I am a structural and chemical engineer as well as a master furniture maker. I test and certify all designs and prototypes including acoustical testing of all product components from our foam to our activated carbon. My structural engineering focus is on our cabinet designs for our ACDA series of low frequency absorbers. I also assist in designing and testing the multiple layer, cabinet construction to reduce vibrations in the cabinet structure and encourage vibrations on the front, dual wall, construction technique to increase absorption rates and levels.
