We're hoping to get some time down there this weekend....
The screen size isn't as bad as I thought it would be, a bit of a shock to the system, but not bad. I'm already happy with it. I did move it up to 22 inches off the floor, my big toe was on screen while reclined with legs crossed.
I do want to increase it to 115" just to compare, I'd say the 90" is perfect from my chair for games though. Just want to see 115" from the back row.
It sounds great, I needed to lower the volume on the receiver again.
I ended up with more room between the rows, not sure how that happened...
As it is now the main seats (ears) are 8' from the back wall while reclined.
The Martian tonight, fingers crossed.
