Reply to Don't know what kind of speakers to get??

I was planning on getting a behinger 15" 1000w powered speaker since I'm kinda in a budget. But then I was looking at some like thism. bestbuy.com/m/e/product/detail.jsp?skuId=9784287&pid=1218173777200. I honestly don't even know what I need to set up a passive sound system. Any help will be thankful. I want something I can practice at home with but I can take to maybe some small house parties and they sound good. Looking to spend maybe 200 or 300 at the most
