Sonus Faber Amati Futura

This listing is for a pair of Amati Futura speakers. They are the red finish and are in mint condition. I’m the original owner and they have been gently used in my home theater. They are carefully packed in the original packing and boxes. Shipping cost is the responsibility of the buyer and will be arranged after the sale with the buyer. 

Amati Futura
The Amati Futura is a Lute-shaped 3.5 way floor standing speaker. Through the use of "Stealth" reflex construction featuring a fully optimized decoupling system between speaker and floor and by using the Sonus Faber's "LVT" system (low vibration transmission) a "TMD" (Tuned Mass Damper) mechanical and sound vibration virtually eliminated. Also borrowed from the "The Sonus Faber," is the para-aperiodic "Stealth Reflex" technology employed internally as a resonator providing additional reduction of stray residual resonance in the lower frequency ranges by converting the kinetic energy into heat. 

Acoustic Enclosure
The enclosure is a fundamental component of Sonus faber's patented sound design. The progressively rounded, multi-layered sidewalls are constructed in a self-damped ("constrained layer damping") construction. This "acoustic environment" has been optimized for each driver through strategically located reinforcement ribs in each of the drive unit's individual acoustic chamber. The adaptation of these methodologies allows each driver used to come as close a possible to the theoretical performance ideal.

Innovative Features
A massive clamp consisting of two CNC machined nickel-Avional cones (Avional is a high strength aluminum alloy of 4.75% copper, 0.5% magnesium and 1.4% silicon) is used to halt cabinet vibration and resonance. The top and the bottom plates of the device act like an "exo-skeleton ensuring that any resonances within the enclosures walls are controlled and eradicated. The opposing end pieces are held together by a double wing-like metal brace at the rear of the enclosure. Together they function as a high-speed conductor for the rapid dissipation of resonance into the cone-shaped base casing.

A "Tuned Mass Damper", which is essentially a shock absorber for moving mass, absorbs specifically tuned frequencies converting any residual resonances into a thermo-kinetic state. Similar construction techniques to reduce resonance have been used in skyscrapers and Formula 1 cars. The speaker's exceptional performance is also somewhat due to the patented "LVT" system (low vibration transmission) that mechanically decouples the speaker from the floor. It uses an advanced elastomer-based suspension system reducing unwanted resonances transmitted into the listening room, whereby any acoustic feedback effects are effectively thwarted.

The "Stealth Reflex Port" is Sonus Faber's patented solution for the realization of a para-aperiodic enclosure ventilation system. The properties of this system allows for deep, extended bass with the same or less cabinet volume. In addition, it has all the advantages of conventional ports but eliminates the inherent "chuffing" sound completely.
