Muralman1...This sounds the same as Maggies, except the magnets run in horizontal rows instead of vertical rows.
Sogood51...Having magnets only on one side (front or back)of the panel does theoretically give an asymmetrical drive, but, because the panel excursion is so small this effect is also small. Also, keeping excursion small by using a subwoofer minimizes the asymmetrical drive situation. This would logically improve midrange performance...more so than with a cone driver where assymetrical drive is not an issue.
As I understand it (correct me if I am wrong) the magnets of a ribbon are located IN THE PLANE of the ribbon, to the left and right. This only is possible if the ribbon is narrow.
