The UIW RCS II in-ceiling speaker produces phenomenally rich and immersive sound while it disappears above, virtually hidden in your ceiling. It’s technology that took decades to perfect, but will only take you milliseconds to appreciate. UIW RCS II speakers feature precisely-aimed drivers in our patented Wave Launch configuration – including two cast-basket midrange/woofers and a pure aluminum tweeter – angled downward toward the listening area for a full audio experience.
