From Amphion Loudspeakers

FlexBase25 is a single box, stereo bass system, which transforms a two-way studio monitor into a fullrange, three-way system. The system comes with FlexAmp1200 with wide adjustment possibilities allowing to address the needs of a rapidly changing landscape of modern sound-making.

 

Unique highlights 

Stereo to the lowest octave

Amphion’s introduced their first Base Extension system in 2015. The concept of keeping stereo information all the way down has become widely adopted since.

 

Seamless integration

Designed to work seamlessly with all monitor sizes. System can even be paired with a smaller model for an ultra-fast, easy to adjust small room full-range system.

 

Elevate your monitors

As the bass frequencies are transferred to the Base system, the midrange clarity and power-handling of the paired monitors are greatly enhanced.

 

Industry-defining clarity

Force-cancelling driver configuration and highest quality components lead into industry-defining clarity, control, and low frequency detail.

 

Simple setup

Always placed under the monitors. Fixed placement and physical proximity between the monitor and bass extender ensure perfect integration.

 

2-way, 3-way or Amphion way?

Simplicity of a 2-way monitor or the power handling of a 3-way design? The system can easily switch between both with a push of a button or foot switch.
