Magico is proud to introduce the new ACC loudspeaker which pairs perfectly with the incredible A3 to create a seamless front-stage of sound performance. The ACC features a sealed, fully braced aluminum enclosure, beryllium dome tweeter, carbon Nanographene cones, neodymium-based motor systems and our renowned elliptical crossover. A true Magico loudspeaker design offering unparalleled sound performance in its category and price point and above all deserving of the Magico “M” engraving - a mark of our uncompromising drive to push the boundaries of loudspeaker technology. In combination with our tremendously successful A3, newly announced A1 two-way, ACC center channel and the ASUB, all applications for a full Magico home theater are now accessible to a larger audience than ever before.
Aircraft Grade Aluminum Enclosure
The ACC enclosure is constructed using ⅜” thick 6061 T6 aircraft grade aluminum, similarly to the enclosure developed for the Q1 and is available in an elegant brushed, black-anodized aluminum finish. An innovative internal bracing technique along with the most advanced damping materials makes the sealed enclosure incredibly rigid and free of unwanted mechanical resonances. The finished enclosure design of the ACC is evaluated in simulation using the latest FEA software along with physical testing to meet the no-compromise requirements of Magico for optimized enclosure rigidity, stability and to ensure benchmark acoustical standards.
High Frequency Driver
The ACC tweeter follows the A3 with a pure Beryllium-diaphragm tweeter with an optimized 28-mm dome surface which is based on the fundamental design platform and geometry of our reference M-Series tweeter design. 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 6-inch midrange driver, also deployed in the A3, features a Multi-Wall carbon fiber cone with a layer of XG Nanographene, providing an optimal stiffness to weight ratio and an ideal damping factor. The driver frame has 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. An overhung neodymium-based motor system incorporates extra-large magnets to ensure a stabilized magnetic field in the 75-mm pure titanium voice coil. The ACC midrange driver is 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.
Extended low bass frequencies which are incredibly deep and fast result from 7-inch bass drivers (x2) that are found in the A3 which are produced with advanced manufacturing techniques using MultiWall carbon fiber with a layer of XG Nanographene. Powerful neodymium magnets control a 75-mm pure Titanium voice coil that has long throw excursion and produces clean, undistorted sound pressure levels. Individual driver performance and the ACC loudspeaker in its final form are tested and optimized for acoustical, mechanical, electromagnetic, and thermal behaviors using the latest state-of-the-art Finite Element Analysis simulation testing equipment.
