“When Wharfedale launched the very first Diamond in 1981, the company defined a new class of speaker that delivered genuine hi-fi accuracy and musical brio at a remarkably affordable price. Since then, every iteration of the famous Diamond line has adhered to that tradition but improved upon it. With the Diamond 11 Series we started afresh, taking established Diamond design features like Kevlar bass/mid cones and the slot-loaded distributed port system and incorporating them into entirely redesigned speakers, superior in every way from the cabinets, to the drive units, to the crossover.
The result of our technical endeavours is unquestionably the best Diamond range yet, delivering a natural sense of space and musical communication that is both instantly engaging and consistently appealing in the long term. These speakers draw the listener into the musical performance in a way normally expected only from models at considerably higher price levels, embodying the traditional Wharfedale attribute of being great all-rounders across various music types. Add the elegantly curved and immaculately finished cabinets and we are proud to have created a range of speakers that delivers premium quality at remarkably affordable prices – entirely fitting with Wharfedale’s 85-year legacy.” Quote from Peter Comeau – Wharfedale’s Director of Acoustic Design
The latest generation of Diamond speakers includes design elements never previously seen at such affordable price points. At the start of the design process, Wharfedale’s engineers went back to basics in order to create a loudspeaker system that would once again revolutionise this sector of the hi-fi market and bring high-end performance – and style – within reach of most music lovers, not just the wealthy few.
Advanced driver systems
Whereas most affordable speaker systems are based on drive units that are built down to a price, Wharfedale started with the premise that Diamond drivers should be aimed at performance. That is why the Diamond 11 Series sports advanced driver systems incorporating elements normally only found in high-end loudspeakers, such as:
- Bass and midrange driver baskets with a network of ribs for added strength, improving among other things transient impact
- Massive magnet designs improving sensitivity and control of cone movement
- Specially shaped single-forged pole piece with copper cap controls the magnetic flux and reducing low distortion through the critical midrange area
- Progressive suspension featuring lightweight foamed surround for an extended midrange response
- super-long-throw voice coil motor system to achieve unparalleled linearity and accuracy
- Woven Kevlar cones
High-frequency performance has been similarly enhanced with a newly evolved tweeter design. Again, an over-sized ceramic magnet system is used, with a copper cap for flux control. And, here, the pole piece is vented through to a specially shaped rear chamber. This provides a low resonant frequency, ensuring excellent linearity throughout the operating system and allowing the textile dome to contribute to a lucid midrange performance in addition to precise high-frequency detailing.
