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.

Rear-firing twin reflex ports:  The speaker’s twin reflex ports have been moved to the rear of the cabinet, to reduce the effects of audible distortion. These ports extend the bass to below 45Hz, contributing to an impressive sense of sonic scale.

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.

Offset Bi-Wire Terminals:  Utilizing the same familiar offset terminal block as with its predecessors, the gold-plated contact areas and bridging strips allow firm connections with the best possible connectivity, whilst the offset pattern provides allowance for heavy duty cables and a wider range of cable connection options.
