New plinth with tuned-mass damping All floor-standing models in the new D5 range include a substantially revised aluminium plinth that has been carefully re-profiled to match the form of each corresponding loudspeaker cabinet. In a further nod to improved aesthetics, the supporting legs underneath the loudspeaker gain a new high quality metal trim while the lower edge of the plinth has been extended downwards to help conceal the wheels and spikes below the loudspeaker.
To improve performance, each plinth is designed to resist unwanted vibration using a combination of constrained-layer and tuned-mass damping. The new tuned masses are individually specified to suit the unique properties of each plinth and further help minimise unwanted output of the loudspeaker. All four plinths have been further refined with the addition of stabilising outriggers engineered to sit inside the plinth itself, further enhancing the design detailing.
All-new aluminium top plate Greatly benefitting from the modelling and simulation work that was carried out on the 801 D4 Signature, the new D5 design introduces a substantially revised aluminium plate that braces the top section of each cabinet. With thicker aluminium ribbing sections for greater stiffness, more mechanical location points to optimise coupling to the top of the enclosure and revised decoupling mounts to support the Turbine Head or Solid-Body-Tweeter assembly, the outcome is improved mechanical behaviour at the top of each cabinet.
Each aluminium top plate is further refined with an upgraded collar trimmed in Leather by Connolly and critically damped with material derived from the 800 Series D4 Signature loudspeakers, further reducing unwanted output from the aluminium plate it physically connects to.
Enhanced Matrix Building on the already phenomenally stiff Matrix™ Bracing system found in the 800
Series Diamond range, the new Enhanced Matrix™ adds greatly increased stiffness to the critical area at the front of the cabinet around each individual drive unit. Using thick sections of aluminium that have been carefully profiled to brace around each drive unit aperture and further stiffened with ribbed sections to the rear, the Enhanced Matrix joins the newly introduced Space Frame Bracing and all-new aluminium top plate in providing massive increases in cabinet stiffness and commensurate reductions in unwanted noise.
Aluminium mid-range enclosure( 804 D5) Marking one of the most significant new technology introductions in the range, the new 804 D5 has been substantially revised to include an internal aluminium enclosure for its Continuum Cone FST™ assembly. Derived from the hugely stiff Turbine Head structure used on all larger floorstanding models in the 800 Series Diamond range, the aluminium enclosure both isolates the midrange assembly and provides a incredibly consistent mechanical decoupling point for the drive unit itself. The result is a more free and open sound from the Continuum Cone midrange that more effectively emulates the spatial presentation of a true headed model, such as the 803 D5. At the same time, the 804 D5 retains the more conventional aesthetic that marks it out as the most discreet choice of floorstanding model in the range.
