Thanks mucho for the info Martin! Ya ever want to get rid of some of the Lowthers contact me OK?, i would be interested in doing a direct comparasion to the 206e. The 206e (with a Qts of .18,96 db 1 watt/meter) may turn out better than we all think as i have been running them in my horns and am very satisfied.Gotta hand it to huge magnets(not near the PM Lowther series though) and light cones, just cant beat the definition and speed. ron
