The S3 Mk II nestles in between the S1 Mk II and S5 Mk II and features all of the advanced design elements of the S-Series Mk II models, including a new 9-inch bass driver with the lowest measured distortion born from the design and engineering theories applied to the limited-edition, 10th Anniversary M-Project.

Superlative high frequencies are provided by a 1-inch Magico diamond-coated beryllium-diaphragm tweeter that offers matching sensitivity, wide dispersion, and increased power handling over its predecessor. A new aluminum housing for the magnet structure minimizes overall resonance and improves the isolation parameters for the tweeter dome element. The long-throw voice coil enables lower distortion and optimal cutoff frequencies that enhance driver integration with the midrange driver.

Extraordinary midrange reproduction is attained from a proprietary 6-inch driver that is formulated using Multi-Wall carbon fibre and a layer of XG Nanographene, which when combined is 20% lighter and 300% stiffer than the previous S-series cone designs. The purpose-built sub-enclosure is made of a proprietary polymer material which provides an optimised environment for the midrange driver to operate within.

Deep, powerful, and accurate bass frequencies result from two newly designed 9-inch Magico bass drivers that are produced with advanced manufacturing techniques using a new Multi-Wall carbon, Nanographene cone. The powerful magnet structure controls a 5-inch pure Titanium voice coil that has a 1/2-inch of linear excursion and produces clean, undistorted sound pressure levels up to 112dB @ 50Hz/1-meter.

The monocoque enclosure of the S3 Mk II is formed from a single piece of extruded aluminum that is 3/8-inch thick and 12-inches in diameter. The new aluminum top plate is machined into an elegant 3D convex shape to minimize enclosure diffraction and break-up vertical standing waves. A massive 4-point outrigger base lowers the speaker’s center of gravity and increases stability and dynamic range.

All four drivers in the S3 Mk II are acoustically integrated using Magico’s exclusive Elliptical Symmetry Crossover topology that utilises state-of-the-art components from Mundorf of Germany. The dividing network maximises frequency bandwidth while preserving phase linearity and minimizing intermodulation distortion. Individual driver performance and the loudspeaker in its final form are tested and optimised for acoustical, mechanical, electromagnetic, and thermal behaviors using the latest state-of-the-art Finite Element Analysis simulation testing equipment.
