Wharfedale Diamond 250 Floorstanding Speakers

Flagship Model Delivers Perpetual Enjoyment and Phenomenal Price-to-Performance Ratio: Wharfedale Diamond 250 Tower Loudspeaker Will Change the Way You Experience Music

Diamonds are forever. Particularly when the diamond at issue is the Wharfedale Diamond 250 tower loudspeaker. Clear, balanced, immediate, and dynamically involving, the three-way floorstander provides perpetual music enjoyment. Diamond 250 provides exquisite audiophile sound marked by tremendous energy, gorgeous tonality, deep bass, smooth mids, and extended highs. Built to play with nonfatiguing ease, two 7.9-inch bass drivers and a 5.1-inch midrange driver complement a soft-dome tweeter equipped with an advanced ferrite magnet system. This elegant speaker draws listeners into their music in emotionally compelling ways traditionally only associated from much costlier models.

The Diamond 200 Series flagship, Diamond 250 touts significant enhancements that impact its design, construction, performance, and looks. Upgraded speaker materials, woven Kevlar woofers, fine-tuned crossovers, updated bass and treble units, and a slot-loaded port are just a few of the internal features that account for the speaker’s stellar capability. Yet you’ll likely be too busy preoccupied with what you experience outside to worry about particulars. That’s the sign of a great speaker – and one that is 100% Music Direct Guaranteed to forever change the way you experience music.

New Speaker Materials Reduce Coloration, Block Internal Cabinet Noise
Ongoing research into new cabinet materials and loudspeaker drivers yields the foundation for Diamond 250, which improves upon its predecessors in terms of design, construction, execution, and aesthetics. Diamond 250 boasts the latest acoustic technology to produce an involving listening experience that cannot be beat at this price point. Fieldwork and testing that resulted in the implementation of Crystalam (a substance that reduces the audibility of panel resonance and the ‘cabinet hear-through’ that causes distinct coloration) in Wharfedale’s flagship Jade Series has now been applied to the far less-expensive Diamond 250. In Diamond 250, a simpler combination of particleboard and MDF supplies similar reductions in coloration, damps annoying high-frequency resonances, and blocks internal sound leakage.

Slot-Loaded Port Improves Efficiency, Fine-Tuned Crossovers Enhance Integration
Derived from the Jade Series’ Aperiodic bass-loading system, a slot-loaded distributed port created by the plinth exits the base of the speaker cabinet. It allows for greater freedom of speaker positioning, meaning Diamond 250 can be placed as close as two feet from a wall and still operate at peak potential. Most speakers cannot achieve this feat. The port also equalizes the air pressure to mimic the pressure inside the cabinet, permitting a smooth transition between the pressure variation in the cabinet and low-frequency sound developed in the room. Consequently, the energy transfer is increased, and overall system efficiency strengthened. Computer-assisted modeling and hundreds of hours of tests ensure each speaker is fine-tuned. The same process is employed to fine-tune the crossover, which betters the integration between the drive units and intensifies the musical realism. Music lovers will relish audiophile sound whether listening either on and off-axis.

Updates to Bass Motors and Treble Unit Yield More Power, Better Midrange 
Bass unit motor systems are also significantly refined. Increases in magnet sizes, where applicable, beget higher-sensitivity systems that both make the speakers easier to drive and boost transient acoustic power. Semi-elliptical break-up areas on the speakers’ signature woven-Kevlar woofer smooth the response, while the cone edges are treated with a unique diamond-pattern molding. To further facilitate outstanding midrange response, Diamond 250’s tweeter uses a sheer fabric dome and advanced ferrite magnet system surrounded by a carefully crafted waveguide. The latter smooths the transition between the midrange and tweeter in the crossover region, producing extremely coherent sound between the drivers.

Lacquered Front Baffle and Superb Veneer Finishes Boost Aesthetic Appeal 
Destined to elegantly blend into any room, Diamond 250 stylistically benefits from a new lacquered front baffle and cosmetically enhanced veneers. The simple, one-piece baffle that tops the hybrid cabinet material is lacquered to a highly polished finish that cosmetically matches the diamond-cut drive unit surrounds. In addition, the inner and outer layers of MDF allow for a superior finish to the cabinet veneers, enhancing the prior look available on Diamond 100 Series.

Extending a Proud Heritage
Wharfedale Diamond Series reigns as one of the most successful hi-fi loudspeaker lines in history, earning worldwide accommodates for delivering award-winning sound at prices everyone can afford. Since its debut in 1982, Diamond models have subscribed to the principle that stellar performance could – and should – be available at a cost that brings more listeners closer to the music they love. Adhering to that brilliant heritage, Diamond 200 Series reveals entirely new levels of musical detail and transient attack, drawing listeners into musical performances in emotionally compelling ways traditionally only expected from speakers that command much higher prices.

Diamond 200 Series

Quite simply put, the Wharfedale Diamond is one of our most successful speaker series, if not one of the most successful hi-fi speaker series ever. We can justify this as year on year, the Diamond Series has broke the mould for combining award winning sound quality unforeseen at this price.

From 1982 Wharfedale Diamond has meant one thing – impeccable performance at an affordable price. Today we are pleased to bring you the latest series of loudspeakers from Wharfedale that aspires to this tradition – Diamond 200 Series.

Foremost in the design criteria for Diamond 200 is the ongoing research into loudspeaker driver sound quality. The speaker series uses our famous woven Kevlar cone form, drawing influence from the flagship Jade Series.

While honing the internal crossover and using stronger magnets on the rear of the Diamond 220 for example, aesthetics and construction have been improved too. The Diamond 200 Series benefits from an all new lacquered front baffle and cosmetically enhanced veneers.

Only when the acousting tests are deemed truly satisfying are the loudspeakers designs signed-off for production, ensuring that each speaker model fulfils its eventual owner’s dreams of musically enjoyable reproduction from Britain’s Most Famous Loudspeakers.
