INTUITIVE
Focus on design, not complexity.
A speaker enclosure design tool that brings design, comparison, and listening into one flow.
ABOUT SFR
Design and analysis tools for thinking, testing, and comparing—starting with sound.
Speaker design has long lacked tools that let people intuitively simulate a range of enclosure configurations and compare them in one continuous workflow. SFR | SONIC FLOW RESEARCH was created to address that gap.
Instead of spending time on complex operations or calculations themselves, designers can choose a driver and enclosure, adjust conditions, and validate the result as they work. Compare the graphs, hear the difference with your own audio, and stay focused on design decisions.
Starting with the knowledge developed through acoustic design, we will extend these tools beyond sound—toward designing and testing flow, connections, and systems. SFR will keep expanding practical tools in which every step and every piece of information connects naturally.
