Sound, measured twice.
Kestrel was founded in 2012 by two acoustics engineers who were tired of paying for cabinet veneer instead of motor design. Everything we make starts in a chamber, not a mood board.
One target curve, applied everywhere.
All four products are tuned to a single target derived from our own chamber data. That is why a mix approved on the Kestrel One survives the move to the Open and the Studio.
Each production batch is swept unit by unit. The measurement file is stored against the serial number and is available to any owner on request — including second owners.
Four things we do not compromise
Data before opinion
Every design decision is tied to a measurement, and every measurement is published in the product documentation.
Screws, not glue
Drivers, pads, cables and batteries are user-replaceable. A repair should be a workshop visit, not a landfill decision.
Ten years of parts
We hold spares for a decade after a model is discontinued, and publish the service manual for every product we have ever sold.
No burn-in myth
Our drivers are run for 48 hours before measurement. What you hear on day one is what you hear in year five.
“We would rather ship one product that measures well than five that photograph well.”Marcus Yeo · Founder
