The Criton Series
The kit story
Yours, from the first screw to the final note.
Every Criton begins the same way: matched drivers, a hand-tuned crossover, cabinet-grade materials — delivered to your door. What happens next is up to you. Build it over a weekend, finish it in any veneer you can dream of, and live with a speaker that carries your fingerprints.


Measured, not marketed
No mysticism. No snake oil. Just engineering.
High-end audio is full of beliefs that aren't backed by science. We take the opposite path: proven theory, countless hours of driver testing, and acoustic evaluation behind every decision. We never sell what we wouldn't buy ourselves.
