Hi, I’m Curt Campbell.
For over twenty years I’ve been sharing fully documented loudspeaker designs here at Speaker Design Works, free for personal, non-commercial use. Designs like the Statements, Statement II, Uluwatu, Anthologys, Singularities and others have found their way into listening rooms around the world, and it’s been a real privilege to see people build and enjoy them.
Keeping this site going does cost money. Website hosting, measurement gear, drivers and components for testing, and the time spent measuring, listening, and refining all add up. Any support you can offer helps offset those expenses so I can keep developing new projects and making the documentation available.
If you’ve built one of these speakers, found the write-ups useful, or simply appreciate the work, buying me a coffee is a kind way to help keep things running. Thank you, it means a lot.
