Having re-evaluated the performance of models throughout the Prestige range, Tannoy engineers selected the latest cutting edge components and materials at their disposal to introduce several performance enhancing amendments to the crossover topologies within the 'SE' models. To optimise acoustic performance only components of the highest possible standard have been used.
Westminster Royal SE benefits from Acrolink® cable right through from terminal panel to crossover, crossover to drivers and the LF board wiring itself; not forgetting the bi-wire links. Cables produced by Acrolink® use self-stipulated 6N copper, constructed using the same process as is used with wires for semiconductor devices, which require a guarantee of high quality. More precisely, the purity of the copper needs to be over 99.9999% and the total of any impurity metals must be less than 1 part per million. The quality of this cable ensures that a powerful yet delicate and natural, fast response is accomplished throughout the signal path.
Very low loss laminated iron core inductors on the LF ensure that there is less resistance between the amplifier and driver, resulting in superior bass control. High purity silver (99.99%) link wires maintain signal path integrity on the separate HF crossover board and for the HF feed capacitor Hovland Musicaps® are used with a special Tannoy DMT™ (Differential Material Technology) isolation sleeve. Hovland Musicaps® are renowned for their exceptional dynamics, speed, focus, correct timbre and depth of field, and true inter-transient silence. Separate layers of polypropylene film and conductive foil deliver superior clarity of reproduction that metalised capacitors cannot match.
High quality ICW Musicaps are used in other areas. Vishay thick film non-inductive resistors are used in critical areas, with extensive heat sinking where necessary. The stable component temperature provided by the heat-sinking feature ensures maximum reliability and an even and consistent sound quality.
The 5-point (bi-wire and ground point) terminal panel uses gold plated terminals, with the driver chassis grounded via the 5th terminal. By using appropriate speaker cable, this proven technology, developed on earlier Prestige models, minimises the effects of RF interference resulting in a more transparent midrange. Additionally the Westminster Royal SE uses high quality WBT™ connectors to ensure easier connection of substantial loudspeaker cable whilst maintaining complete signal path integrity.
