Monoprice 2-Way In-Ceiling Speakers - 6.5 Inch, Dual Input Stereo, Glass Composite Woofer (Pair) - Aria Series

These in-ceiling speakers feature a triple driver design with two pivoting titanium silk membrane dome tweeters for superior sonic performance. The woofer is constructed of an advanced glass composite to deliver high fidelity, distortion-free audio. Each speaker features two sets of speaker wire terminals, allowing you to wire each speaker for single-speaker stereo. When using single speaker stereo, you can achieve good stereo separation by pointing the tweeters in different directions to allow the sound to reflect around and fill the room.
Features: Exotic glass composite woofer for distortion free reproduction. Oversized magnets for more impactful bass. Dual precision titanium silk membrane dome tweeters for broad frequency spectrum, sweeter highs and pure sonic clarity. Pivoting tweeters allow you to point the acoustics to the prime listening position for a more accurate and immersive sonic experience. 40W nominal and 100W maximum power handling capacity provides ample headroom so these drivers won't be easily overdriven or blown out. 8ohms standard impedance ensure they can be safely driven by even the most modest home theater receivers.
