Remaining faithful to its mantra of ‘Beautifully Honest’, Amphion once again bucks market trends. This time the Finnish loudspeakers manufacturer reveals an unconventional approach to subwoofer design. FlexBase25 is not a typical subwoofer, but a highly-flexible stereo bass extension and management system with a separate LFE-channel input.
Housed in a single box, this stereo subwoofer is positioned in the centre-line between the main speakers. It offers wide adjustment possibilities over the crossover frequency (35-260 Hz), subwoofer level, and mono-stereo spread. This flexibility allows the user to change the flavour based on the task at hand and ensures an easy integration between the subwoofer and the monitors – even when a higher crossover point is used.
FlexBase25 addresses the needs of the rapidly changing landscape of modern music-making. The subwoofer can be fat, fun, and vibey when writing and producing or precise, correct, and analytical when putting the finishing touches on a song or a film score. With the turn of a few dials, the system can be adapted to what best suits the project an engineer is working on. Unlike conventional subwoofers, the system is designed to be easy to set-up and intuitive to use. The LFE input has +10 dB sensitivity compared to the main channels, but no built-in lowpass filtering.
“A single mono subwoofer is part of a movie format, however, 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,” says Anssi Hyvönen, Founder and Managing Director of Amphion Loudspeakers. “Our FlexBase25 is a new take on the subwoofer design that should fit especially well in the fast-paced modern music-making environment.”
FlexBase25 is a complete system consisting of the subwoofer with two back-to-back 10”/250 mm woofers, and the required cabling and electronics. The subwoofer is powered by Amphion’s FlexAmp500, which also houses the company’s proprietary filter module in its 2U rack enclosure. The system is expected to start shipping in early 2019 at a price of $4,750 / EUR 4,500 (3,750 VAT excluded).
