Item #: 4258
Object Class: Safe
Special Containment Procedures: SCP-4258 is to be stored in a soundproof storage unit in Site-129. Access to this unit is restricted to official testing. Testing of SCP-4258 is strictly prohibited until further notice.
All instances of SCP-4258-C are to be kept in seperate soundproof humanoid containment chambers in Site-46, and are to be allowed contact with each other for testing purposes only. SCP-4258-C instances must be hand-fed liquidated meals 3 times a day, and Foundation officials are to engage instances of SCP-4258-C in Re-Education Protocol-J.

Description: SCP-4258 is a pair of M-Audio BX-5 speakers measured at 251 x 175 x 196mm, and weighing 5 kg. Both speakers are connected to each other by an auxiliary cable in the rear but are not connected to any power source, and do not have any observable internal power source. Despite having no apparent power source, SCP-4258 consistently produces a static tone at 41 dB.
Upon perceiving the tone produced by SCP-4258, a subject will perceive themself as being in the drivers seat of a vehicle, which is typically described as being identical to a vehicle that the the subject owns or has driven before. The vehicle (hereby identified as SCP-4258-A) has all windows covered in a black matte material excluding the front windscreen. The front windscreen shows the subject the view from there own perspective outside of SCP-4258-A.
When a subject perceives entry into SCP-4258-A, all nonessential motor functions of the body cease, and the subject can only have their body function as they wish by interacting with the systems of SCP-4258-A. If a subject who is experiencing SCP-4258-A attempts to exit the vehicle their body will immediately cease all functions, causing total brain death unless immediate medical support is applied. Subjects who have left SCP-4258-A and survived consistently report having entered a location (hereby identified as SCP-4258-Prime). As all accounts of SCP-4258-Prime are purely colloquial, refer to Experiment Log-1 for more details.

Discovery Log: SCP-4258 was recovered on 20██/4/23 in ██████, Adelaide, Australia. SCP-4258 was brought to the Foundation's attention after a Foundation member working undercover in ASIO was brought in to investigate anomalous events in a share home in ██████, which had led to the deaths of 3 students and 2 Police officers.
After recovering SCP-4258 from the home, the landlord and surviving occupants were administered class-B amnestics, and a false report of a gas leak was established. The owner of the room in which SCP-4258 was found, Bradley Tarnell (hereby identified as POI-1) was reported missing by family and friends, and could not be located by Foundation efforts at the time of recovery.
