Bare with me please, I am brand-spankin' new to Mac! I just got a Mac Mini. Love it. Now I'd like to wire the whole room for sound. I use Spotify religiously, and watch dvd's on my computer. I'd like speakers in front, speakers in back, and a subwoofer. It would be ideal if the rear speakers are wireless. I'm having NO luck on any searches or sites. I see recommendations in these forums but a lot of it is Greek to me, ie, Airport, Airplay, whoza-whatsa... I'd like to spend as little as possible, no more than $200. It is a small room, by the way. Please help with suggestions, and walk me through it?
