Six, fifteen-inch cardioid subwoofers are paired and hung in space as three static objects; each composed of one subwoofer facing upward and another inverted downward, creating between them a pressurized void where phase cancellation imposes a counter-intuitive quiet at proximity. Moving further, however, the six discrete channels of low-frequency audio create an evolving field of invisible friction that interacts with both the physical architecture of the exhibition space and the viewer within it. This work is one of several recent attempts by Frost to reclaim the materiality and by-design invisibility of the very live sound equipment upon which he has built his career as a performing artist, directly challenging and exploiting its unique properties as an innate sculptural and visual medium.
