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 Mk2 power handling.
