Hi everyone, I am new to the HT forum. I am in the process of doing my basement over and looking for a HT surround sound. The media room is about 24'W x 12'D with the ceiling at 6'-10". I will be purchasing the Sharp 80" and would like to get a decent surround sound system to compliment the TV. Primary use will be cable content. Also will be hooking up an Xbox, Apple TV and PC. I do not have a Blu-ray player however In the future I may think about one. My initial surround sound system is as follows: -Onky TX-NR609, 7.1 -Polk TL250 5-pack (front, center, rear) -Polk TL250 satellite (sides) I still need to think about a Sub. Any recommendations? I’m not looking to spend a fortune on a sub however something that will compliment the system. Also, any comments on my initial HT thoughts?
