ATC use phase correction in their active speakers. The overall result approaches linear phase with smooth phase behaviour across the crossover. No speaker will be perfectly linear phase as mechanical drivers aren’t linear phase.
That said, minimum phase filters and MQA are best avoided as they introduce significant phase distortion by delaying the arrival of high frequencies vs low frequencies. The characteristic effect of MQA is most noticeable on the plucking of guitar strings which sound disconcertingly unnatural - the transient of the string being plucked seems to start at a lower pitch than is natural. Minimum phase filters and MQA muck up natural timbre - hardly surprising given the way they shift phase around.
