Hi, I realize this is waaay below the level of sophistication of systems you normally discuss here, but I'm hoping the experts on this forum can help me out. I just got a new TV (Vizio M65-E0) that has only one HDMI port capable of handling 4K UHD input. I have two devices currently that output 4K UHD (Blu Ray player and Roku) and it's possible that I'll be adding more in the future. Because of my room setup (and my wife's wishes) I can't do rear speakers. So what I'm looking for are recommendations for what subwoofer to get, and what speakers to get for the left, right and center channels for below $500 total. That's not a hard upper limit on the cost, though. I'm also looking for recommendations a receiver that can handle 4-5 4K UHD inputs, and give me good sound the best possible sound with just the three front speakers. I'd like to be able to adjust the volume on the center speaker separately to make voices easier to hear in movies. I've posted a separate request for receiver recommendations at https://www.hometheaterforum.com/community/threads/receiver-for-3-1-speaker-setup.355236/ Thanks in advance!
