Hey everyone I'm new to home theater systems and I was considering buying speakers and a sub from polk. I don't know how to tell if speakers will work/soon good with each other. I'm looking for a system that will last me at least 5-10 years. My room isn't that big(around 120 square ft) but I plan to use these in a larger room in the future. I already have the PSW110 sub picked out, could you help me with the rest? I was considering the TSI100s for either my front or surround speakers. Thanks!
