Diaframma a matrice in fibre di aramide e materiale cellulare rigido leggero.I diaframmi per il woofer e il driver delle medie frequenze sono realizzati in esclusivo materiale cellulare rigido leggero di Sony, precedentementee noto come materiale cellulare rinforzato in mica. The latest generation compound has been further optimised with improved mechanical drivers for even greater frequency response and more fluid and natural audio characteristics.Integrazione in una matrix esclusiva con fibre in aramide elimina la risonanza del diaframma e riduce al minimo la distorsione, non solo nei bassi, ma anche nelle frequenze medie e alte. The surround woofer is equipped with a different proprietary technology, with exclusive tacche curves that increase the simmetria of the vertical amplitude to drastically reduce distortion and improve loudness.Cinque cornici structure and dinamico diffuser: the cinque cornici design disperses the resonance while the integrated diffuser ensures optimum air circulation for the operation of the hose cone and the refinement of the coil.The spider is optimised from an acoustic point of view and provides greater power and improved air flow, with a profile designed for faster and more precise cone adjustment.Spine di fase .Le spine di fase per lo smorzamento della risonanza sul woofer XS-163ES e il mid-range driver permettono di raggiungere una risposta in frequenza ideale, fino ai punti di crossover. The rigid aluminium voice coil in the woofer and the dinamic air diffuser further support the speaker's wide frequency response, for controlled, dynamic audio.
