This is the 2 story 15 X 20 room opened on 2 sides. {{SNIPPED}} The speakers definitely benefit from a sub woofer. As most of you know I hopping to go to strictly a stereo set up no sub. Many advised to get the 80’s for that, which is still a possibility.
Oz:
If I'm understanding the situation correctly, I don't think going to the 80s would make much difference. They only go a bit deeper and a little louder. I think a room with as much cubic feet of volume as you have would not be filled with
any full-range floorstander, and a sub will be necessary. It's simple physics of trying to move enough air for satisfying bass in an area with many cubic feet of air vs. a smaller amount of cubic feet in a more typical room.
Great review though!
