Description Gallo Acoustics Micro / A’Diva Wall Mount Gallo Acoustics Micro / A’Diva Wall Mount for Micro and A’Diva loudspeakers, including SE variants. There are numerous loudspeakers capable of producing fine sound, unfortunately most are too large, unattractive or power hungry to operate in many modern living spaces. That’s what makes the Gallo Acoustics speakers different: a 4″ diameter all-metal sphere, available in a wide range of colours and finishes The micro loudspeaker range has long been the audiophile’s choice in the ‘compact’ speaker category, whether for two-channel music, home cinema or multi-room audio. A 4” all-metal sphere capable of producing a large sound stage and pinpoint imaging, delivered in a beautifully-compact, timeless form factor. By choosing a sphere, the strongest possible shape, we have eliminated internal resonance and external diffraction, the two main causes of loudspeaker distortion. Our patented S2 fill technology enhances low frequencies that go way beyond conventional satellite speakers.
