Multiple woofers in a column have a time delay.Assume 3 woofers spaced 12" apart at 1, 2 & 3 feet from floor, a 15 foot listening distance and a 4 foot ear height. Relative to the direct wave from w1, @ 350Hz w2 ≈11° and w3 ≈30° of phase shift.
From the floor, w1 ≈177°, w2 ≈106° and w3 ≈47° phase shift for the 45° wave from the woofer.
Please explain how the laws of physics have been defeated by speaker stands.When a speaker is on a stand, it is closer to a point source than is a large box.
