GoldenEar SuperSat 3

The GoldenEar SuperSat 3 embodies a unique approach to high-definition sound reproduction in a surprisingly compact format. Weighing just 2.3 kg, this satellite speaker combines cutting-edge technologies with sophisticated construction to deliver acoustic performance that seems to defy the laws of physics.

A folded ribbon tweeter that compresses air rather than pushing it

At the heart of the SuperSat 3 is the HVFR (High Velocity Folded Ribbon) tweeter, a modern variation of the air motion transformer invented by Oscar Heil. This technology fundamentally sets the SuperSat 3 apart from conventional speakers. Instead of using a rigid dome that pushes air like a piston, the HVFR tweeter employs an accordion-folded diaphragm made of a high-temperature film positioned within a powerful neodymium magnetic field.

The operating principle is based on compressing air between the folds of the diaphragm. When the electrical signal passes through the conductive diaphragm, the folds alternately contract and expand, creating zones of high and low pressure that generate sound waves. This method of propagation achieves superior impedance matching with the surrounding air, resulting in greater control, a more linear and extended response up to 35 kHz, and significantly reduced distortion.

The total surface area of the folded diaphragm, when unfolded, far exceeds that of a traditional dome tweeter of equivalent size. This feature allows the HVFR to move a substantial volume of air with minimal movement, thereby reducing nonlinear distortions while enhancing dynamics and power handling.

D’Appolito configuration and MVPP technology: a calculated acoustic synergy

The two 115 mm mid/bass drivers flank the HVFR tweeter in a D’Appolito configuration—named after engineer Joseph D’Appolito, who theorized this arrangement in the 1980s. This MTM (midrange-tweeter-midrange) architecture is not merely aesthetic: it creates a vertically symmetrical acoustic source centered on the tweeter axis.

Each mid/bass transducer incorporates proprietary MVPP (Multi-Vaned Phase Plug) technology. These multi-vaned phase plugs, positioned at the center of the cones, serve several crucial functions. They control the energy radiated from the center of the cone, minimizing destructive interference caused by waves propagating from different parts of the diaphragm. The vanes of the phase plug act as miniature waveguides, channeling and linearizing acoustic propagation.

The cast-basket frames of the drivers provide exceptional rigidity while minimizing unwanted internal reflections. This construction allows the computer-optimized cones to maintain pistonic behavior over a wide bandwidth, extending well beyond their 3.5 kHz crossover frequency. This controlled extension into the high frequencies facilitates seamless integration with the HVFR tweeter.

Marble powder-infused polymer enclosure: the alliance of form and function

The SuperSat 3’s cabinet transcends the role of a mere protective shell to become an integral acoustic element. Made from a polymer infused with marble powder, this composite material exhibits unique vibrational properties. The marble powder significantly increases the density and rigidity of the polymer while altering its internal damping characteristics.

The dimensions of 121 × 305 × 70 mm are not arbitrary. The elegantly curved shape of the enclosure, beyond its visual appeal, minimizes internal standing waves. The absence of large parallel surfaces prevents the formation of pronounced resonances that would color the reproduced signal. The piano black lacquer finish, achieved through a multi-layer polishing process, adds an extra layer of surface rigidity.

The acoustic suspension (sealed box) design eliminates the issues of overhang and resonances associated with bass-reflex ports. This approach ensures a fast and precise impulse response, particularly beneficial for transient reproduction and spatial localization. The carefully calculated internal volume loads the mid/bass drivers optimally, allowing controlled extension down to 80 Hz despite the compact dimensions.

Installation versatility and system integration

The SuperSat 3 was designed from the outset to adapt to a multitude of configurations. The included desktop stand allows stable shelf placement with an optimized tilt to direct sound toward the listening area. Threaded inserts and keyhole slots offer options for flush or angled wall mounting via the optional SuperSwivel bracket.

For more ambitious setups, the SuperStand floor stands transform these compact satellites into sleek column speakers with a total height of 1.17 meters. This flexibility allows the SuperSat 3 to adapt to changing needs and living spaces without compromising acoustic performance.

The nominal impedance of 4 ohms (8-ohm compatible) and sensitivity of 92 dB reflect an optimized electroacoustic design. These features allow comfortable sound levels with modest 20-watt amplifiers, while also supporting powerful amplifiers up to 200 watts for the most demanding applications. The gold-plated binding posts accept a variety of terminations, from bare wire to dual banana plugs.
