The Focal Sub One Studio Subwoofer delivers tight, detailed low-frequency extension without demanding a huge chunk of studio real estate.
Built around dual 8-inch Slatefiber woofers and 200 watts of Class D amplification, this active studio subwoofer reaches down to 32 Hz while maintaining the precision, dynamics, and low distortion required for critical mixing and production work. Its wide, front-ported cabinet can sit neatly against a wall or beneath a desk, making serious bass monitoring easier to integrate into compact control rooms. Developed to complement Focal Alpha Evo and Shape studio monitors, the Sub One provides comprehensive bass-management controls for smoothly matching the subwoofer to your speakers and room. Adjustable subwoofer level, low-pass frequency, phase, and polarity controls help you dial in a balanced response, while selectable 60 Hz and 90 Hz high-pass filtering lets connected monitors concentrate on the frequencies they reproduce most effectively. Balanced left, right, and LFE connections support stereo and multichannel monitoring configurations, and a footswitch-controlled bypass function makes it easy to compare your mix with and without the subwoofer. Whether you are balancing kick and bass, checking low-frequency effects, or evaluating the full impact of a mastering project, the Sub One delivers the extended range and controlled response needed to make confident decisions.
