My speakers are wired correctly, why does MultEQxt give a Phase error?
MultEQxt detects absolute phase for each loudspeaker. Some loudspeakers are designed with intentional phase reversals in the drivers in order to address crossover problems. MultEQxt will detect that and report an error. The best course of action is to simply check the wiring and press Skip if it is correct. MultEQxt simply reports a possible wiring reversal, it does not automatically switch the phase.
