Introduction

Invisible Speakers are the pinnacle of the Sonance “Designed to Disappear” strategy. High frequencies are achieved with Sonance’s “Motion Flex Technology”, which consists of a “Wave Flex Drive Unit” with a bending wave diaphragm, utilizing a 1.75” (44mm) voice coil, while the low frequencies are generated by an “Air Flex” Woofer with an air pulse diaphragm driven by an 6.5” (165mm) carbon fiber woofer.
