# Wharfedale Diamond 12.3i Floorstanding Speakers (Pair)

The Wharfedale Diamond 12.3i floorstanding speakers are designed to deliver powerful, room-filling sound while maintaining the refined balance the Diamond series is known for.

Ideal for medium to larger living rooms, they offer deeper bass, greater scale and improved dynamics compared to bookshelf models, making them perfect for both music and home cinema systems.

As part of the Diamond 12i range from Wharfedale, the 12.3i combines advanced driver technology with a rigid, low-resonance cabinet.

The result is a confident, engaging sound that brings music, films and TV to life without overwhelming the room.

**FEATURES**

-   **Dual Klarity™ Mid/Bass Drivers**: Two 130mm woven polypropylene drivers deliver controlled, punchy bass with clear, expressive midrange detail.
-   **Refined Dome Tweeter**: A 25mm textile dome tweeter produces smooth, natural high frequencies with excellent detail and minimal listening fatigue.
-   **True Floorstanding Performance**: Taller cabinet design provides greater low-frequency extension and a wider, more immersive soundstage.
-   **Rear Bass Reflex Port**: Improves bass depth and efficiency, helping the speakers sound full and balanced even at lower volumes.
-   **Easy Amplifier Compatibility**: A friendly impedance and sensitivity make the Diamond 12.3i easy to pair with a wide range of hi-fi and AV amplifiers.
-   **Low-Resonance Cabinet Construction**: Internally braced cabinet minimises vibration, allowing the drivers to perform cleanly and accurately.
