OSD Audio Black R43 4-Inch In-Ceiling Speaker (Pair)
Description
The OSD Audio Black R43 is a premium small-aperture in-ceiling speaker designed to deliver exceptional full-range sound while blending seamlessly with modern architectural lighting. Part of OSD Audio's flagship Black Series, the R43 is specifically engineered to match the size of standard recessed LED ceiling lights, making it an ideal choice for luxury homes, media rooms, whole-home audio systems, and Dolby Atmos® overhead speaker installations.
Despite its compact 4-inch design, the R43 features a dedicated polypropylene woofer and a separate 0.5-inch PEI dome tweeter that produce impressive clarity, balanced vocals, and dynamic performance. Capable of delivering sound pressure levels exceeding 100dB with minimal distortion, the speaker offers a rich listening experience that far exceeds expectations for its size. The extended bass response also allows it to be used independently or paired with a subwoofer for a more immersive audio experience.
The trimless magnetic micro-perforated grille can be painted to match any ceiling, while the integrated rear dust cover protects the drivers from debris and enhances long-term reliability. Compatible with most amplifiers and AV receivers, the R43 is equally suited for background music, multi-room audio, and immersive Dolby Atmos® home theatre systems.
