Overview

Timeless elegance

Goldmund unveils the Theia Passive, a stunning passive stereo speaker inspired by the iconic design of the Theia active wireless speaker. Combining timeless elegance with acoustic excellence, this new addition to Goldmund’s prestigious lineup sets a new standard for both form and function.

Sculpted for the Senses

The first thing to captivate you is the Theia Passive’s striking aesthetics. This loudspeaker seamlessly integrates into any environment, embodying sophistication with its sleek, sculptural form. Every detail has been meticulously considered to ensure that the Theia Passive is not just an exceptional audio device but a true work of art.

Legacy in Every Note

Goldmund’s commitment to precision is evident in the construction of its cabinets. The panels are invisibly assembled, achieving a clean and flawless finish. Each part is joined at a precise 45° angle, creating a seamless structure where the grid and aluminum speaker cabinet form a single entity. The cabinets feature wavy side panels that play with light and a dual-finish aluminum exterior: micro-blasted on vertical surfaces and brushed on horizontal panels. This interplay of textures and light adds a dynamic visual depth, while the elegant gray body and black grids exude understated sophistication.

Every Detail, Every Decibel

Every Theia Passive speaker is meticulously handcrafted by Goldmund’s artisans, ensuring unrivaled attention to detail. The finest materials are selected, and rigorous quality control processes ensure that each unit meets Goldmund’s uncompromising standards. Weighing over 260 kg per unit, its substantial mass combined with Goldmund’s proprietary mechanical grounding construction principles eliminate spurious vibrations, preserving the purity of sound reproduction.

Listen Beyond the Notes

Beneath its captivating exterior lies a meticulously engineered soundscape. Every component, from the precision drivers to the expertly tuned cabinet, has been carefully optimized for unparalleled audio performance. The Theia Passive is modeled using Proteus LS, Goldmund’s proprietary software, which ensures precise calculations of system impedance, volume velocity, membrane displacement, and sound pressure. This cutting-edge technology results in astonishing accuracy, clarity, and a coherent soundstage that immerses listeners in an extraordinary audio experience.

Engineered for the Ear

A true four-way masterpiece, Theia Passive is engineered to redefine sonic realism. Its state-of-the-art drivers deliver a wide frequency response and exceptional dynamic range, faithfully reproducing every subtle nuance and emotion in the music. Advanced crossover technology ensures seamless frequency integration, resulting in an expansive, immersive soundscape 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.

A force of nature

Our free air-core inductors, crafted from ultra-thick, pure 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. 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.

The fusion of art and audio

To unleash Theia Passive’s full potential, the use of high-end amplification is essential. The speaker supports three amplifier configurations: Mono-Amplification, Bi-Amping, and Tri-Amping, providing flexibility for audiophiles seeking the ultimate setup. However, it is crucial to pair Theia Passive with high-speed, high-dynamic-range amplifiers—as slower, less responsive units may struggle to command its ultra-fast drivers, resulting in a loss of control and sonic fidelity. For optimal performance, we also recommend high-quality loudspeaker cables, ensuring every detail, transient, and dynamic shift is delivered with absolute precision.

A masterpiece that speaks volumes

Designed for those who cherish analogue systems and seek a modern upgrade, the Theia Passive enhances traditional analogue audio setups with its minimalist design and exquisite transparency in sound reproduction. Its refined aesthetic and exceptional performance transform your listening space into a gallery of sound and style. The Theia Passive embodies Goldmund’s legacy of craftsmanship, innovation, and an unwavering commitment to delivering lifelike audio. Prepare to embark on a sonic journey where every note and detail transcends the boundaries of your imagination.
