Modern home audio demands a balance between high-quality sound and seamless design integration. With the rise of recessed LED ceiling lights, homeowners and designers alike seek audio solutions that blend effortlessly into existing aesthetics. The OSD Black R43 and R43SQ in-ceiling speakers provide an ideal solution, offering high-fidelity sound in a small-aperture format that matches the most popular 6-inch ceiling light fixtures.

Small Aperture, Big Performance

Despite their compact size, the OSD Black R43 and R43SQ deliver an impressive sound experience. Many small in-ceiling speakers compromise on audio quality, but these models stand out with a separate 4-inch polypropylene woofer and 0.5-inch PEI dome tweeter. This combination ensures crisp highs, clear vocals, and a balanced low-end response. With a frequency response extending down to 70Hz (-10dB), these speakers offer a rich and immersive soundstage.

Seamless Integration with Home Design

Trimless Magnetic Grille: The R43 features a round, micro-perforated white grille, while the R43SQ includes a square grille for those who prefer a different aesthetic. Both options are paintable, allowing them to blend perfectly with your ceiling.
Dolby Atmos Ready: These speakers can serve as height-channel speakers in Dolby Atmos setups, offering precise placement for overhead audio effects in home theater applications.
Rear Dust Cover: A built-in dust cover prevents debris from affecting performance, ensuring long-term reliability.

High-Output, Low Distortion

Capable of handling 50W RMS and 100W max power, these speakers can achieve volumes over 100dB without noticeable distortion. This makes them suitable for background music, immersive home theater setups, or even high-energy entertainment spaces.
