I am looking for a new speaker system that is in the ball park of $300. I am looking for something that I can hook my phone up to via bluetooth and that will fill a room with sound. I will also be using this for movies so sound sound if preferred. If at all possible, I would like the system to be portable, or possibly be able to take a single speaker to use elsewhere. I am considering the Polk Audio MagniFi Mini. This would be for basically all audio needs in my dorm room. Any opinions and comments are greatly appreciated! Thanks
