The WHARFEDALE DIAMOND 11.2 SPEAKERS need little introduction. With nearly three decades of supremacy within the sector, numerous international awards and over 1 million pairs sold worldwide they are arguably ‘THE’ most recognisable name in the world of audio.
The Diamond 11 series builds on the innovative acoustic technology and superb aesthetics which made the previous series fresh and visually exciting. With the introduction of the all-new Diamond 11 Series, Wharfedale has once again raised the bar for affordable, high-performance loudspeakers.
Now you’ve heard the hyperboles: A certain product is touted better than those costing three times as much and possesses technological details nobody but the designers understand. All this from manufacturers that have been in business just a few years. We sympathise with your skepticism. So does Wharfedale.
Don’t judge this 2-way speaker by its relatively modest size. Whether playing classic-rock favourites or mellow jazz, the WHARFEDALE DIAMOND 11.2 SPEAKERS exhibit spacious dynamics and astute control no matter the program material. It begs to be placed in an office, den, bedroom, porch, lounge, or modest-sized listening room – anywhere you want to hear rich, involving sound.
Enhancements Focus on Delivering Best-Possible Sound Quality: How does Wharfedale do it? Improving on past award-winning designs, the 11.2 features a soft-dome tweeter custom-made to present clear, high frequency ranges up to 20kHz. A 150mm (6″) Kevlar bass driver and a bottom firing port to bring up the bottom end and yield tremendous punch. Lets look at these enhancements more closely.
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 11 series drivers should be aimed at performance and that is why they sport advanced driver systems incorporating elements that normally only find their way into high-end loudspeakers. For example, the bass and mid-range drivers use a basket with a network of ribs that maintain the rigidity of the basket while leaving a large open area behind the cone. The rigidity improves transient impact while the big open area reduces early reflections to cone and allows the generous, specially chosen internal cabinet absorbent to do its work.
The Diamond 11 Series speakers also feature massive magnet designs to both raise sensitivity and ensure absolute control of cone movement over lower bass frequencies. In addition, the use of a specially shaped single-forged pole piece with copper cap controls the magnetic flux and ensures low distortion through the critical mid-range area.
Then there is the progressive suspension which features a lightweight foamed surround for an extended mid-range response, in conjunction with a super-long-throw voice coil motor system, to achieve unparalleled linearity and accuracy in this sector of the market. Naturally the woven Kevlar cone, a long-time favourite for Diamond designs, has been treated to provide a precise match to the new suspension elements.
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 mid-range performance in addition to precise high-frequency detailing.
