A local yoga and meditation studio needed a sound system. Not a home stereo slapped on the wall — a properly designed, installed, and tuned audio system for a specific room with specific acoustic characteristics and a specific use case: ambient music and guided instruction that fills the space evenly without being loud in some spots and absent in others. The project involved speaker selection, placement modeling, installation, and acoustic tuning. It’s the kind of favor that turns into a real engineering project once you start caring about doing it right.
