The coherence of the midrange and treble balance provides a highly musical and natural delivery of all types of music that positively encourage exploration of any CD, LP and MP3 collection. The overall result of the engineering changes is to deliver a tightly focused and spacious stereo image allied to a clean and clear performance throughout the audioble bandwidth. Other Diamond series attributes remain, like the sturdy bi-wire terminal block, high quality silicon iron and air cored inductors in the crossover, high purity copper internal wiring and an interference free front grille, now affixed without unsightly pegs in the piano-black finish front baffle. Over the treble unit is a metal diffusion grid which, as well as protecting the dome when the speaker is being used without its grille, also irons out high frequency perturbations right up to 30kHz giving a super-smooth response and crystal clear treble detailing.Įqually for low frequency analysis twin reflec ports extend bass to below 45 Hz and have been re-positioned on the rear of the cabinet to reduce the effects of audible distortion. This enable the relatively simple crossover to yield a phase perfect integration to the treble unit throughout the whle crossover region, creating a soundstage which is free from the speakers and allowing the drive units to work as a cohesive whole. This is more than just cosmetic as the pattern reduces and damps standing waves in the surround yeilding a cleaner high frequency acoustic roll-off.
The discerning audiophile will also note the diamond pattern moulded into the surround of the woven Kevlar cone. The front baffle also has a composite panel structure to reduce vibration. To make the most of the stonger cabinet the bass unit, with a chassis formed from strong, nylon filled, homopolymer, has been given a massive flange secured to the cabinet with six screws to improve its stability. This both increases the rigigity of the cabinet structure and, aided by internal bracing, reduces the audible effects of panel resonance. The concept of a curved wall cabinet for strength and reduction of internal standing waves has been maintained and, in the Diamond 10 series, the cabinet walls have been made stronger through a superior method of bonding and curving the panels. But Wharfedale engineers were determined to bring the latest Diamind right into line with the standard of performance expected from a stand mount/bookshelf speaker in 2009.
Following the highly successful and award winning Diamond 9 series was always going to be a difficult task.
