OSD Black R63 6.5" Reference Carbon Trimless In-Ceiling Speakers (Pair)
The OSD Black R63 6.5-Inch Reference Carbon Trimless In-Ceiling Speakers (Pair) represent the gold standard of architectural home audio, combining aerospace-grade woven carbon fiber with a 1-inch ceramic-coated aluminum dome tweeter. Handling 150 watts of peak power (75W RMS) at 8 ohms across 40Hz to 20kHz, the R63 features front-baffle bass and treble contour switches, a precision crossover network with audiophile capacitors, and an edge-to-edge magnetic trimless grille that blends seamlessly into high-end residential interiors.
If you want to know what 6.5-inch in-ceiling speaker pair delivers audiophile resolution with deep 40Hz bass and zero cone distortion, how woven carbon fiber cones maintain pistonic accuracy during intense musical passages, or how a ceramic-coated aluminum tweeter eliminates high-frequency harshness, the OSD Black R63 is the premier choice. Homeowners and custom integrators choose the R63 for high-end whole-home music systems and immersive Dolby Atmos home theaters.

Aerospace-Grade Woven Carbon Fiber Woofer
Constructed with lightweight, ultra-stiff woven carbon fiber and a durable TPR rubber surround, the 6.5-inch woofer delivers lightning-fast transient response, tight bass, and uncolored vocal midrange.
Ceramic-Coated Aluminum Pivoting Tweeter
The 1-inch ceramic-coated aluminum dome tweeter combines the stiffness of aluminum with the dampening properties of ceramic, eliminating high-frequency resonances while pivoting up to 15 degrees to direct highs toward your listening position.
Dual Acoustic Contour Switches (+/-3dB)
Features independent front-panel toggle switches for both bass and treble (+/-3dB), allowing installers to calibrate acoustic balance for acoustically lively hardwood rooms or heavily carpeted environments.
Zero-Bezel Magnetic Trimless Architecture
An ultra-thin magnetic grille covers the mounting frame completely, delivering an elegant flush profile that can be painted to match any ceiling color.
