Definitive Technology UIW RCS III
The RCS III features a D’Appolito driver array angled down and aimed at the listening area (two 4-1/2 inch cast-basket bass/midrange drivers and a 1" pure aluminum tweeter) as well as two 5-1/4 x 4-1/8 inch pressure-coupled planar low bass radiators. Proprietary Wave Launch (patent pending) baffle geometry and acoustic treatment materials serve to create the illusion that the speakers are directly in front of the listener rather than up in the ceiling.
The precisely configured dual angled baffles incorporate a uniquely effective acoustic treatment which combines a computer-optimized ribbed surface with special dampening panels in order to achieve a linear uncolored sound combined with boxless three-dimensional imaging in which acoustic events seem to effortlessly float in space.
In fact, the overall sonic performance of the RCS II is truly remarkable, combining breath-taking dynamics, engrossing musical subtlety and amazingly spacious imaging that totally belies its in-ceiling configuration.
Buying from an authorized dealer has many benefits such as valid warranty coverage on your purchase and peace of mind.

About Definitive Technology
Definitive Technology has been committed to building superior sounding home audio and home theater loudspeakers since 1990, when the company was founded by Sandy Gross, Don Givogue and Ed Blais—lifelong audiophiles and experts in speaker design, acoustics and marketing. Definitive Technology loudspeakers are among the most positively reviewed and most often honored high performance loudspeakers on the market as well as being the best-selling premium home loudspeakers in the US.
Since its inception, Definitive has won an astounding number of awards and over-the-top enthusiastic reviews from Consumer Electronics industry associations as well as leading audio/video print magazines and websites. Frankly there are too many to list them all here but the photo on this page gets the point across.
Most recently a speaker system consisting of Definitive Technology Mythos STS SuperTowers, Mythos Nine center and Mythos Gem surrounds was awarded Sound & Vision magazine’s “Audio Product of the Year;” not merely “Speaker of the Year” but “Audio Product of the Year.” The system also won SoundStage!.com’s 2008 Reviewer’s Choice Award for Aesthetics and Sound. Home Theater magazine called the STS system “Crisp, Lush, Focused” and tagged it with a coveted Top Pick award. The STS also took home two Innovations Design and Engineering awards at CES 2009, one for High Performance Audio and the other for Home Theater Speakers. One industry award is an honor, five is a sweep.
