Amphion BaseTWO25 Stereo Bass Extension System The Amphion BaseTWO25 Stereo Bass Extension System is a high-end stereo bass extension system designed to transform passive 2-way studio monitors into a fully integrated 3-way full-range monitoring system. Developed by Amphion Loudspeakers, it follows a unique concept: stereo imaging is preserved all the way down to the lowest frequencies. The system consists of two bass extender towers featuring dual-sided 10″ aluminum woofers and passive radiators in a force-cancelling configuration. It is powered by an external amplifier with an integrated discrete filtering module and selectable crossover settings. By handling low-frequency reproduction, the system reduces the load on the main monitors, improving midrange clarity, dynamic headroom and overall accuracy. Sound Character The BaseTWO25 delivers extremely deep, powerful and highly controlled low-end performance. Unlike conventional subwoofer systems, it maintains stereo imaging in the bass range, resulting in a more realistic and better translating sound. The low end is tight, detailed and balanced, while mids and highs benefit from increased clarity due to reduced workload on the main monitors. The result is a cohesive, three-dimensional full-range monitoring system with exceptional precision.

Amphion FLEXBASE25 Bass Extension System The Amphion FLEXBASE25 Bass Extension System is a professional stereo bass extension system designed to transform 2-way studio monitors into a full-range 3-way monitoring system. Developed by Amphion Loudspeakers, it follows a unique concept: instead of a traditional mono subwoofer, it preserves stereo information all the way down to the lowest frequencies. The system consists of a central bass unit with dual 10″ aluminum drivers and the external FlexAmp1200 amplifier. With up to 2 × 700 watts of power, it delivers outstanding headroom and low-frequency control. By handling low frequencies, the system reduces the workload on the main monitors, significantly improving midrange clarity and overall precision. Sound Character The FLEXBASE25 adds deep, controlled and highly accurate low-end extension without coloring the sound. Unlike conventional subwoofers, it maintains stereo imaging in the bass range, resulting in a more realistic and better translating listening experience. Low frequencies are powerful and detailed, while mids and highs benefit from improved clarity due to reduced load on the main monitors. The result is a balanced, full-range monitoring system with exceptional accuracy.
