Here's the situation... Going to a party. The room has power, but the house does not have internet (believe it or not...), and the area doesn't really get strong cell/data signals. Are there any speakers that I can simply plug into a power outlet (or use batteries) and then can talk to my iPhone (or MacBook) wirelessly/bluetooth, and the sound can fill a room maybe 45ft x 60ft (doesn't have to be super loud like a concert, more like background music). I would like there to be 2 (or more) speakers in the room so everyone can hear clearly. Portable speakers with an iPhone dock (like a Base SoundDock or or Logitech S715) I don't think will cut it - I don't want to have to have it cranked up by some people just to folks on the other side of the room can hear ok. Fine if I have to get something to plug into the iPhone/laptop, or some main "controller" unit that I have to plug into them that then talks to the speakers. Basically I'm envisioning something like a Sonos S5 that doesn't require an internet connection (which it seems to from all the material I have read). I'm flexible on dollars - just can't have any cords running across the room. Or like a Jawbone JAMBOX, but have the ability to set up 2+ speakers at the same time (doesn't have to be stereo, which I'm not sure would even be possible anyways). Thanks so much everyone!!
