Monoprice 2-Way In-Ceiling Speakers (Pair) — 5-1/4-Inch, 50W Nominal / 100W Max, Aramid Fiber Fiber Cone Driver

Aramid fiber cone: extremely light, very rigid and highly durable, the aramid fiber driver delivers clean, punchy bass while keeping weight and distortion to a minimum. As a lightweight transducer it produces a natural sound with far less distortion than conventional drivers. Pivoting titanium silk dome tweeters provide adjustable high-frequency reproduction, offering airy, detailed clarity and well-defined vocals and dialog when the speakers are installed.
