Gallo Acoustics

THINKING DIFFERENTLY

Gallo Acoustics don’t produce ordinary speakers, they don’t make boxy designs in their line-up simply because they believe there’s a better way.
With over 20 years of spherical loudspeaker design, the award winning Gallo Acoustic Speakers are designed around spheres, eliminating resonance and internal diffraction, the two main causes of loudspeaker distortion.
At Gallo Acoustics they produce some of the world’s finest compact speaker systems, blending hi-fi performance and contemporary industrial design, wrapped them all up in an installation and decor-friendly package, and importantly guarantee exceptional, expansive sound to spaces large and small.

DESIGN AND TECHNOLOGIES

Spherical Design: Since inception Gallo’s trademark has been the use of a spherical enclosures in their speaker designs. The Nucleus Solo, their first loudspeaker design, began as a solid aluminium disc which was then spun into a hollow 12″ ball. The spheres were then placed in an electrolytic bath, which formed a hard shell that actually bonded to the metal. This anodising process give their enclosures the mechanical properties of a ceramic, one of the most acoustically inert materials on earth. This combination of spherical geometry and anodised aluminium construction made this enclosure virtually free of resonance and diffraction, the two main causes of loudspeaker distortion. Similarly, the properties of heat-treated and powder-coated steel give their smaller, 4″ Micro and 5″ A’Diva loudspeakers the same enclosure characteristics.

S2 Technology: Employed in all of their loudspeaker products, their proprietary S2 technology extends low frequency response two full octaves lower than would otherwise be possible in relation to the speaker’s size. S2 technology improves ‘Volumetric Efficiency’ – in other words, how the speaker’s drivers perceive the size of their enclosure. Normally a speaker’s volumetric efficiency is between 1 and 2, their S2 technology gives us a rating of 10. This means that their speakers operate as if their enclosure was 10 times its actual size.

CDT: Gallo Acoustic’s patented CDT technology, as employed in their Strada 2 model, is made up of a diaphragm membrane made of Kynar™, a cutting-edge aerospace plastic. This diaphragm is then coated with pure silver because of its high conductivity and reliability, next they silver solder high quality, oxygen-free copper wires to each end of the diaphragm. Finally, the diaphragm assembly is tightly wrapped around a rigid polypropylene core. This inner core acts as attenuation for the driver’s back-wave. Unlike conventional drivers, the CDT doesn’t use voice coils or magnets, instead the signal is passed across the conductive surface of the diaphragm, which attempts to expand, while the shape of the driver supplies the necessary restorative forces.
