The monocoque enclosure of the S1 Mk II is formed from a single piece of extruded aluminium that is 3/8″ thick and 12″ in diameter. The slender enclosure is supported internally by a new innovative bracing technique along with advanced damping materials and glues that minimise resonance and maximize structural rigidity and stability. A massive new top plate is machined into an elegant 3D convex shape to minimize enclosure diffraction and break-up vertical standing waves.
Detailed and extended high frequencies are provided by the newly designed 1-inch Diamond coated Beryllium diaphragm tweeter – first introduced in the S7 – that offers matching sensitivity, wide dispersion and high power handling. A robust motor system and long throw voice coil enables lower distortion and cutoff frequencies never achieved before.
Captivating mid-bass performance is provided by a newly designed 7-inch mid bass driver that incorporates Mutli-Wall carbon nanotube and Nanographene which combined is 20% lighter and 300% stiffer than the previous cone material used in the original S1. A new underhung neodymium base motor system substantially increases the S1 Mk II power handling.
A massive new top plate is machined into an elegant 3D convex shape to minimize enclosure diffraction and break-up vertical standing waves. Newly designed 4-point outrigger assembly supports the S1 Mk II enclosure and optimises overall performance. The S1 Mk II is available a new M-Cast finish and the luxurious M-Coat painted finish.
