One way could/should/would simply, which way does it "sound more realistic"?Like - if you shut your eyes are you more "at the concert" or "less at the concert"?
And don't expect it to be a quick learning thing - it took me ages to be able to confidently choose - and if you find you are thinking too much, just ask a woman - mine has it 100% in seconds, everytime!
Phase coherent means the leading edge of a pulse/transient waveform has the same direction pressure from the speaker system at all frequencies.
Many multicone speakers have their midrange wired out of phase with the bass and tweeter - so a single unidirectional pulse does not come out as a pulse at all - but a mixture of positive and negative pressures.
Single cone speakers (Lowther etc), full range electrostats (ML CLS etc), most panels (Apogee & Magnaplaner etc) and some carefully designed multiway cone speakers (Theil etc) are phase coherent, most others are not - especially if the designer's main focus was achieving extreme flatness of frequency response.
OK?
