Hi\nIn the process of building my theater and can't decide whether to go for 7 or 5. Looking for some input from folks that have had or heard both. I do not have the surrounds yet but the fronts are RBH T2's, the center is a T1 and the (4) Atmos units are SV-615's. The surrounds will be SV-61's. \nI was looking at making the columns deeper and putting the surrounds in there but have moved them for better aesthetics and made them more shallow to allow room to go up on the riser. I'm now wall mounting the surrounds and putting sconces on the columns. \nAs for the AVR I have not decided on it for sure but am leaning towards the AVR-x6500h since it will have all the amp channels I need for either choice. Hoping Amazon will put it back on sale soon. Any other suggestions are welcome and appreciated.\nThanks!
