Hard-wired crossovers are used throughout the Turnberry SE and the routing of each cable has been painstakingly considered to ensure there is no degradation in sound quality. Similarly, the components have been carefully arranged to avoid any coupling effects. In particular, incredible transparency in the mid band has been achieved providing an enhanced true-to-life vocal clarity. Completely redesigned crossovers, incorporating the most up-to-date high quality components, have taken these models to a new level of acoustic excellence. ICW Clarity Caps have been included for high frequency (HF) section of the crossovers, while high quality metalised film capacitors are used in LF sections. The LF crossover also makes use of very low loss laminated iron core inductors. Internal connections from input terminals to crossover, internal crossover wiring and crossover to Dual Concentricâ„¢ drive unit are made with the exceptional VDH MC CS18 halogen free silver-plated cable.
A 5-point terminal panel (bi-wire and ground point) gold plated terminals has been incorporated on the Turnberry SE. With the driver chassis grounded via the 5th terminal, and 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.
