How do the Magnepan 3.6r compare to the new 1.7

Elizabeth, It could be the reviewers who claim to hear this discontinuity are too close to the speakers. With large speakers it is important to create some distance to get a proper blend of the drivers. Big speakers are made for big rooms. They are not near field speakers. This is also true of speakers like Dunlavy SC-IV where drivers have a 6' span across the front baffle.

Macdadtexas, Some people are more sensitive to a speaker's coherency than others.
