Wharfedale DIAMOND12.4I 2.5 way Floorstanding speakers Pair in Walnut

Wharfedale Diamond 12.4i Floorstanding Speakers (Pair)

The Wharfedale Diamond 12.4i stands as the flagship floorstanding model of the refreshed Diamond 12i series, a range that elevates an already class-leading family of loudspeakers. While the original Diamond 12 lineup set the benchmark for affordable high-fidelity performance, the 12.4i introduces refined engineering, newly developed finishes, and subtle acoustic improvements—all without any increase in price. In today’s market, such value is almost unheard of.

A Natural Evolution of an Award-Winning Series

Since debuting in 2020, the Diamond 12 Series has earned consistent praise from critics, reviewers, and music lovers alike. Wharfedale leveraged five years of research, manufacturing enhancements, and aesthetic updates to create the Diamond 12i range—preserving everything listeners loved while improving performance in meaningful ways.

The 12.4i, as the larger floorstander, benefits from these upgrades in both sound and appearance, offering enhanced low-frequency control, cleaner bass articulation, and a more contemporary finish palette.

Premium New Finishes with a Modern Identity

Wharfedale has introduced luxurious, modern finishes that elevate the Diamond aesthetic:

• Deep Black – A smooth semi-matte finish ideal for minimalist interiors
• Stone Grey – A bold, modern tone that complements contemporary décor
• Classic Walnut – Warm and elegant, paired with a semi-matte black baffle

These finishes offer richness and consistency far above typical expectations at this price point, giving the speakers a premium presence in any room.

Refined Acoustic Performance Through Engineering Expertise

Behind the refreshed exterior lies a suite of carefully engineered upgrades focused on realism, control, and musicality. Minor adjustments to the bass reflex port geometry and internal damping deliver noticeably improved bass precision and midrange integration.

Wharfedale’s acoustic team—led by Director of Acoustic Design Peter Comeau—conducted months of testing using anechoic measurements, CFD airflow analysis, laser interferometry, and hundreds of hours of critical listening. The result is deeper, more articulate bass and smoother transitions between frequency ranges, preserving neutrality while enhancing engagement.

Klarity™ Cone Technology at the Core

The 12.4i continues to use Wharfedale’s advanced Klarity™ polypropylene/mica composite drivers:

• Lightweight, rigid construction for low distortion
• Well-damped behaviour for controlled and expressive dynamics
• Ribbed cone shaping for smooth, linear frequency response

Both 6.5-inch drivers—one for bass and one for midrange—deliver exceptional clarity with tight, well-controlled low-frequency impact.

Advanced Magnet System for Cleaner Output

Each mid/bass driver incorporates:

• A precision-engineered motor system
• An aluminium compensation ring to stabilise inductance
• A high-power epoxy/glass fibre bobbin for superior thermal stability

These features dramatically reduce intermodulation distortion and ensure accurate, articulate sound even at higher volumes.

25mm Textile Dome Tweeter for Smooth, Extended Highs

High frequencies are handled by a refined 25mm woven polyester dome with:

• High-loss damping coating for smooth treble response
• Minimal-waveguide front plate for enhanced dispersion
• Excellent off-axis performance for a wide listening sweet spot

The result is treble that is open, detailed, and natural.

Precision Crossover Design

Wharfedale employs a Linkwitz-Riley crossover using high-quality air-core inductors—components usually reserved for far more expensive speakers. Tuned for seamless phase alignment and tonal balance, the crossover ensures cohesive driver integration and accurate imaging.

Low-Resonance, High-Strength Cabinet Structure

The Diamond 12.4i cabinet uses a multi-layered wood fibre sandwich construction that significantly reduces panel resonance. Inside, Intelligent Spot Bracing connects opposing panels with modelled braces that suppress vibration without transferring energy across the enclosure.

This neutral, rigid structure allows the drivers to perform at their highest potential, offering a sound that is clean, dynamic, and beautifully controlled.

A Remarkable Upgrade That Keeps Its Heritage

The Diamond 12.4i looks, feels, and sounds like a thoroughly modern loudspeaker while retaining the qualities that made the original Diamond 12 series a best-seller. Its upgraded performance, refined finishes, and unchanged price make it one of the most compelling choices in its class—ideal for anyone seeking authoritative floorstanding sound with genuine high-fidelity character.
