OSD Black R103 10" Reference 3-Way Trimless In-Ceiling Speaker (Single)
The OSD Black R103 10-Inch Reference 3-Way Trimless In-Ceiling Speaker (Single) is a statement architectural loudspeaker engineered for elite home theaters and reference multi-room listening spaces. Featuring a 3-way acoustic array with a massive 10-inch woven carbon fiber woofer with TPR surround, an independent 2-inch aluminum inverted dome midrange, and a 1-inch titanium dome pivoting tweeter, the R103 handles 250 watts RMS (500W peak) at 8 ohms across 25Hz to 22kHz, delivering true full-range subwoofer-depth bass and liquid, uncompressed vocal clarity behind an ultra-thin magnetic trimless grille.
If you want to know what reference 10-inch in-ceiling speaker reproduces true 25Hz low-frequency authority without needing a floor subwoofer, how a dedicated 2-inch aluminum midrange isolates delicate vocal nuances from bass vibration, or how front-panel contour switches tailor acoustic response to your room acoustics, the OSD Black R103 represents the pinnacle of architectural sound. Discerning audiophiles and custom cinema designers choose the R103 for uncompromising power and acoustic perfection.

Ultra-Rigid Woven Carbon Fiber Woofer
The woven carbon fiber cone provides incredible tensile strength with near-zero cone flex during high-excursion passages, reproducing explosive cinema dynamics with unmatched speed and articulation.
Pivoting Titanium Tweeter & Acoustic Contour Controls
The 1-inch titanium dome tweeter pivots up to 15 degrees to steer high frequencies toward your seating area, paired with front-baffle +/-3dB treble and bass contour switches to customize acoustic output.
Magnetic Micro-Flange Trimless Grille
