CEO & PRESIDENT

Jeff Francisco

"Innovator of Architectural Audio"

Jeff Francisco’s interest in music started at a young age when he became a musician. His interest and abilities grew to the point he received a degree in music performance and became a professional musician and composer in the Los Angeles music scene playing and recording with a wide variety of classical, jazz, and pop music artists.

In 1985, Jeff joined SpeakerCraft and got an engineering education from the ground up in loudspeaker design, R&D, and manufacturing. He oversaw the development of the world’s first custom home installed speakers for now legendary brands. Shortly after the SpeakerCraft brand of architectural speakers was launched Jeff took over R&D responsibilities. He oversaw the successful introduction of hundreds of speaker and electronic products. He holds loudspeaker patents and introduced many new technologies to the industry.

In 2012, Jeff became CEO & President of The DaVinci Group – TDG Audio. He brought with him not only his engineering expertise but also his passion for music. His uncompromising approach to the best possible music reproduction is something he learned in recording studios and applies to every product he designs at TDG.

CTO & FOUNDER

Alex Chiou

Alex began his career with one of Asia’s premier loudspeaker manufacturers, working with many of the world’s well-known brands in consumer, commercial and custom integration channels. He methodically learned and mastered every aspect important to the design and engineering of loudspeakers and became a valued asset to not only the company but its many customers.

Alex later moved on to manage loudspeaker development at SpeakerCraft and was key to the development and manufacturing of dozens of products. Alex’s incredible understanding of all aspects of loudspeaker engineering and manufacturing and his “hands-on” attitude likely make him the industries only CTO that is genuinely involved in even the smallest details of loudspeaker manufacturing.
