Wharfedale - Diamond 10.4

Stronger cabinet walls: The concept of curved cabinet walls, for strength and the reduction of internal standing waves, has been retained from the Diamond 9 Series. However, these walls have been made stronger through a superior method of bonding and curving the panels, increasing rigidity and, aided by internal bracing, reducing the audible effects of panel resonance.

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.

Improvements to the mid/bass drive unit: To make the most of the stronger cabinet, the main drive unit chassis has been enhanced with a massive flange that is secured using six screws, thus improving its stability. A diamond pattern has also been moulded into the surround of the Kevlar cone; this is more than just cosmetic as the pattern reduces and damps standing waves in the surround, yielding a cleaner high-frequency acoustic roll-off and enhancing the ability of the mid/bass unit and tweeter to work as a cohesive whole.
