Redrock Acoustics was started in 1985 to provide loudspeaker technical information to the Car Audio industry. In 1989 Redrock Acoustics became engineering consultants to the well known Chinese factory Sonavox (Now probably the highest volume speaker manufacturer in the world). The huge number of new speaker designs (100’s per year) that Sonavox needed, gave birth to the idea of SpeaD Loudspeaker Design software.

SpeaD was born of a combination of incredibly complex mathematical models and literally thousands of speaker samples to fine tune those models. During long months and years at the Sonavox factory, Patrick wrote and polished the Software until it was able to accurately predict Thiele Small parameters and produce a complete speaker design in a few minutes.

In the 22 years since Redrock’s beginning, it has been responsible for over 1600 successful loudspeakers products that made it to market. These products have won more than 20 industry awards including 11 Design and Engineering award, several GrandPrix awards and numerous top reviews in respected audio publications.
