Introducing Theia Passive & Rhea Passive
New Icons of Design and Sound
Grounded in Excellence
Goldmund proudly unveils Theia Passive and Rhea Passive, two exquisite passive stereo speakers that embody the iconic design language of Goldmund’s latest active speaker collection. Seamlessly merging timeless elegance with acoustic excellence, these new additions set a benchmark for both form and function.
A SONIC Sculpture
The first thing that captivates is their striking presence. The Theia Passive and Rhea Passive integrate effortlessly into any environment, their sleek, sculptural forms radiating refined sophistication. Every detail has been meticulously considered, ensuring these speakers transcend their role as audio devices to become true works of art.
Excellence Carved Into Every Line
Goldmund’s dedication to precision is evident in every aspect of construction. The cabinets are assembled with invisible seams, achieving a flawless, uninterrupted finish. Each panel is joined at a precise 45° angle, creating a seamless fusion between the grid and aluminum structure. Wavy side panels interact with light, adding depth and dynamism, while the dual-finish aluminum exterior—micro-blasted on vertical surfaces and brushed on horizontal panels—further enhances their architectural presence. The standard finish features an elegant gray body with black grids, though a black version is available upon request, subject to stock availability.
Unshakable Precision
Handcrafted with meticulous attention to detail, each speaker reflects Goldmund’s uncompromising standards. Theia Passive and Rhea Passive’s substantial mass, combined with Goldmund’s proprietary mechanical grounding construction where a tip crosses the speakers directing spurious vibrations to the ground, ensures absolute purity in sound reproduction.
The Science Behind the Sound
Beneath the elegant exterior lies an expertly engineered acoustic landscape. The speakers were modeled using Proteus LS, Goldmund’s proprietary software, which meticulously calculates system impedance, volume velocity, membrane displacement, and sound pressure. The result? Astonishing accuracy, clarity, and a coherent soundstage that immerses listeners in a truly breathtaking auditory experience.
Every Note, Every Nuance—Flawless
Theia Passive is a four-way passive speaker, while Rhea Passive is a three-way passive stereo speaker, both meticulously crafted to redefine sonic realism. Every component—from the precision drivers to the finely tuned cabinet—has been optimized for extraordinary performance. Their state-of-the-art drivers deliver a wide frequency response and an exceptional dynamic range, faithfully reproducing every nuance and emotion in the music.
Hear the Unimaginable
Advanced crossover technology ensures seamless frequency integration, creating an expansive and immersive soundstage with impeccable balance and dispersion. Each driver is equipped with a fully custom independent crossover board. We use only the highest-quality components, including MKP capacitors and non-inductive film resistors thermally managed with custom-designed heat sinks.
Pushing Passive to the Peak
Our free air-core inductors, crafted from ultra-thick, pure oxygen-free copper, ensure exceptional linearity and minimal distortion. To avoid vibrations, Goldmund employs a precision-engineered combination of PCB boards and mechanical mounting techniques for these inductors. All passive components are designed with power ranges several times greater than the actual power they handle, ensuring that voltage or current transients never cause saturation.
Unleash Their Full Potential
We are among the only companies making such significant resource investments in the design and refinement of these high-performance components. This meticulous approach results in an unparalleled listening experience from our passive speakers. To extract the finest performance from these passive speakers, high-end amplification is essential. Theia Passive and Rhea Passive support three configurations: Mono-Amplification; Bi-Amping; Tri-Amping.
Mastering the Art of Sound
This flexibility allows audiophiles to tailor their setup for optimal sound. Pairing these speakers with high-slew rate, high-dynamic-range amplifiers is critical— low slew rate amplifiers may struggle to command their ultra-fast drivers, resulting in diminished control and fidelity. To preserve every detail, transient, and dynamic shift, premium loudspeaker cables are strongly recommended.
Timeless Form, Future Sound
Designed for those who cherish analogue systems, the Theia Passive and Rhea Passive bring a contemporary upgrade to traditional setups. Their refined aesthetic and unparalleled transparency transform any listening space into a gallery of sound and style.
With the Theia Passive and Rhea Passive, Goldmund continues its legacy of craftsmanship and uncompromising sonic excellence. Prepare to embark on a journey where every note and nuance transcends the boundaries of imagination.
