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:

  1. True Subwoofers
  2. Speakers
  3. 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. :)
