Understanding the electronics, physics, and design elements that shape a hifi speaker
Upon deciding to embark on the journey of building a speaker, I knew I had a large task ahead of me. This project involved everything from research to design and fabrication of a speaker. Over the course of this project, I was able to apply my theoretical knowledge of electronics and newly learned technical knowledge to successfully create a functioning speaker. Additionally, I learned a lot about the aspects of science and math that go into the acoustic design of a speaker. Everything from volume, materials, speaker location, and even the weather can have a difference on the sonic qualities of a speaker. Attempting to combine all these variables into one successful speaker design is something that can take years to grasp, so I have hardly scratched the surface of these topics. I did however gain enough knowledge to confidently adjust an existing speakers characteristics to fit what I was looking for. Using a design by Alexander Gresler as inspiration, I was able to collaborate with my long time friend Grant Kilgard (UC Industrial Design Class of 2026) to modify the physical aspects of the speaker. Drawing design inspiration from natural and organic forms, we developed a speaker cabinet with sides that flow into each other seamlessly. The fabrication step of this project is still a work in progress due to extensive materials research and experimentation. Along the way I corresponded with my mentor to discuss potential design flaws and ways to push the boundary of what was possible for this project. In the end, I gained an immense amount of knowledge on the design and fabrication of speakers and can confidently say this is only the beginning of my journey in building hifi speakers. I am in the process of sourcing materials for a second pair of speakers based on how enjoyable this first project has been. I hope to be able to use my newly acquired knowledge and experience to further develop this personal project and potentially professional projects in the future.
Shown here is a timelapse video of myself assembling one of the speaker crossovers based on a schematic. Prior to this project, I had no previous experience using the majority of the components shown in the video. I gained an immense amount of theoretical knowledge about how to translate a circuit schematic into a physical circuit. I also learned a great amount about proper technique and safe ways to work with the materials I was using.
