The FlexBase25 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. Unlike the conventional subwoofers, the system is designed to be easy to set-up and intuitive to use.
The LFE input has +10dB sensitivity compared to the main channels, but no built-in lowpass filtering. The LFE channel can be linked between several units which then allows building 7.1 and upward systems.
