Established in 1984, R & D Industries, Inc. (RDI) holds its roots in humble beginnings—originally founded to satisfy a case-by-case need for technology and audio engineering across a diverse customer base. Over the last four decades, RDI has grown into a regional leader in professional audio-visual integration—delivering custom sound, video, presentation, and acoustic systems across Iowa, Minnesota, and South Dakota.
RDI uses 3D modeling to help identify and design the ideal AV solution for your environment.
Custom Solutions, Not "Boxed Products"
We believe no single "boxed" product works for every facility. Every space possesses its own unique acoustical and architectural signature. Rather than selling off-the-shelf packages, our certified experts collaborate directly with architects, interior designers, and facility planners during initial project phases.
Using advanced computer-aided modeling tools like EASE and Smaart, we analyze acoustic coverage, speech intelligibility, and sightlines before equipment is ever installed.
Lifelong System Support & Certified Expertise
Our relationship does not end when installation is complete. RDI provides a lifelong partnership to protect your technology investment with our dedicated local services:
RDI Expert Training
Empowering your staff and volunteer teams to operate your sound, video, and control systems with total confidence.
Help Desk & Technical Support
Rapid, local troubleshooting assistance whenever you need a hand.
Routine Maintenance & Repairs
Proactive system checkups and equipment repair services to prevent unexpected downtime.
Long-Term Project Planning
Strategic technical guidance for future technology expansions and facility upgrades.
Industry-Leading Certifications & Partnerships
RDI’s expert team holds top trade credentials—including CTS, Dante, EASE, and Smaart certifications. As a factory-authorized dealer for over 100 top AV manufacturers—including Crestron, Yamaha, Biamp, and JBL—we ensure your technology selection and system integration are always in good hands.
