Place The Speaker in A Corner RCS III loudspeaker

The RCS III loudspeaker is also available as a floor-standing model. It is the same height as a standard floor-standing loudspeaker but has a much larger driver area. It contains the equivalent of two three-way speakers, but they are mounted in a sealed enclosure that provides nearly identical performance regardless of available air space. The D'Appolito driver array includes 5.25" (13.34 cm) and 4.5" (11.43 cm) bass/midrange drivers and a one-inch pure aluminum tweeter. These drivers are enclosed in a dense wood cabinet that prevents vibrational interference and delivers uncolored midrange and tight bass.

Features and Proprietary

The RCS III loudspeaker features a proprietary baffle geometry that improves dispersion into the room. The RCS III loudspeaker also features a patent-pending Wave Launch system that reshapes sound waves. The UIW RCS III is a great option for those who want a high-quality home theatre speaker without the cost of a full-blown home theater system.

The RCS III loudspeaker also features an active driver/bass radiator combination, which provides smooth roll-off and surrounds sound. The aluminum dome tweeter is also ultralight and delivers superior midrange and bass performance. The RCS III loudspeaker also features two 5-1/4" x 4-1/4" pressure-coupled planar low bass radiators. The RCS III is the most advanced in-wall loudspeaker available today. It features a non-resonant sealed Mediate enclosure that produces a smooth roll-off and provides uncolored midrange and tight bass.

UIW RCS III loudspeaker is a type of in-ceiling speaker that was developed after six years of rigorous research and development. It is designed to be mounted flush in the ceiling and offers the best level of construction quality and sonic performance. The aluminum dome tweeter delivers a high-frequency response, while the active driver/bass radiator combination provides smooth roll-off and surround sound. It can also play significantly higher frequencies than most of us can hear. The RCS III loudspeaker is ideal for invisible home theatre systems.

The RCS III uses an aluminum dome tweeter that can play significantly higher frequencies than most of us can notice.

The RCS III also has a patent pending Wave Launch system that uses dual-angled baffles. The RCS III is also designed to blend seamlessly with the Sub Reference. It has a small footprint and takes up little floor space. They are expected to ship this fall that is easy to use and easy to carry any place.
