Description:Definitive Technology® Reference In-Ceiling Loudspeakers with patented Wave Launch technology creates the illusion that the speakers are in front of you, not above you
Features:<p> The RCS III features a D&#39;Appolito driver array angled down and aimed at the listening area (two 4-1/2 inch cast-basket bass/midrange drivers and a 1&quot; 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.&nbsp;In addition, the RCS III with its active driver/bass radiator combination achieves an extended low-frequency response, which is deep and dynamic with a smooth and controlled roll-off that allows it to seamlessly blend with a subwoofer with a quality that has never been previously achieved in an in-ceiling system. Of course, the in-wall IWSub 10/10 or the UIW Sub Reference is the perfect complement to the RCS II for unmatched performance in a stealth home theater.</p> <ul> <li> Patented Wave Launch technology creates the illusion that the speakers are in front of you, not above you</li> <li> Two 4-1/2 inch cast basket drivers and 5-1/4 x 4-1/8 inch pressure-coupled Low Bass radiators for impressive deep bass with high impact punch</li> <li> Integrated wood enclosure ensures consistent high performance every time</li> <li> One 1 inch Pure aluminum dome tweeter</li> <li> Installs in either new or existing construction applications</li> </ul> <p> <strong>Warranty Information</strong></p> <ul> <li> Electronic components- 3 Years Parts and Labor</li> <li> Drivers and Cabinet- 5 Years Parts and Labor</li> </ul>
