familiar with 70s Infinity?

ive been working on a refoam project on a pair of infinity RSa speakers i bought them in really nice condition.
solid oak cabinet.
emit tweeter.
Great deal for $19.95. thing was they needed a refoam. so i ordered a set, guess what they sent me the wrong size. had to spend an extra 15 dollars plus shipping all over again. what could i do. i wanted them fixed.
and im finally just finishing up thesecond one. still using the original dust cap. so far no coil rub on the first one. second one just needs to have the dustcap glued on.
didnt want to sacrifice them for that black colored dust cap from speaker foam. wasnt sure at first if i would be able to use the original again. as the direction paper said to cut off the original dust cap. but they sent me a unmatched cap. the woofers are grey. not exactly sure what its made of. but it seems lite. and stiff. i saw a listing for this same speak in sf craigs list with stands include for 199 dollars. ill probably stack em on my subs.
so!
anyone hear these speaks back in the day. what was it about them that gave you the conclusions about them. nope they dont have the emit-r tweeter. just the emit. and no dedicated midrange driver. both tweets seemed to work. didnt really play them just tested them. didnt think playing them with tore up surrounds will not do them justice. so i held back on using them.

edited the (now coil rub) to no coil rub. both with no coil rub. finished and dried.
