Descripción
A reference monitor remaining true to the Finnish innovator’s core strengths with the benefits of an active design.
Amphion One25A is a 3-way studio monitor that is true to Amphion core strengths of advanced
acoustic design, simple signal path, naturalness and high level resolution enhanced with the
benefits of active design, without any of the downsides.
Know-how from the highest level of instrument building was applied for resonance control
and energy transfer to ensure that not only the technical, but also goals regarding emotionality
and musicality, were met. An innovative sealed dual cabinet improves clarity of all frequencies
by separating the midrange from the hexagon shaped bass enclosure, which eliminates
standing waves. Plenty of amplifier headroom, elegant simple active crossover, and protection
limiter, which is only in the signal path when needed all contribute to highest level of
resolution.
