Best High End Speakers

Anthony Gallo was instrumental in creating the proprietary, critically acclaimed CDTII™ (cylindrical diaphragm transducer) tweeter, as well as the company's S2 technology. These two innovations in speaker design, coupled with the company's use of spherical shapes, have fueled the company’s success and defined the unique sound of its products. Read on below to learn how these elements work together to create the ultimate stereo or home theater sound system.

Perhaps Anthony Gallo’s crowning achievement, the patented CDTII™ tweeter (used in the Reference 3 loudspeaker) builds on the renowned CDT™ tweeter to reach new highs in high frequencies. The CDTII™ is made up of a diaphragm membrane fashioned from Kynar™, a cutting-edge aerospace plastic. This diaphragm is then polarized with pure silver because of its high conductivity and reliability, to which high-quality, oxygen-free copper wires are attached. Finally, the diaphragm assembly is tightly wrapped around a rigid compliant core with a perforated steel center. This inner core acts as attenuation for the driver's backwave and provides restorative force.

Unlike conventional drivers, the CDTII™ doesn't use voice coils or magnets. Instead, a matching transformer passes the signal across and contracts the conductive surface of the diaphragm, which expands the CDTII™, allowing cylindrical radiation patterns. The result is unparalleled high-frequency performance. S2 Technology.

Anthony Gallo’s patented S2 technology is just one of the proprietary elements that helps to provide our speakers with unrivaled sound. Employed in all of our loudspeaker products, S2 technology extends low-frequency response much lower than would otherwise be possible in speakers of a given size. Hear the Sphere.

Since our inception, Anthony Gallo's trademark has been the use of a spherical enclosure in our speaker designs. The Nucleus Solo, our first loudspeaker design, began as a solid aluminum disc which was then spun into a hollow 12" ball. The spheres were then placed in an electrolytic bath, which forms a hard shell that actually bonds to become part of the metal. This anodizing process gives our enclosures the mechanical properties of ceramic, which is one of the most acoustically inert materials on earth.

This combination of spherical geometry and anodized aluminum construction made this enclosure virtually free of resonance and diffraction. Similarly, the properties of heat-treated and powder-coated steel give the smaller, 4" Nucleus Micro™ the same enclosure characteristics.
