Composite front baffle panel: The front baffle features a composite panel structure with a piano-black finish. This contributes to the speaker’s smart new look and, more importantly, to its improved sound quality, as it reduces the effects of vibration and provides a stable platform for the drive units.
Tweeter diffuser: Over the soft-dome tweeter 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, delivering a smoother response and crystal-clear treble detailing.
Enhanced front grille with ‘invisible’ fixing: The front grille has been improved to ensure it has no adverse effect on the speaker’s performance. In addition, it is now affixed without pegs, therefore eschewing the need for unsightly holes in the piano-black finish front baffle.
Low Profile Chassis: The open nature of the chassis reduces reflection from rear cone movements, allowing air to move freely through the driver, which in turn results to an overall even response with a much lower distortion. Formed from a high density, injection-moulded polymer pioneered by Wharfedale, the chassis itself provides substantial damping of ring waves.
