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!

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 :)

Budget systems aren’t supposed to be able to attain this kind of dynamic range and still maintain their composure? They do now.

HSU is the most overlooked brand in-home theater. I doubt I will ever buy a sub from any other brand.

I'm willing to bet you've never heard a speaker this size sound this good... the results achieved are incredible. Great products, great company, great value. What else is there to say?

Home Theater Shack

HSU subs are the bomb! If I am in the market for a sub, I am buying HSU again. Especially for the money, I don’t think any sub can touch it.


The company's reputation of
delivering subwoofers with the most "bang for the buck" is legendary in the world of Consumer Electronics.

There is no subwoofer products that definitive technology makes that I would take over anything that HSU makes.

Love [HSU Subs]. Have one I'm listening to right now. :) GORGEOUS, big, powerful. Easy to set up.


I have had numerous people from all walks of life over to EXPERIENCE the sound that my home theater is now capable of producing and I have heard time and time again from them that I HAVE NEVER HEARD ANYTHING LIKE THAT BEFORE.


Went from no sub to a Hsu MK5 VTF-3. I went from walking to work to riding a Lamborghini.

The HB-1 MK2's soundstage is stunning and better in my room than even my reference Bowers & Wilkins.

Home Theater Review

The amount of value you’re getting cannot be understated. The HSU Research CCB-8s are dynamic monsters and image better than some much pricier speakers I’ve heard.

Audio Bacon

I am not sure why your bookshelves are so much more musical than many of the other speakers on the market today. And to think that some of these speakers are over 80 times the price of yours!


The VTF-15H delivered the most bang for the buck of any subwoofer on the market.
