Amphion Announces FlexBase25 Speaker Bass Extension And Management System

Amphion Loudspeakers, a Finnish manufacturer of audio monitors, announced FlexBase25, a subwoofer system that is a stereo bass extension and management system with a separate LFE-channel input, which is equally suited for stereo and multichannel applications.

Amphion said the wide adjustment possibilities of FlexBase25 allow the user to change the flavor of the sound based on the task at hand. FlexBase25’s crossover frequency can be adjusted within a wide range of 35-260 Hz. The ability to control the mono/stereo spread ensures that the sub integrates with the monitors even when a higher crossover point is used.

Unlike 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.

“A single mono subwoofer is part of a movie format, but we do not believe that it is good enough to be used in music production. In order to create correct imaging the stereo information needs to be maintained throughout the whole frequency band. Our FlexBase25 is a new take on the subwoofer design that should fit especially well with the rapidly changing landscape of modern music-making.”
Anssi Hyvönen, founder and managing director of Amphion Loudspeakers.

FlexBase25 is a complete system consisting of the subwoofer with two back-to-back 10-inch woofers and required cabling and electronics. The subwoofer is powered by Amphion FlexAmp500, which also houses the company's proprietary filter module in its 2U rack enclosure.

The system will start shipping during the third quarter of 2018. Price still to be announced.
