Wharfedale Diamond 11.0 Speakers . As Wharfedale celebrates its 85th birthday, the company’s classic Diamond lineage of high-performance, high-value speakers reaches new heights with the Diamond 11 Series.
Sporting extensive improvements both inside and out, the Wharfedale Diamond 11.0 Speakers represents the most significantly enhanced Diamond series in years.
The mist immediately obvious change is a return to the elegantly curved cabinet sides made famous by Diamond 9 and Diamond 10 ranges which yielded What Hi-Fi? Product of the year awards in 2005 and 2009 for the Diamond 9.1 and 10.1 respectively.
Wharfedale Diamond 11.0 Speakers
The crossover integration in the Wharfedale Diamond 11.0s uses a highly evolved virtual crossover software system which works to help create a series of circuit options that will combine the bass/midrange and treble units seamlessly.
Said circuit options are then evaluated using stringent listening tests over a period of months, involving a wide variety of different music.
After the final circuit strategy has been chosen, the design team fine-tunes the crossover component values, the component types and the circuit board layout in order to yield an accurate, detailed and enjoyable performance with only listening test as an arbiter of quality.
Special attention has been paid to the Wharfedale Diamond 11.0’s lifelike qualities in vocals and natural instruments.
This attention to fine-tuning is what gives these speakers their enduring appeal in the affordable sector of the Hi-Fi market.
The cabinets of the Wharfedale Diamond 11.0 Speakers have been made using a refined multi-layer sandwich of woods of differing density in order to subdue the identifiable characteristics of the cabinet ‘sound’, thus letting the drive units speak for themselves.
The cabinet’s critical bracing, together with the curving of the cabinet walls – designed as such to provide a shape that is not boxy – have reduced resonances more than 25dB below the driver outputs.
These cabinet walls are also lined with a specially developed internal fibre, chosen due to its outstanding absorbent qualities across a wide bandwidth.
The result lets the listener hear the drive unit output unsullied by any unwanted colourations caused by panel vibration or internal resonances, allowing for a more revealing performance when it comes to the detail of the music.
The slot-loaded distributed port is a recent Diamond innovation that was first introduced in 2012 in the Diamond 100 series.
The internal port tube opens into a slot formed between the cabinet and the plinth, reducing turbulence and audible ‘chuffing’ that more conventionally ported systems would suffer from when a sudden outrush of high pressure air makes its way into the low pressure in the room.
A further benefit is to increase the efficiency of energy transfer from the bass reflex tuning to the room.
Both ends of the port have been have been profiled with a semi-parabolic entry and exit curve, linearising airflow through the port tube.
This has allowed Wharfedale to increase the volume of air in the slot-loaded system, improving the performance of the low frequency output even further and resulting in an entirely natural and low-distortion recreation of the fundamental notes of bass instruments.
This will match the realistic sound in the midrange and treble characteristics. The low ‘Q’ nature of the ported system will allow the listener to position these speakers close to a rear wall, allowing the speaker to become less obtrusive in a room setting.
While drawing on the ground-breaking research undertaken for the award winning Diamond 200 and Reva series of speakers, Diamond 11 has I fact been completely redesigned both inside and out from the cabinets to the whole new drive units, offering state-of-the-art tonal accuracy and musical detail.
