Anthony Gallo Acoustics Nucleus Speakers (Set of 5, Silver) – Pre-Owned

The Anthony Gallo Nucleus Micro set the benchmark for compact audiophile design. By replacing traditional boxy speaker cabinets with rigid, spherical steel enclosures, Gallo completely eliminated internal standing waves and edge diffraction—two major culprits of acoustic distortion.

Whether set up as a discreet 5-channel surround sound system for a home theater or utilized across stereo/multi-room zones, these satellites produce an expansive, transparent soundstage with smooth, fatigue-free highs and remarkably clear midrange clarity. Pair them with a powered subwoofer for a seamless, full-range listening experience.

Key Features

• Acoustically Inert Spherical Enclosures: 4-inch spun steel spheres virtually eliminate internal resonance and boxy coloration.

• Point-Source Imaging: The custom-engineered 3-inch full-range driver provides pinpoint spatial localization and wide, room-filling dispersion.

• Compact & Minimalist: Blends effortlessly into modern living rooms, studios, or dedicated media setups without visual clutter.

• Flexible Placement: Compact footprint allows for easy placement on shelves, media consoles, or custom wall/table mounts.

Condition & Working Order

• Cosmetics: Good Vintage / Pre-Owned Condition. The metal shells and mesh grilles show minor cosmetic signs of handling and age consistent with pre-owned gear (please refer to photos for exact visual condition).
