I am looking for a good speaker setup for my iphone 4. I would like the speaker to be wireless but i also own a airport express so i guess i can use that as well. I am looking for something quality in the 100-150 range. I am not to into the music audio scene which is why i am posting this. I am not sure what manf make good sound compared to others. I know bose but they are WAY too much. I just need a decent size single speaker i can put in a room when i have company at my house and have nice crisp music come out of. Thank you in advance.
