Definitive Technology UIW RLS II In-wall multi-purpose speaker with built-in back-box

The Definitive Technology UIW RLS II is a premium in-wall speaker designed to deliver exceptional sound without occupying any floor space. Part of the Reference Line Source (RLS) series, this speaker provides spacious, high-fidelity audio, making it perfect for home theater setups or custom-installed stereo systems. It can function as a left-, right-, or center-channel speaker, adapting seamlessly to various configurations.

One of its standout features is the built-in sealed wooden back-box, which ensures consistent, high-quality sound regardless of the wall cavity size. This design helps prevent sound distortion, enhances clarity, and minimizes audio leakage into adjacent rooms. The airtight enclosure also protects internal components from dust and dirt, ensuring long-term durability.

The UIW RLS II features a 1-inch aluminum dome tweeter for crisp, detailed highs and dual 6.5-inch polypropylene cone midrange/bass drivers that deliver powerful, balanced audio. Additionally, two 6.5-inch pressure-coupled passive radiators extend the bass response, enhancing low-frequency performance without requiring an external subwoofer.

With a slim, paintable magnetic grille, this speaker blends effortlessly into any décor, maintaining a clean and unobtrusive appearance. It is also compatible with the RLS II rough-in kit for easier installation. Whether used in a dedicated home theater or as part of a high-end music system, the UIW RLS II provides a rich, immersive audio experience.
