Hello!
Tell me why this happens.
If you shoot the frequency response separately through the channels, exactly on top.
But if you shoot the frequency response of two channels at once, a wide dip at medium frequencies.

Comb filtering, essentially. A small difference in the distance from the mic to each speaker means there are phase differences between them that cause constructive and destructive interference when they sum at the mic.

Гребенчатая фильтрация, по сути. Небольшая разница в расстоянии от микрофона до каждого динамика означает, что между ними существуют разности фаз, которые вызывают конструктивные и разрушительные помехи, когда они суммируются в микрофоне.
