Dr Hsu's Craft: Engineering High-Fidelity Bass for 30+ Years
Built By Audiophiles, For Audiophiles
I'd always loved high quality deep bass, but couldn't find what I wanted, even in high-end speaker systems. Motivated to build my own subwoofers that even budget sound enthusiasts could enjoy, I built my first subwoofer while studying at MIT in the '80s. I care a lot about my craft and it's my mission to share the gift of breathtaking sound with all of you!
We do this in 3 ways:
- True Subwoofers
- Speakers
- FREE Guides like the one bellow that help you choose and set up your system (even if you don't purchase from us)

P.S. This is one of the first subwoofers I made out of recycled cardboard. I called it the a sono-tube and it was seven feet tall, taller than me. :)
