Hi,
I'm scratching my head over this one!
In measuring my speakers in my media room to ensure the crossovers are wired and performing correctly, I am getting phase reversals in the tweeter region (2.2K Hz+). The microphone is at the listening position, ~ 10 feet from the speakers. I'm measuring them one at a time, then calculating and presenting minimum phase. Sometimes the phase reversal happens at ~2kHz, 7 kHz, etc. I am repeating measurements without any changes to setup - I get perfect results, then? Using a MacBook laptop running REW and a Umik 1 mike plugged into the USB port on my laptop. Two examples here of the same speaker, one measurement made right after the other...
Any help greatly appreciated!!
Many Thanks
Tim
