Located in the main entrance tunnel to the Konjic complex, 25kt acoustically simulates the detonation of a 25 kiloton nuclear device in the vicinity of the bunker using massive blast sounds and reverberations created from audio samples previously taken within the bunker (ventilation systems, tunnel ambience, gas burners and other sounds).
When played in the space the dynamic acoustics of the tunnel interact with the recorded sound, intensifying the sound and sending it some distance into the open air.
The bunker was designed to withstand a 25-kiloton impact and the installation acts as a symbolic end-point of Cold War nostalgia. It challenges the passive consumption of Cold War nostalgia by drawing out the hidden death wish inherent in Cold War culture, acting as a reminder of how close the Cold War sometimes came to a final apocalyptic confrontation.
Visitors are exposed to this high-volume sound on entering and leaving the tunnel and so far over 3000 people have experienced it.
