Definitive UIW RCS III in-ceiling speaker

Excellent overhead sound from Def Tech Designing a custom-installed home theater? Definitive Technology's UIW RCS (Reference Line Source) III in-ceiling speaker uses an angled-baffle design to bring sound down and toward you, making it a great choice for the front left, center, or right channel in your surround system. Pair the UIW RCS III with Reference Line Source in-wall speakers for seamless, voice-matched sound throughout your room. The integrated sealed enclosure helps deliver excellent sound while keeping dust and dirt away. Dual passive radiators help deliver extra punch The UIW RCS III pairs two 4-1/2" polypropylene midrange/bass drivers with a 1" aluminum dome tweeter to produce the natural, revealing sound Def Tech is known for. Dual 5-1/4" x 4-1/8" pressure-coupled passive radiators help reinforce this in-ceiling speaker's impressive bass output. A built-in enclosure elevates performance One of my favorite features of the UIW RCS III is the back-box that's built onto the speaker. This carefully designed enclosure helps the speaker deliver consistently focused, well-balanced sound no matter what kind of space is behind it in your ceiling. It also keeps dust and dirt out. DIY installation You can paint the included grille to have your speaker blend in with your room's decor.
