Wharfedale Diamond 11.2 Bookshelf Speakers (PAIR)
The Wharfedale Diamond 11.2 Bookshelf Speaker is a classic entry point to true high-fidelity sound, their exceptional value for money earning numerous ‘product of the year’ awards in the UK and around the world. Now, with the introduction of the all-new Diamond 11 Series, Wharfedale has once again raised the bar for affordable, high-performance loudspeakers.
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 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 many music lovers, not just the wealthy few.
Advanced driver systems of the Wharfedale Diamond 11.2 Bookshelf Speakers (PAIR)
Diamond 11 features 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 top plate with copper cap controls the magnetic flux and ensures low distortion through the critical midrange area.
Then there is the suspension which features a lightweight progressive rubber surround, in conjunction with a super-long-throw voice coil motor system, to achieve unparalleled linearity and accuracy in this sector of the market.
Cabinet construction of the Wharfedale Diamond 11.2 Bookshelf Speakers (PAIR)
While the cabinet, to the owner, is often just a piece of furniture, at Wharfedale we have long realised that it is the final piece of the design process that marks a loudspeaker out of the ordinary.
For Diamond 11 our engineers have refined the multi-layer sandwich of differing woods to subdue the identifiable characteristics of the cabinet ‘sound’ and so let the drive units speak for themselves.
Critical bracing of the cabinet panels and, of course, the curving of the cabinet walls to provide a non-boxy shape, have reduced resonances more than 25dB below the driver outputs. In addition we use a specially developed internal fibre to line the cabinet walls which has been chosen because of its outstanding absorbent qualities across a wide bandwidth.
Slot-loaded distributed port available on the Wharfedale Diamond 11.2 Bookshelf Speakers (PAIR)
The slot-loaded distributed port is a recent Diamond innovation where the internal port tube opens into a slot formed between the cabinet and the plinth. This not only reduces the turbulence caused by the sudden outrush of high pressure air into the low pressure in the room, suffered by conventional ported systems, but also increases the efficiency of transfer of energy from the bass reflex tuning to the room.
For Diamond 11 we have taken this one stage further, profiling both ends of the port with a semi-parabolic exit curve that linearises airflow through the port tube. This has allowed us to increase the volume of air in the slot loaded system and further improve the performance of the low frequency output.
The result is an entirely natural and low distortion recreation of the fundamental notes of bass instruments, matching the realistic sound of the midrange and treble characteristics. The low Q nature of this ported system also allows the listener to position Diamond 11 speakers close to a rear wall, helping to make the speakers less obtrusive in a room setting.
