Anthony Gallo Acoustics A’Diva SE Loudspeakers & TR-3D Subwoofer Review
Set Up and Listening

ImageMy first extended experience with an Anthony Gallo loudspeaker was two years ago, when I reviewed the Classico Cl-1 monitor and matching CLS-10 subwoofer. Having already heard much about Gallo products -- from professional reviewers, dealers, and fiercely loyal owners -- I liked the Classicos very much, but, ironically, they were not the type of speakers Gallo was known for designing. That is, box-shaped monitors. In fact, Anthony Gallo has carved out a distinct and unique position in the speaker market with designs that forgo traditional enclosures and drivers.

Given Gallo’s website -- -- round is exactly the shape that the company is known for. Not to mention Gallo’s unique tweeter design, which unlike conventional designs, do not use a voice coil or magnet. Instead, a transformer passes the signal and contracts the conductive surface of the diaphragm.

Gallo touts round enclosures as superior for a number of reasons:

  • There is one inherent standing wave in every sphere. Gallo controls this largely with its patented S2 Technology.
  • A sphere has no external baffle diffraction to smear the signal.
  • A sphere is the strongest, lightest, lowest mass cabinet possible and has long been known to be the optimal enclosure for a driver. The most important speaker cabinet design factors are structural rigidity and lack of resonance. Box designs attempt to make up for lack of rigidity by adding mass. Mass simply stores energy, which is then released to the environment as harmonics and ringing that are out of time and out of phase with the music. That old familiar "box sound".

A'Diva SEI received a pair of A’Diva SE (Special Edition) monitors, with a TR-3D subwoofer, along with the unique, specially designed stands. A’Diva SEs sell for $329 each. The sub retails for $984.50. Gallo products are available from the web store, and from a brick and mortar dealer network.

The A’Diva SE is five-inches in diameter -- about the size of a large grapefruit -- and weighs about two pounds. The solidly built enclosure is made of a stainless steel material. There are a pair of binding posts on the back that will accept both bananas and spades, however they must be of modest size. Supersized terminations will not work. My review samples arrived in matte black, but matte white, and stainless steel are also available.

According to Gallo, "the Special Edition model utilizes a proprietary ultra-wide dispersion flat-diaphragm transducer that covers a frequency range from 80Hz to 22Khz, all powered by a single driver (meaning no crossover). Then we added Optimized Pulse Technology (OPT) and our patented S2 damping control pods to eliminate all ear-fatiguing colorations, enclosure resonances, and distortions."
