Definitive Technology Reference Three-Way White In-Ceiling Speaker， Model UIWRCSIII

The RCS III are in-ceiling front main， center， or surround speakers for built-in home theater installations. They feature two 4-1/2" cast basket active drivers and a Pure Aluminum tweeter on an angled baffle aimed at the listening area. Proprietary Wave Length (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 active drivers are pressure-coupled to two 5-1/4" race-track Low-Bass Radiators for exceptional bass and perfect blending with free-standing or built-in subwoofers.
