With the Diamond Series, Wharfedale laid the bar several times in the field of affordable and high-quality speakers. With the Wharfedale Diamond 11 series they have shifted this bar once again.
The Diamond 11 Series Speakers are equipped with solid magnetic designs to increase both sensitivity and to ensure absolute control over the cone movement on the lower bass frequencies. In addition, the use of a specially formed single forged pole piece with copper cap controls the magnetic flux and ensures low distortion in the critical midrange area.
The Diamond 11 series has design components that have never been seen against such an affordable price. At the start of the design process, the engineers of Wharfedale returned to the base to create a speaker system that would bring many music lovers.
