Would love the feedback on this setup before purchasing.

After scouring facebook marketplace and ebay ive landed on this setup and would love your thoughts on it and if I should spend my money elsewhere.

For the reciever I chose the denon avr x1500h for $150. I chose it because I need HDCP 2.2 and 4k passthrough and can support my 7.1 setup.
For the speakers im looking at getting a polk tl1600 sub and 6 tl1 satelites with a tl1 center channel for around $160 as well. This will get me to a 7.1 setup which is what I wanted from the start.
