As Yogi says, when you come to a fork in the road, take it.
You're at that fork right now.
While they appear similar at first glance, home speakers are different creatures from those used for PA work, which is what you're asking about.
What do you want? Nice smooth home speakers or PA speakers optimized for maximum sound and coverage with the minimum power?
Also, how many speakers are you expecting to buy?
Does that dollar figure include a subwoofer?
If you're not too picky on sound, get hold of some big Cerwin Vega! speakers. They will play loud for those social functions.
