Introducing Tranquility Base Carbon, the first all-new Tranquility Base in over a decade. SR started with a new chassis machined from a solid billet of aircraft aluminum for a 50% slimmer and 80% more rigid chassis. They then experimented with new laminates and arrived at carbon fiber for its superior response to mechanical and airborne vibrations. They then applied our most advanced EM Cell technology directly transferred from our Galileo SX PowerCell. Finally, its internal UEF Technology was transferred from our new state-of-the-art SRX cable loom. The net result is a thinner and more rigid Tranquility Base with a lower noise floor from which springs improved dynamics and soundstaging combined with smoother, more extended high frequencies.
