Wharfedale Diamond 12.2 Speaker Review

Wharfedale Diamond 12.2 speaker test

Wharfedale is a renowned British audio brand, best known for its high-quality loudspeakers. Headquartered in the United Kingdom, the brand is currently part of the International Audio Group (IAG).

While Wharfedale has previously manufactured televisions, DVD players, set-top boxes, and Hi-Fi systems, the company has focused exclusively on audio equipment since 2008. Its legacy traces back to 1932, when Gilbert Briggs founded Wharfedale Wireless Works. Over the decades, the company has established itself as one of Britain’s leading manufacturers of audiophile-grade speakers and audio components.

Features

While the speakers remain compact in size, the cabinet volume and driver dimensions have been increased to enhance overall efficiency—making them ideal for larger rooms and more powerful 2-channel hi-fi setups.

The Diamond series is equipped with twelve high-performance 150mm Klarity™ drivers, engineered for tight, extended bass, along with a 25mm woven polyester dome tweeter designed to deliver clean and extended high frequencies. The Klarity™ cone—crafted from a blend of polypropylene and mica—is both lightweight and rigid, ensuring sonic accuracy and durability. Its surface features reinforcing ribs that enhance stiffness, contributing to controlled bass and reducing unwanted resonances and response delays.

The magnetic assembly includes an aluminum compensation ring, which helps minimize distortion as the voice coil moves, preserving audio clarity at all volumes.

Unusually for this price range, the voice coil is wound on a high-performance epoxy/fiberglass former, ensuring superior thermal and mechanical stability.

The speaker’s crossover network features an acoustic LKR 24dB topology, known for delivering minimal distortion. To compensate for the higher resistance of its air-core inductors—compared to standard laminated steel or ferrite versions—the magnetic structure of the mid/bass driver has been modified. This results in fast, clean bass response with no inductor-induced distortion.

Inside the cabinet, Intelligent Spot Bracing optimally reduces cabinet resonance. The stiffeners were accurately modelled by computer simulation for this purpose. Speaker sensitivity is 88 dB, recommended amplifier power 20-120W, maximum sound pressure (SPL) 96dB, frequency response (+/- 3dB) 50Hz ~ 20kHz, dimensions (L x W x D) 335 x 200 x (285 + 28) mm, the weight is 8.2 kg / pc.

Wharfedale Diamond 12.2 bass reflex speaker testing

This is another stunning Diamond bookshelf speaker that is basically one of the cheaper two-way bookshelf speakers.

This Diamond model looks completely different from its predecessor and also differs in sound. While the Diamond 11 has a curved look, the Diamond 12 with its angular appearance suggests greater precision and enhanced dynamics. It has a more dynamic sound compared to the previous model. The Diamond 12.2’s fast, tight bass, focused stage image and detailed treble result in excellent sound. As for the exterior design, this time a more traditional back (bass reflex) box is used.

The housing of the Diamond 12.2 has a multi-layer sandwich design to reduce resonance. In terms of size, it is a compact yet not lightweight speaker that can be felt when lifted. There are connectors on the back of the speaker that allow for dual cabling and amplification.

Sound

For testing purposes, we paired the Diamond speakers with the Denon AVR-X540BT receiver, also available at an affordable price. We tested the speakers in a medium-sized room. The room, which used to be a garage, has been transformed into a home cinema and hi-fi room. Double wood membrane wall sound-absorbing panels as well as diffuser front acoustic panels were used to treat the walls of the room, a thick, dense acoustic carpet was placed on the hard-surfaced floor, thus optimising the acoustics of the room.

Based on the 88 nominal sensitivities, I found that the Diamond 12.2 speaker is a relatively easy-to-use speaker, but we would still recommend a higher power amplifier to deal with impedance drops (which can reach up to 4 ohms). Beware of cheap AVRs and stereo receivers.

We placed the Diamond speakers on metal stands, about two and a half meters from the wall behind them, and about three meters from the side walls. They were about 6 feet from the listening position. When placing the speakers, it is very important not to place them directly against the wall if possible to achieve the ideal sound.

Listening Experience

From the very first listen, the Wharfedale Diamond 12.2 impresses with its balanced and refined sound, especially considering its price point. These speakers deliver excellent dynamics, with crisp high-end detail, a precise midrange, and tight, impactful bass that truly stands out.

While the soundstage isn’t the widest in its class, it is deep and tall enough to create a convincing 3D effect—comparable to speakers that cost twice as much. In side-by-side comparisons, the Diamond 12.2 truly shines like an uncut gem, holding its own against more expensive competitors.

Instrumental tracks are rendered with such clarity that each instrument is distinct and well-defined. However, the sound can occasionally feel a bit too directional, and some listeners may perceive a slight lack of warmth in certain recordings. These characteristics were also noted during movie playback, though the overall soundstage and imaging remained top-tier, and the bass performance was consistently dynamic, deep, and accurate.

Conclusion

The Wharfedale Diamond 12.2 offers exceptional value for discerning listeners who want high-fidelity sound without breaking the bank. With its dynamic range, clarity, and refined craftsmanship, it stands as a strong contender in the bookshelf speaker category.

Whether you’re enjoying music or watching movies, the Diamond 12.2 delivers a rich, engaging listening experience that defies its affordable price tag.

Design & Value

The Wharfedale Diamond 12.2 is offered at a truly affordable price, and impressively, this budget-friendly cost does not come at the expense of design or sound quality. The speaker sports a clean, minimalist, boxy design that blends well into most interiors. Thanks to advanced engineering, the cabinet’s resonance is kept to a minimum, ensuring sound remains tight and uncolored.

Within its price category, the Diamond 12.2 has few real rivals when it comes to dynamic, clear, and accurate audio performance. While some may prefer a slightly warmer tone, this is more a matter of personal taste than a flaw. Despite its compact size, the sound easily fills larger rooms, and for optimal performance, pairing it with a higher-powered amplifier is recommended.

Final Recommendation

For those seeking a high-quality, budget-conscious speaker that doesn’t compromise on sound, the Wharfedale Diamond 12.2 is a standout choice. Whether you’re listening to your favorite albums or enjoying a home theater experience, these speakers deliver clarity, depth, and power far beyond what their price suggests.
