The Evolution of True Ribbon

The RAAL 1995 Magna EVO I is built around a newly developed dual-ribbon driver configuration designated as the R2e1 system. This architecture marks a significant evolutionary step in ribbon transducer design by introducing a segmented ribbon array that treats different zones of the human ear independently.

The specialized mechanics of this technology operate on several key fronts:

Segmented Ear-Zone Interaction

Instead of projecting a uniform acoustic wavefront across the entire outer ear, the R2e1 motor splits the transduction work between physically distinct front and rear ribbon segments:

• The Rear Ribbon Segment (Acoustic Damping): Positioned directly over the concha (the ear shell) and antihelix, this ribbon is covered with a specialized open-cell hard foam progressive damping layer. This acoustic foam absorbs and moderates upper-midrange and lower-treble energy, actively suppressing bouncing wave reflections in the concha to eliminate sibilance, harshness, and listening fatigue.

• The Front Ribbon Segment (Direct High-Frequency Delivery): Placed directly above the ear canal, this ribbon segment remains completely open and unobstructed. Because the corresponding zone of the ear does not naturally over-amplify high frequencies, treble energy projects straight into the canal to deliver linear, effortless high-frequency extension, pristine air, and the highly resolved micro-detail often described as "diamond dust".

Excursion Control and Low-End Power

Under the hood, the R2e1 motor implements enhanced ribbon excursion control and power handling. This mechanical refinement allows the pure aluminum ribbons to vibrate safely and precisely over larger physical distances. This structural control allows the Magna EVO I to extend its low-frequency response much deeper into the sub-bass octaves compared to the original Magna, delivering a warmer, thicker, and highly authoritative bass response that carries realistic physical weight and punch.
