Goldmund Prana Active Stereo Loudspeakers

The Goldmund Prana is a three-way active floorstanding loudspeaker system combining 600 watts of built-in Telos amplification per speaker, Goldmund DSP, Leonardo time correction, Proteus LS acoustic modeling, wireless connectivity and Mechanical Grounding in one of the Swiss manufacturer's most recognizable sculptural designs. Each Prana contains its own amplification and digital processing, eliminating the need for conventional external power amplifiers and passive crossover networks. Goldmund

Derived from Goldmund's legendary Apologue design lineage, Prana uses two substantial aluminum enclosures suspended within a precision-engineered metallic frame. Behind that architecture is a fully active system with a soft-dome tweeter, 7-inch midrange driver and 9-inch woofer, each controlled by dedicated Telos amplification and DSP optimized specifically for the loudspeaker. Goldmund

Fully Active 3-Way Architecture

Prana is a true three-way active loudspeaker. Each speaker contains:

1 × soft-dome tweeter
1 × 7-inch midrange driver
1 × 9-inch woofer

Unlike a conventional passive speaker, Prana does not rely on a single external amplifier feeding a passive crossover. Goldmund's DSP performs the crossover and signal optimization digitally, while dedicated amplifier channels directly control the individual drive units. Goldmund

This architecture allows Goldmund to optimize crossover behavior, gain, delay and phase alignment for the exact drivers and enclosure rather than leaving those relationships dependent on an external amplifier and passive component network.

600 Watts of Built-In Goldmund Telos Amplification

Each Prana incorporates 600 watts of Goldmund Telos Class A/B amplification.

The power is distributed as:

Because the amplification is integrated into the loudspeaker and engineered around the specific drivers it controls, Prana removes the uncertainty of matching a conventional speaker with an external power amplifier.

Goldmund's Telos technology uses high-bandwidth Class A/B circuitry and highly linear analog components, with the objective of maintaining precise control of driver movement while reducing time and intermodulation distortion. Goldmund

Goldmund Digital Signal Processing

DSP is fundamental to Prana's architecture rather than an added feature.

Goldmund uses digital processing to implement the loudspeaker's:

Digital crossovers for frequency division
Gain optimization for the individual drivers
Delay optimization for alignment
Leonardo Time Correction for phase correction Goldmund

Goldmund's active architecture replaces conventional physical crossover filtering with software-based processing, allowing the behavior of the drivers to be controlled with considerably greater precision. Goldmund

Leonardo Time Correction

Prana incorporates Goldmund's proprietary Leonardo time-correction technology.

A loudspeaker's drivers and crossover can introduce phase shifts that cause different frequencies to arrive at the listening position at slightly different times. Goldmund developed Leonardo to digitally realign those frequencies in the time domain. Goldmund

The objective is greater coherence across the frequency spectrum, more precise localization of instruments and voices, improved soundstage depth and tighter transient behavior.

This is an important distinction between Goldmund's approach and conventional DSP used simply for EQ. Leonardo addresses time and phase behavior, not just frequency-response amplitude.

Proteus LS Loudspeaker Modeling

Before Prana's physical architecture was finalized, Goldmund modeled the loudspeaker using its proprietary Proteus LS mathematical system.

Proteus LS evaluates parameters including:

• Enclosure shape and volume
• Driver characteristics
• Driver position
• Membrane displacement
• Impedance
• Volume velocity
• Edge diffraction
• Sound pressure
• Amplitude
• Phase
• Group delay Goldmund

The modeling is then used to calculate the DSP configuration, including crossover behavior and Leonardo time correction.

This gives Prana an unusually integrated design philosophy: cabinet, drivers, amplification and digital processing are engineered as one complete acoustic system.

35Hz–25kHz Frequency Response

Goldmund specifies the Prana's frequency response at:

35Hz–25kHz (-6dB). Goldmund

Low-frequency loading is handled through a vented enclosure working with the dedicated 9-inch woofer and its 250-watt Telos amplifier.

The 7-inch driver handles the critical midrange region, while the soft-dome tweeter reproduces high frequencies through the system's upper 25kHz specification.

Wired Digital & Wireless Playback

Despite its substantial physical presence, Prana can form an exceptionally minimalist reference system.

Each speaker provides:

1 × digital S/PDIF input
1 × wireless audio input. Goldmund

A computer music library can therefore serve as a wireless source for a standalone Prana system.

For systems involving multiple sources—such as a high-end streamer, television, disc transport or other digital components—Prana can be combined with Goldmund Hubs and processors to provide source selection and broader system control. Goldmund

This gives the system two very different personalities: it can operate as an extremely clean active digital system or become part of a much larger Goldmund reference installation.

Goldmund Mechanical Grounding

The physical construction of Prana is engineered around Goldmund's Mechanical Grounding principles.

A specialized mechanical path running through the loudspeaker structure is designed to evacuate unwanted vibrational energy through the speaker and into the supporting surface. The substantial mass of the enclosure further helps control parasitic vibration. Goldmund

Goldmund introduced its Mechanical Grounding technology in 1982 with the goal of reducing structural resonance that could otherwise introduce coloration into the reproduced signal. Goldmund

For Prana, the mechanical structure is therefore functional as well as visual.

Apologue-Inspired Architecture

Prana belongs to the design lineage established by Goldmund's iconic Apologue loudspeaker.

Its architecture uses two stacked aluminum enclosures positioned inside a metallic supporting frame, with distinctive circular elements securing the cabinets within the structure. Goldmund

The substantial aluminum enclosures are micro-blasted to produce Goldmund's characteristic matte finish.

The design allows Prana to function as both a reference loudspeaker and a major architectural element within a listening environment rather than attempting to disappear visually.

176-Pound Aluminum Construction

Each Prana measures approximately:

18.90 W × 38.98 H × 18.74 D inches
48 W × 99 H × 47.6 D cm

and weighs:

80 kg / approximately 176 lb per speaker. Goldmund

A stereo pair therefore weighs approximately 352 pounds before packaging.

Goldmund supplies the pair in a dedicated protective flight case measuring 105 × 117 × 59 cm, with the complete packaged system weighing approximately 206 kg / 454 lb. Goldmund

That's useful information to retain on The Grid listing because this is clearly a product where delivery and installation planning matter.

Finish Options

Goldmund's current Rev. B specification sheet identifies:

Matte Grey enclosure with Black grids
Matte Black enclosure with Black grids. Goldmund

The current Prana product page additionally states that anthracite grey is available upon request. Goldmund

For Shopify, I would make Grey and Black the primary variants and mention Anthracite Grey as an available-by-request finish rather than presenting it as standard inventory.

Why Active Goldmund Is Different

The significance of Prana isn't simply that Goldmund put amplifiers inside a pair of loudspeakers.

The architecture eliminates several variables normally present in a reference system. Goldmund controls the drivers, amplification, digital crossover, gain structure, delay, phase correction and mechanical behavior rather than requiring separate components to work together after the fact.

Each driver receives its own dedicated Telos amplifier channel. DSP replaces the conventional passive crossover. Proteus LS determines the acoustic model. Leonardo corrects phase behavior. Mechanical Grounding addresses structural vibration. Goldmund

That integration is the real engineering argument for Prana.
