Rosso Fiorentino Siena 2

The Siena stands as one of Rosso Fiorentino’s flagship models, meticulously designed to serve as the ultimate reference loudspeaker for medium-sized rooms—nothing less. The adoption of a sealed enclosure system was a deliberate decision aimed at achieving an ultra-wide frequency response and a commanding yet impeccably balanced acoustic presence that feels natural and effortlessly integrated.

The Siena speaker system features a precisely engineered modular closed-box structure, developed for exceptional acoustic performance. Aluminum cone woofers and paper cone midranges are mounted using an advanced vibration-damping system, significantly reducing energy transfer to the baffle. The top unit is decoupled from the woofer section with viscoelastic discs, enhancing clarity in the mid and high frequencies.

The cabinet’s trapezoidal shape minimizes internal standing waves, while its construction—combining high-density fiberboard (HDF), aluminum paneling, and internal viscoelastic lining—effectively suppresses vibrations and dissipates resonant energy, thereby reducing structure-borne interference. This carefully engineered design is further enhanced by a precise combination of fibrous damping materials and strategically placed air-cushion resonators, optimizing internal damping for outstanding clarity, articulation, and natural tonal balance.

The high-frequency section features an Italian-made silk dome tweeter with specialized damping treatment, ensuring smooth, fatigue-free treble with remarkable dynamic linearity. Complementing it is a Rosso Fiorentino-designed ribbon ultrasonic generator, extending frequency response up to 100kHz to enhance spatial depth. A custom 18 cm Scan-Speak midrange driver, engineered specifically for this model, delivers outstanding linearity, controlled dispersion, and natural tonality. Two aluminum-diaphragm woofers provide precise, distortion-free bass, optimized for the sealed cabinet to deliver deep, articulate low-frequency reproduction with excellent transient response and control.

Siena’s sophisticated three-way crossover network combines premium components from leading manufacturers with Rosso Fiorentino’s own custom coils and uniquely selected elements to ensure absolute sonic purity. Advanced filtering techniques integrate all five drivers into a seamless point-source configuration. A dedicated impedance optimization circuit stabilizes the amplifier load, enhancing both efficiency and musicality. To further preserve signal integrity, the crossover network is divided across three separate supports, reducing electromagnetic interference. This meticulous engineering guarantees precise driver alignment and coordination, revealing every musical detail with exceptional transparency and resolution.

Every facet of Siena’s electroacoustic design is purpose-built for optimal performance. The strategic arrangement of the drivers maintains phase coherence and enhances off-axis response, creating a balanced sound signature across different listening environments. The enclosure’s damping system eliminates structure-borne vibrations, contributing to improved clarity in low-frequency reproduction. Designed as a reference loudspeaker for medium-sized spaces, Siena achieves an ultra-wide frequency response, a richly layered soundstage, and a naturally balanced tonal character. This holistic design approach ensures a refined, immersive listening experience that faithfully captures the full emotional depth of the original recording.
