# Wharfedale Diamond 12 3Di Atmos Speakers (Pair)

The Wharfedale Diamond 12.3Di Atmos speakers are designed to add immersive height effects to a home cinema system, delivering overhead sound without the need for in-ceiling installation.

Ideal for Dolby Atmos setups, they sit neatly on top of compatible speakers or can be wall-mounted to create a more enveloping, three-dimensional soundstage.

Part of the Diamond 12i series from Wharfedale, the 12.3Di uses the same advanced driver technology and cabinet engineering found across the range.

This ensures seamless tonal matching with other Diamond speakers, making them a natural upgrade for existing Wharfedale-based surround systems.

**FEATURES**

-   **Dolby Atmos-Enabled Design**: Angled drivers project sound upwards, reflecting audio off the ceiling to create convincing height and overhead effects without visible ceiling speakers.
-   **Klarity™ Mid/Bass Driver**: A 100mm woven polypropylene cone delivers clean, controlled midrange performance, ensuring Atmos effects remain precise and well defined.
-   **Soft Dome Tweeter**: The 25mm textile dome tweeter provides smooth, detailed high frequencies for natural-sounding effects and ambience.
-   **Perfect Series Matching**: Voiced to integrate seamlessly with other Diamond 12 and 12i speakers for a cohesive surround sound experience.
-   **Flexible Placement Options**: Designed to sit on top of floorstanding or bookshelf speakers, or to be wall-mounted for added installation flexibility.
-   **Rigid, Low-Resonance Cabinet**: Internally braced construction reduces vibration, allowing Atmos effects to sound clear, accurate and immersive.
