Hey guys. Alot of you probably have talked to me over at CAF, but this place to keep on topic with technical threads much better. I have a question that probably is for the speaker builders around here. (Dan?) I've been magnetically modelling speaker motors and I'm not sure what the "standard" materials are for them. By materials, I mean what grade of steel for the T-yokes and top plates, and what grade of ceramic magnets. Some preset options are: M-19 Steel M-27 Steel M-36 Steel M-45 Steel 1006 Steel 1010 Steel 1018 Steel 1020 Steel 1117 Steel and Ceramic 5 Ceramic 8 What would be the best to get the most accurate results? Thanks a bunch! Gveto
