Responsible for this challenging job are two 7 inch subwoofers mounted inside a horn loaded bass reflex cabinet, powered by Ncore amplifiers. An active electronic system for analogue room size and placement correction is used to tune the speaker to roll off as a closed box speaker, so it does not suffer from problems normally associated with ported speakers. Many other technologies and materials of the Stilla are more directly derived from the closed-box Ensis speaker and the Stilla is equipped with the same formidable midrange driver. The result is a comparable character with rich audiophile musicality as well as transparent uncoloured precision and an amazing holographic soundstage.
The middle and high frequency section of this hybrid speaker remains passive. Specified as 8 ohms nominal and highly sensitive, it is made to work well with a wide range of amplifiers. The five inch driver is responsible for very open, or pleasantly detailed, midrange frequencies without coloration. It is accompanied by a tweeter system with a concentric dome and ring moving-surface, as well as some new dispersion-improvement technologies. The two transducers are time-aligned by the carefully sloped cabinet, and wideband phase-aligned by the low-order crossover, to deliver a spectacular, holographic soundstage.
A fully active version of the Stilla is also available.
