Fibonacci Technologies Phoenix Ribbon Monitor

Front_Gray_Poster_2A complete re-thinking of the capabilities and limitations of the unique Fibonacci 1.1 Gen 3.3 Ribbon Transducer led us to the Phoenix, a whole new twist on the fundamental nature of ribbon loudspeakers. 

Phoenix is build with a unique, diffraction-optimized cabinet that is a very comfortable 66 inches tall.

One would think that a transducer originally designed to reproduce human voice more accurately than any other loudspeaker in history may not make the ultimate two channel loudspeaker, but in fact the Fibonacci 1.1 Gen 3.1 transducer’s  astounding vocal accuracy lends itself to every other instrument as well.  Phoenix reproduces music with natural timing and liquidity and communicates a fluid sense of harmonic continuity that even the best conventional loudspeakers can not match.

Unlike every other ribbon loudspeaker in history, the Phoenix ribbon is housed in a optimized Aperiodically Damped Acoustic Suspension cabinet. 

Phoenix can be configured for Near Wall Specific placement, where the back, bottom of the cabinet is within one foot of the wall and the bottom spikes adjusted for optimum rake angle.  Near wall specific placement reduces the power requirement by a factor of four, as this placement takes maximum advantage of both upper bass boost and the Allision Boundary Effect and offers the smoothest coupling to the room.

By flicking a switch on the rear of the speaker, it is reconfigured for free-field placement, optimally four feet out from the back wall and any other boundary, the classic two-channel configuration preferred by most audiophiles. 

Phoenix can accomplish these things equally well placed closely to wall or in free field. 

Phoenix requires a subwoofer, with the low pass crossover frequency set between 130Hz and 160Hz (depending on placement), and sounds best with a dedicated electronic crossover with a high pass matched 160Hz as well.
