Resonance Free Aluminium (RFA) Enclosure

The Save:

Sometimes called “the save” by our customers, the Burson RFA enclosure is constructed from precision machined aluminum panels.  Only 8 stainless steel bolts were required to join the enclosure, which then became virtually indestructible.

Resonance Free:

Resonance produced by nearby speakers, vibrating components and transformers can all pollute audio signals.  We took great care during the design process to ensure the thickness of each wall varied from each other to increase the mechanical damping factor. The RFA enclosure displayed superior mechanical noise rejection (internal and external) compared to the conventionally folded steal enclosure used by most audio manufacturers.

Optimizing the Idle Current:   

The geometry of the case and the precision of the enclosure allow the entire case to disperse heat evenly, and act as a giant heat sink. A steel folded or thinly built aluminum case could never achieve this. The AF enclosure removes the need for those ugly heat sink fins and allows our machines to be set to a high idle current, which results in lower distortion, higher output and better overall dynamics.
