Trying to set up my apartment for music. Help!

[Wamsankas]

I have my iPad 2 so I already have access to my computer music with AirPlay... Does anyone have suggestion of a 4 speaker set that will wirelessly hook up my apartment for music. It's about 1,000 sq ft and its fine for the iPad to be hooked up to one speaker or receiver I just want the rest of the apartment to be bumpin. Thanks
