When I built my box for my 10, sundown suggested a box size of 1 cube after displacements. Yet when I came on here for box advice, people were recommending I run up to 1.25 cubes. Why is that? Is sundown recommendations the bare minimum? I'm just wondering because I'm in a transition stage to a new box and I'm wondering if I should keep the 1.29 @ 31hz box I have (which my E10v3 sounds absolutely amazing in) or if I should experiment with a smaller box built closer to sundowns specs. My main goal is to dig deep into the lows.
