[QUOTE="Art Welter, post: 202052, member: 52"] Drew, The square magnets allowed a straight shear to be used for the backplate, an easier to maintain tool than a large round punch, and less scrap to deal with. Less efficient magnetically, between the lower flux density and round wound coils the old CTS/early Eminence were about 3 dB less sensitive than EV or JBL speakers. They were more than 3 dB cheaper ;^). After clearing out the shop after 20 years in preparation for next week's move, scrapped over a ton of metals and obsolete speaker cabinets... Good luck with your sales! Art [/QUOTE]
