Is Bluetooth open to public?

[Bdaly]

Was sitting in the living room and the phantoms started to play music ( very loud) without me turning anything on and nobody else was home. I had to turn the power off to the speakers for it to stop. I live in a apartment building so I was wondering if someone access the phantoms Bluetooth or wifi? I have had the speakers for four months now and never had this problem. I have two silver phantoms and the dialog box and nothing else, tidal for music. How can I stop this from happening again? Thanks

This happened to me too.  It happened once. To make matters worse, it happened to me in the middle of the night around 2am.  I also live in an apartment building. I woke up from a dead sleep to find a loud newscast from National Public Radio.  At full blast, no less.  It was disorienting, to say the least.  After I was able to think, I pulled the plugs.  Later, I turned off the bluetooth to the two Phantoms (I have two Silver Phantoms).  I connected my Airport Express directly to the dialog with optical and ethernet.  The Phantoms are connected via WiFi.  Has not happened in the last month.  I thought the thing was possessed!  Ha! I guess they have been officially exorcised.

My dog freaked out then it happened, the speakers at full blast and me running around looking for my iPad and phone to lower the volume, only to realize it was Bluetooth and unplugging the power it's not easy to troubleshoot with the volume so loud. Found out how to turn off Bluetooth in spark.
