# [EX-DEMO] Wharfedale Diamond 12.1 Bookshelf Speakers - Light Oak

**Condition:** Speakers are in as-new condition with light use. Complete with box, grilles etc.

The Wharfedale DIAMOND 12.1 bookshelf speakers bring the history and performance values of the DIAMOND series to a compact, affordable standmount design, finished here in Light Oak.

They're a genuine all-rounder, equally at home driving a two-channel hi-fi system or anchoring a compact home theatre setup.

At the core of the DIAMOND 12.1 is a 130mm Klarity cone bass/mid driver, engineered for exceptional timing and refined bass.

It's paired with a 25mm woven polyester dome tweeter that delivers open, smoothly extended high frequencies.

Behind the drivers, an acoustic LKR crossover, Intelligent Spot Bracing and a precisely tuned rear-ported enclosure work together to keep colouration and resonance to a minimum.

-   **Klarity Cone Driver:** A blend of polypropylene and mica gives a lightweight, rigid 130mm cone for low colouration and lightning-fast response.
-   **Refined Treble:** A 25mm woven polyester dome tweeter delivers open, smoothly extended high frequencies.
-   **Precision Crossover:** An acoustic LKR 24dB topology uses air-core inductors for the lowest distortion of all inductor types.
-   **Intelligent Spot Bracing:** Computer-modelled bracing reduces cabinet resonance for a cleaner, more accurate sound.
-   **Rear-Ported Enclosure:** A precisely sized internal volume works in harmony with the drivers for a well-controlled low end.
