Just one error though.......
Meadowlark and Thiel ARE time and phase coherent speakers.
........
yeah, I know that Thiel does advertise that their speakers are phase coherent but I do not believe that to be true hence my statement the way it was written.
Here is some proof to back up why I do not think that Thiels are phase coherent:
http://www.stereophile.com/content/thiel-cs6-loudspeaker-measurementsThis is for a Thiel CS6 speaker. Look at Fig 1 which shows the impedance & phase plots. The phase is all over the place going from -45 deg at 45Hz to +22.5 deg at 20KHz & every phase angle in between. IMHO this is hardly phase coherent!
http://www.stereophile.com/content/thiel-cs24-loudspeaker-measurementsThis is for a more recent Thiel CS2.4 speaker with the review done in late 2005. Again, look at Fig 1 which shows the impedance & phase plots. It's worse the older CS6 speaker as there's even more phase shift in the 20Hz-20KHz audio band!! Once again, hardly phase coherent; au contraire, it's quite phase incoherent.
In comparison, look at the impedance & phase plots in Fig 1 of an older Green Mountain Audio speaker - the Diamante. This review was done in 1998. Look how flat the phase response is in the 200Hz - 20KHz range. Very nice indeed! Now, this sort of speaker is distorting the phase minimal hence far, far more phase coherent. There is a dip in the phase to -30deg at 70Hz due to the bass enclosure (the bottom rectangular box).
