The Siena stands as one of our flagship models, meticulously designed to be our ultimate reference for medium-sized rooms—nothing less. The decision to adopt a sealed enclosure system was driven by this very objective: delivering an ultra-wide frequency response, a commanding yet impeccably balanced acoustic presence that always feels natural and effortlessly integrated.
The Siena speaker system features a meticulously engineered modular closed-box structure, designed for exceptional acoustic performance. The aluminum cone woofers and paper cone midranges are mounted with an advanced vibration-damping system, significantly reducing energy transfer to the baffle. The top unit is decoupled from the woofer section using viscoelastic discs, enhancing clarity in the mid and high frequencies.
The cabinet’s trapezoidal design minimizes internal standing waves, while its construction—combining high-density fiberboard (HDF), aluminum paneling, and an internal viscoelastic lining—effectively suppresses vibrations and dissipates resonant energy, reducing structure-borne interference. This carefully engineered design, complemented by a precise blend of fibrous materials and strategically placed air-cushion resonators, optimizes internal damping, ensuring outstanding clarity, articulation, and a natural tonal balance.
The Siena’s high-frequency section features an Italian-made silk dome tweeter with a specialized damping treatment, ensuring smooth, fatigue-free treble with remarkable dynamic linearity. Complementing this is a Rosso-designed ribbon ultrasonic generator, extending up to 100kHz for enhanced spatial depth. The 18 cm Scan Speak midrange driver, specially engineered for this system, delivers exceptional linearity, controlled dispersion, and natural tonality. Two woofers with aluminum diaphragms provide precise, distortion-free bass. Optimized for a sealed enclosure, they maintain outstanding linear excursion and motion control, ensuring deep, articulate low-frequency reproduction with excellent transient response.
Siena’s sophisticated three-way crossover network combines premium components from renowned manufacturers with Rosso’s custom coils and a carefully curated selection of unique elements, ensuring absolute sonic purity. Advanced filtering seamlessly integrates all five drivers into a coherent point-source. A dedicated impedance optimization circuit stabilizes the amplifier load, enhancing efficiency and musicality. To preserve signal integrity, the crossover is distributed across three separate supports, minimizing electromagnetic interference. This meticulous engineering guarantees precise driver coordination, unveiling every musical nuance with exceptional transparency and resolution.
Every aspect of Siena’s electroacoustic design is meticulously crafted for optimal performance. The strategic arrangement of drivers maintains phase coherence and enhances off-axis response, ensuring a balanced sound signature across various listening environments. The enclosure’s damping system prevents structure-borne vibrations, improving low-frequency clarity. Designed as a reference for medium-sized rooms, Siena achieves an ultra-wide frequency response, a three-dimensional soundstage, and a natural tonal balance. This holistic approach guarantees a refined, immersive listening experience, faithfully reproducing every nuance of the original recording.
