In Reply to: I should have thought that time / phase coherent speakers posted by Timbo in Oz on September 27, 2016 at 04:06:51:
Time or phase coherency is not what were talking about, however, as important as that is. Were also not referring to the phase shift that speaker crossovers mightier might not produce. Abosoute polarity is either correct or it's not. If it's not it's reversed polarity and is 180 degrees from correct polarity. Thus, your speakers can be time and phase coherent but the system can still be out of absolute polarity. An component can be inverted polarity for example.Another way to look at it is if your system is measured to be in correct polarity using a test CD or record and the source CD or LP is reverse polarity you can correct for that by reversing the + and - at the amp output for both channels or at the speaker.
