OT: Home theater

Hi, so since I find the forum very nice here and I’m sure there are some home cinema friends around, I put my question in here. Since I don’t need a car anymore at the moment, my system has been dissolved (student became) and moved together with my wife, I wanted to put together a home cinema system for “small” (for you maybe small for me already big) for about 500-600€. AV receiver will probably be a Pioneer 516 or depending on a 416, I’m open to suggestions. I might be needed to buy. As far as I’m not sure, the speakers are. For the time being, a 3.1 or 2.1 system would be enough. I’m only going to watch movies and put value on good bass, which you already feel good with low levels (my Xion 15BR spoiled me) What could she recommend? As a sub maybe a Mivoc SW1500A?
