Vibration Cancellation

All loudspeaker cabinets, irrespective of their structure and weight, radiate energy at their resonant frequency. Extensive vibration studies carried out during Fenestria’s development phase gave the PMC design team the precise data they needed to tackle this issue in the evolving loudspeaker.

Adding a large weight (a so-called tuned mass damper) to the top of skyscrapers prevents the formation of destructive seismic vibrations during earthquakes. As the building oscillates, the mass moves in opposition, cancelling out the unwanted resonances.

Using the same principles, the planar wings of Fenestria’s cabinet have been precisely engineered to resonate in opposition to rest of the loudspeaker assembly, so that unwanted vibrations are eliminated before they ever leave the cabinet.
