Acoustic System Franck Tchang’s Resonators


Delivery time: call us



Franck Tchang’s acoustic resonators are available in two versions and five models each. The home-based models use tall Maple wood bases and a loose tripod mounting for the bowls. The equivalent Pro models use Brazilian Rosewood cubes and captive mounts as shown in the last inset. The five different models are based on pure metals and proprietary alloys and simply called Copper, Silver, Gold (yellow gold), Gold Special (Red Gold) and Platinum.

Please call us if you’re interested in the Pro version. The home based models are generally in stock.


The concept and technology break down into four areas:

• Use of high-density precious metals rather than big masses of foam or fiber glass panels to preserve space.
• No absortion of sound but conversion of the room’s low frequencies into high frequencies to cancel unwanted resonances.
• A tool to fine-tune a room’s harmonic response like the finest of musical instruments through the properties of precious metals.
• Lifetime performance without any potential for degradation and easy adaptation from one room to the next.

The resonators are powerful tools for room tuning, noise reduction and to minimize air turbulences. Very small adjustments in how high or low the resonators are mounted and how their wings are turned relative to the listener can have surprisingly powerful effects on soundstage focus, virtual stage width and depth, bass clarity, treble extension and more. Please allow for the full effect to stabilize over 24 hours.
