Stereo bass-extension and management system with a separate LFE-channel input and 600W amplifier
Nailing the lowest octave-settings and translating it precisely from a studio to any listening situation is the foremost challenge for any contemporary music production. The fragmented playback environment demands extreme precision in the process of music creation and sound editing, especially when it comes to modern, bass-heavy production.
A single mono subwoofer is part of a movie format, but Amphion does not believe it is good enough to be used in music production. In music, it is necessary to keep the stereo information throughout the whole frequency band. Amphion's FlexBase25 presents you with an unconventional approach to subwoofer design that will satisfy even the most demanding producers or sound engineers.
The FlexBase is a stereo bass extension and management system with a separate LFE-channel input. The crossover frequency is variable between 35-260 Hz, which allows changing the flavour of the system to match the task at hand. The ability to adjust the mono/stereo spread ensures that the system integrates even when higher crossover points are used. The LFE input has +10dB sensitivity compared to the main channels, but no built-in lowpass filtering. Unlike the conventional subwoofers, the system is designed to be easy to set-up and intuitive to use.
Pair it with One12, One15, Two15 or One18 for a smaller room full range system or place it with behind the console while keeping your One18, Two15 or Two18 on the meter bridge.
The kit includes: FlexBase25 Tower + FlexAmp1200 (NEW 2U-size integrated amp/crossover) + Cable (single/4-pole).
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.
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.
Variable crossover frequency and bass level attenuator allow the system to match the specific needs of various sound engineering tasks.
Always placed on the center-line of the monitors. Fixed placement and wide adjustment possibilities lead into effortless performance in all rooms.
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.
