Gallo hi-fi system - A'Diva, Due and Micro speakers with MPS 150 powered subwoofer

Gallo's heritage - In the beginning

Anthony Gallo designed his first loudspeaker at the age of fourteen. His first commercially available product - the Nucleus reference speaker (right), went on sale in 1994. Today, his Nucleus Micro, A'Diva and Dué loudspeakers are sold in over 40 countries.

Anthony Gallo was born in 1963 and from an early age he had an interest in the sciences and would take apart just about everything he could get his hands on. At around age 13, he began to become hooked on loudspeaker design. His first experiments were with electrostatics at age 14! "Absolutely, I got shocked a zillion times, I was always awed by their transparency and purity. The dynamics however were always short of my expectations."

Anthony then moved on to working with ribbons." I took apart an old radar tube called a magnetron. A magnetron has about thirty pounds of Alnico V. After removing this huge magnet I started using it as the basic magnetic circuit for my ribbon designs". Once again he was hooked on their speed and transparency but "they were very hard to drive and limited in dynamic range, not to mention the myriad of cavitational resonance's created by the pole pieces and various reflective distortions. By that point I was determined to continue on my search for the Holy Grail of tweeters. I started buying every dome available in the US but none even came close to satisfying me".

Then, in the early 1980's an electronics magazine issued an article talking about the uses of Piezo film and the potential for audio applications. "I threw the magazine aside for a few years but in the back of my mind I knew that I would some day work with this material." In 1987 the first version of the CDT™ (cylindrical diaphragm transducer) was born. It took nine years of research and development to get the CDT™ to its current status. During that time Anthony worked for Panasonic where he was a commercial video engineer. He also started and ran a thriving video repair business, "I ended up selling the business along with my cars and everything else I owned to continue research on the Nucleus and various patent expenses."
