World class engineering. Affordable pricing. Dependable customer service. With engineering advice from industry leading transducer designers Patrick Turnmire of Redrock Acoustics and Enrique Stiles of STEP Technologies DSS transducers undergo a strenuous development process to ensure each design goal is met. Product is first designed using the latest version of the industry’s standard in driver modeling software, SpeaD 3.0. Product samples are then put through rigorous testing by Turnmire via a Klippel analyzer to extrapolate small and large Thiele/Small parameters and to insure no anomalies need to be addressed. Once production parts are built they are sent to our supply house in Killen, Alabama where parts are, inspected, and motors are charge. They are then freighted to our warehouse in Folsom, Louisiana where they are hand assembled, inspected, and packaged.
