Thank you for the reply.
I have the early square tweeters. MB Quart 95 6383 8 Ohm with double round magnets. I found one (both were cooked from hookup by prior owner without crossovers) and am still running one NOS 4 Ohm I bought from MB Quart's successor with a series resistor until I land another, or, better yet, get the part number for the later round MB Quarts and chase down a set.
