Yes i did have them in another box, the wall seems 1-2db louder with windows down, and still louder with windows up, but i havent listened to the other box in about 2 months so dont really remember.
here is the old box, this did a 147.4 sealed on "Put me in the freezer" so about 38hz, cracked the window and went up to 148.5. I plan on playing a tone (~45hz) with the wall just to see what kind of numbers it will do, but i dont really care about that score because this is a daily wall, so under 40 is what i play anyways.
