easiest way to go is powered speakers, jbl eons or Mackie SRMs. You may not think you need a subwoofer, but it can help it sound good and you'll find you can actually keep the volume lower and have a more full sound. 2400 sq feet is pretty big though, and while ambitious you may want to think about 4 speakers. 4 smaller speakers spread out will cover better then 2 larger speakers blaring from the front. But most likely you'd be fine with just 2 JBLs, these are pretty standard:
you don't need to worry about amps and all that stuff.
