&#8220;Quad-brid&#8221; design, based on an advanced array of drivers and a low-noise crossover network, tuned to perfection.\u00a0Four varieties of drivers, including special armature radiators, a planar driver, a 10mm dynamic driver and a piezoelectric transducer, create a perfect synergy, coming together to form the Quad-brid AK ZERO2, capable of reproducing the pure sounds that Astell&Kern strives to deliver.<\/p>\n<p>The flat isodynamic driver with micro-rectangular diaphragm is a driver designed specifically for high frequencies, which uses advanced technology that allows the use of a planar driver in headphones, despite the great complexity of its manufacture in such a small housing.\u00a0A light but strong planar membrane provides a clear and dynamic response at high frequencies.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2023\/04\/159_techweek.jpg\" alt=\"\" width=\"825\" height=\"438\" \/><\/p>\n<p>Two balanced armature radiators deliver a perfectly balanced rich sound, specially tuned for each frequency range, which reproduces great sounds.<\/p>\n<p>The 10mm speaker used in the AK ZERO2 is manufactured with the utmost care using a fully automated process.\u00a0This allows the speaker to reproduce rich and deep low frequencies.<\/p>\n<p>An additional piezoelectric transducer works with the speaker to act as a super tweeter that reproduces the extremely high frequencies that many IEMs struggle with.<\/p>\n<p>The ultra-finish crossover network provides the perfect balance between six drivers with different sonic characteristics, maximizing each of their acoustic properties and creating a balanced, cohesive sound.<\/p>\n<!-- FeedbackWP Plugin --><div
