We turned a customer's returned DIY speaker into a $10,000-level build. Here’s what it actually takes to push a speaker from basic to truly high-end.
What happens when you take a customer's returned DIY speaker and go completely over the top?
In this video, we transform a rough-looking speaker kit built by one of our customers into a stunning, high-end build that rivals $10,000 systems. From cabinet redesign to a full crossover overhaul, we push this build far beyond what was originally intended.
We upgrade the cabinet with hardwood side panels, large roundovers, chamfers, and premium finishes—then take it even further with a beryllium tweeter and a completely redesigned crossover.
Along the way, we break down the key principles that separate average DIY speakers from truly high-end performance, including measurements, crossover design, and cabinet finishing techniques.
If you're into DIY audio, speaker building, woodworking, or high-end audio design, this video will show you what it really takes.

-CSS took that personally!
-CSS builds epic, over the top custom with returned speaker.
I LOVE IT!
(And I love my Criton 1TDX!!)
Thank you for taking time out of your day to demo these great speakers. The vinyl wrap was so nice I didn’t know it was vinyl until I rewatched this video. The look is clean and refined and cabinet looked expensive (in a good way!). Outstanding build quality! Loved the definition and the detailed sound and my daughter’s new album sounded as open and airy as it was mixed in the studio. I was surprised the sound was as full as it was for bookshelf speakers and you both have fantastic catalog of speakers at very reasonable prices. Not an easy accomplishment! So glad I could meet you as part of my Michigan visit as I used to live 10 minutes from your location in the 1980s. So great to know some great Michiganders are helping to lead speaker design in 2026. To anyone reading this, I’m sure most of the community is aware of the quality speakers that Dan and Cary deliver, but if you haven’t had the pleasure to hear them, I highly recommend them.
Thanks again Dan and Cary!
