INTUITIVE
Focus on design, not complexity.
Enclosure and network design. Listen, adjust, and compare.
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.

ENCLOSURE DESIGN
Listen with your audio, LF or full-range sweeps, and pink noise. Your audio, playback position, playback state, loop and volume stay with you across design views.
Design enclosures and networks from 1way to multi-way, using response graphs and shared listening controls for your audio or test signals.
430 speaker drivers
Current and legacy drivers and tweeters. Available specifications and design data vary by unit.
Eight enclosure configurations
Explore different enclosure configurations and compare the results as you design.
