Sandy,
How many channels of output do you have? assume 2 jacks=2channels
How much do you want to spend? M-audio or Behringer speakers with amps included are good coices for a home.
How much weight can you carry comfortably? This determines the size and weight of the speakers for you.
So 2 M-audio BX8a speakers and a subwoofer should do nicely. Around $1000.00 more or less.
