By default, all speaker measurement profiles will be stored as .swproj files in the Sonarworks Projects folder. The Sonarworks Projects is located in:
C:\Users\your_username\AppData\Local\Sonarworks\Reference 4\Sonarworks Projects
/Macintosh HD/your_username/Username/Library/Sonarworks/Reference 4/Sonarworks Projects
After you find the needed profile, you can copy it and transfer it just like any other computer file.
