Wharfedale Diamond 12.4i Floor-Standing Speakers (Pair)

Shine on with the Wharfedale Diamond 12.4i Floor-Standing Speakers: Range Flagship Features a Pair of 6.5-Inch Klarity Drivers and Offers Spectacular Control, Focus, Depth, and Immediacy 

Anchored by a 6.5-inch woofer and 6.5-inch bass/midrange driver, the Wharfedale Diamond 12.4i floor-standing loudspeakers play with a focus, liveliness, immediacy, transparency, and openness mostly off-limits to other models anywhere near their price class. Proudly expanding on the Diamond Series heritage originally established more than three decades ago, Wharfedale considered every aspect of Diamond 12i Series so that each speaker in the line performs with optimal results. A sophisticated voice coil, precision-based parts, and computer-modeled bracing are just a few of the audiophile-minded advantages that yield natural, richly expressive sound. 

Ditto a redesigned port crafted using laser interferometry, anechoic measurements, and computational fluid dynamics to access airflow and pressure in its structure. This helps the 45.27 x 7.87 x 14.88-inch (HWD) Diamond 12.4i offer articulate and controlled bass responsiveness as well as consistent spatial performance.

With fantastic low-end capabilities, Diamond 12.4i features advanced drivers comprised of trademarked Klarity cone material – formulated from a blend of polypropylene and mica to add stiffness while remaining lightweight for low coloration and fast responsiveness. Fitted with a low-damping surround and shaped to achieve a flat response curve, it produces expressive dynamics even on complex material.

Each driver also possesses a precision-crafted magnet system with an aluminum compensation ring to minimize the effect of variations in inductance as the voice coil travels, ultimately leading to an absence of distortion and intermodulation generated by the motor system. As for the aforementioned voice coil, it comes wound on an epoxy/glass-fiber bobbin produces higher power handling than those assembled on aluminum machines.

When it comes to highs, Diamond 12.4i will take you there. Comprised of woven polyester film with a high-loss coating for open, smoothly extended high frequencies, its one-inch textile-dome tweeter boasts an optimized magnet system and flat front plate to attain wide dispersion and uncompressed playback. Architecturally, a very short duct on the front plate balances the acoustic load and serves to improve SPL measurement. Diamond 12.4i also utilizes a Linkwitz-Riley crossover with air-core inductors – the latter commonly found in much more expensive high-end designs due to their low-distortion properties.

Sporting a fit and finish intended to instill pride of ownership, Diamond 12.4i takes the elegance of its namesake stone with utmost seriousness. It also benefits form-follows-function architecture in which Intelligent Spot Bracing connects opposite walls with a custom, computer-modeled wood brace to reduce resonance – and not transfer it from side to another. In addition, the rear-ported enclosure works in harmony with the drive unit to produce the sound you deserve to hear.

As the flagship in a series that has literally redefined what's possible from budget-friendly speakers for more than 30 years, Diamond 12.4i will make you a believer in high-end audio and the differences it makes on how – and what – you hear. 

Driver Magnet Systems
Each mid/bass driver features a precise magnet system with an aluminum compensation ring to reduce the effects of inductance changes as the voice coil moves. This advanced motor system minimizes intermodulation and distortion, producing cleaner, more accurate sound. The voice coil is wrapped around a high-power epoxy/glass-fiber bobbin, which performs significantly better than standard materials at this price point, offering greater power handling, thermal stability, and structural strength.

High-End Crossovers
Wharfedale engineers use a sophisticated Linkwitz-Riley crossover design complete with air-core inductors — components typically found in high-end speakers. The crossover network is finely adjusted for minimal phase shift and smooth integration between drivers. The magnet structure for the mid/bass driver is modified to address the resistance of the high-quality inductors, ensuring
fast, clean bass without compromise.

Low-Resonance Cabinets
Each enclosure features a multi-layered sandwich construction that reduces panel resonance and distortion. Even the adhesive properties between the layers have been acoustically tested to optimize damping. Inside, intelligent spot bracing connects opposite cabinet walls using computer-modeled braces that reduce vibration without passing it from one surface to another. This contributes to the solid and authoritative sound signature of the Diamond 12i series.
