ASI Basic Copper Resonator

ASI Basic Copper Resonator

The 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.


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 absorption 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 acoustic resonators are small but powerful tools for room tuning, noise reduction and to minimize air turbulences. Our retailers and distributors in the hifi sector are trained in how to set up basic and more advanced resonator treatments. On the next page, we also provide starting instructions for standard rectangular rooms. 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. We encourage you to experiment. Please allow for the full effect to stabilize over 24 hours.



Copper and Silver are the main components of the basic resonator.

The base is made of finest soft instrument maple.

Sound character: Straight, fast.

Location to install: Install it on wall behind the speakers at the mid point and don't exceed 15cm in height when measured from the floor.
