About Adire Audio

Adire Audio started as a dream to build the biggest, baddest transducers on the planet.  I like to think we delivered, and we fundamentally changed the way transducers were designed and built because of it.  As it closed down in 2008, the team moved on to other things, different industries.  I myself went hard-core into consulting and along the way designed transducers in the pro, consumer, and automotive space that ship in the tens of millions a years.  XBL^2 not only brought concepts like linearity and accuracy to the lexicon, it also set a standard for high-performance reproduction.

A year or so ago, I was approached by two audio enthusiasts who had the same passion for audio that the Adire team did, back in the late 90s/early 2000s.  In talks over the last year, it’s become painfully obvious to me that not only do I not have the heart or desire to get back into the DIY/automotive transducer market directly, but that I had, in fact, found two individuals who could carry forward what we created and grew.  Kindred spirits who see life in audio not as a balance sheet or marketing campaign but a way to let thousands and thousands of people experience music.

It is with great pleasure that I “hand over the torch” to Andrew and Brandon.  Through our talks and meetings, I’ve come to realize they will carry forward the original vision and goals of Adire Audio, and ensure it will grow and move and continue to influence the direction the hobbyist/automotive market moves.  It is highly rewarding to know that people who used our gear back in the day, want to see it not just come back to life, but continue growing along the same path and principles.  I can think of no better people to do this than Andrew and Brandon.
