Goldmund Rhea Active Stereo Speakers

The Goldmund Rhea Active Stereo Speakers combine reference-grade loudspeaker engineering, 650 watts of built-in Telos amplification per speaker, 24-bit/96kHz DSP, Proteus LS modeling and Leonardo Time Correction in a fully integrated 3-way floorstanding system. Each Rhea uses a 12-inch woofer, 7-inch midrange and soft-dome tweeter, delivering frequency response from 26.5Hz (-6dB) to 25kHz. Goldmund| The Art of Sound

Designed for listeners who want true high-end performance without separate power amplifiers, external crossovers and conventional speaker cables, Rhea accepts both wired digital S/PDIF and wireless audio. Its active architecture allows Goldmund to engineer the drivers, amplification, crossover, timing and mechanical structure as one complete system.

650W Telos Amplification Per Speaker

Every Rhea contains three dedicated Goldmund Telos amplifier channels:

• 175W for the soft-dome tweeter
• 175W for the 7-inch midrange
• 300W for the 12-inch woofer

That's 650 watts per speaker and 1,300 watts across a stereo pair. Because each amplifier directly serves its assigned driver, Rhea eliminates the conventional passive crossover between the power amplifier and transducer. Goldmund| The Art of Sound

3-Way Active Loudspeaker

Rhea's driver complement consists of a soft-dome tweeter, 7-inch dedicated midrange and 12-inch woofer in a vented enclosure. The large woofer and dedicated 300-watt amplifier provide substantial low-frequency authority, while the separate midrange and tweeter reproduce the upper spectrum without requiring the woofer to cover an excessively broad frequency range.

Goldmund specifies frequency response at 26.5Hz (-6dB) to 25kHz, giving Rhea genuine full-range capability for reference two-channel listening. Goldmund| The Art of Sound

Proteus LS & Leonardo Time Correction

Goldmund develops Rhea using its proprietary Proteus LS loudspeaker-modeling technology, which calculates the acoustic and mechanical behavior of the complete speaker system.

Rhea also incorporates Leonardo Time Correction through its internal DSP. Rather than addressing frequency response alone, Leonardo is designed to correct time-domain and phase behavior introduced by the loudspeaker system and crossover. Goldmund| The Art of Sound

Together with the active Telos amplification, these technologies allow Goldmund to control the loudspeaker as an integrated system rather than leaving amplifier, crossover and driver interaction to independently selected components.

24-Bit/96kHz DSP

Rhea's internal digital processing operates at 24-bit/96kHz, managing crossover filtering and the proprietary Goldmund correction technologies before the signal reaches the individual Telos amplifier channels. Goldmund| The Art of Sound

This architecture is fundamental to Rhea's design: DSP, amplification and loudspeaker parameters are engineered together rather than added as separate components.

Wired & Wireless Digital Audio

Rhea provides:

1 × Digital S/PDIF input
1 × Wireless audio input

This allows Rhea to operate as either a wired or wireless reference system. Goldmund| The Art of Sound

For example, Goldmund has demonstrated Rhea with the Eidos Streamer using direct S/PDIF connections, creating an exceptionally streamlined reference system with the source feeding the active speakers directly. Goldmund| The Art of Sound

Goldmund Mechanical Grounding

The Rhea enclosure incorporates Goldmund Mechanical Grounding, engineered to evacuate unwanted mechanical vibration from the structure rather than allowing resonant energy to remain stored in the cabinet. Goldmund| The Art of Sound

The substantial aluminum construction combines micro-blasted vertical and edge panels with brushed horizontal surfaces, creating both structural rigidity and the architectural appearance of Goldmund's current active loudspeaker family.

Reference Performance Without Separate Power Amplifiers

Rhea eliminates several components normally required in a reference passive loudspeaker system. The power amplification, active crossover processing, DSP and time correction are already integrated into each speaker.

That makes it possible to build an extremely high-performance system around a premium digital source without adding separate stereo or monoblock amplifiers and long runs of speaker cable.

For customers who prefer external amplification and a traditional analog signal path, Goldmund also offers the separately engineered Rhea Passive.
