MAGICO / A5

The 9” bass drivers in the A5 feature a newly enhanced version of Magico’s Graphene Nano-Tech cones. Graphene, a hexagonal lattice of carbon and in relation to its thickness, it is about 100 times stronger than the strongest high-carbon steel. The new cone design combines Graphene layered carbon fiber with advanced new core materials to achieve the highest possible stiffness to weight ratio. Extensive computer simulation and prototype testing allows engineering to create the driver chassis frame with an ideal combination of stiffness and damping, with minimal acoustical contribution and maximized airflow. The new bass driver incorporates oversized components including a 5-inch pure Titanium voice coil and huge copper cap with ½” of linear excursion. The super-stabilized magnetic field enables the A5 to output thundering levels of bass, producing 115 dB SPL (@ 50 Hz, 1 meter), while maintaining very low distortion and inductance below 0.18 mH. Finite Element Analysis (FEA) provides Magico engineers a single platform to assess acoustical, mechanical, electromagnetic and thermal properties. This meticulous testing helps minimize distortions in the frequency and time domains.

The new 5-inch full-cone midrange driver enables wider dispersion and greater midrange transparency. Like the bass driver, the midrange also incorporates an advanced Graphene carbon fiber sandwich cone. A new foam surround helps achieve ideal cone/surround integration, faster settling time and impressively low distortion. The all-new motor system features a pure Titanium voice coil that operates in a super-stabilized magnetic field with a pure copper pole cap to minimize eddy currents and maximize efficiency. This latest midrange driver design truly sets a new benchmark of measured performance. A dedicated sub-enclosure houses the midrange driver, protecting it from the extensive back wave energy of the bass drivers.

The tweeter dome is based on the fundamental design platform and geometry of the M-Series tweeters and shared with the other A-Series models; the tweeter incorporates a pure beryllium-diaphragm with an optimized 28-mm dome. Magico encases the customized neodymium motor system in an engineered back chamber with the company’s most advanced damping materials. This enables ultra-low distortion, high power handling, massive dynamic capabilities and extended linear voice coil movement.

The A5 will be the first product in the world to offer Mundorf’s new M-Resist Ultra foil resistors. Now perfected after years of development, the new resistors deliver greater power handling, transparency and liquidity. The Elliptical Symmetry Crossover topology acoustically integrates all five drivers using a full complement of state-of-the-art components from Mundorf EB Gmbh of Cologne, Germany. The 3-way network features a 24 dB per octave Linkwitz-Riley filter that maximizes frequency bandwidth while preserving phase linearity and minimizing intermodulation distortion.
