on a single platform, allowing Magico to take the next step in performance optimization.

All four drivers in the A3 are acoustically integrated using Magico’s proprietary Elliptical Symmetry Crossover topology that utilizes state-of-the-art components from Mundorf of Germany. The 3-way network features a 24db per octave Linkwitz-Riley filter that maximizes frequency bandwidth while preserving phase linearity and minimising intermodulation distortion.

The A3 enclosure is best considered as a simplified Q Series design, with the same materials, the same craftsmanship, and the same attention to design and build detail.
