The Amphion FlexBase25 is a stereo bass-extension and management system with a separate LFE-channel input and 2 x 300 W 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 should fit especially well with the rapidly changing landscape of modern music-making and will satisfy even the most demanding producers or sound engineers.

FlexBase is a single box, stereo subwoofer, which is placed in the centre line between the main speakers. Wide adjustment possibilities over crossover frequency (35-260 Hz), subwoofer level, as well as the mono-stereo spread, allow FlexBase to address the needs of a rapidly changing landscape of modern music-making. With a turn of a few dials, the system can be adapted to what best works for the project an engineer is working on.

FlexBase can be fat, fun, and vibey when writing and producing. It will be precise, correct, and analytical when putting the finishing touches on a song or a film score. The system will allow you to continue to use your monitors for a narrower midrange view, as FlexBase can be bypassed. FlexBase works with all Amphion products. 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.
