    @OO1 I'm sure you saw this, he has one from '75 and one from '82. Same drivers in both, just the woofer might be different?

    the Driver combination for the 82 is different ,  the woofer is the 8 Ohms  ferrite K-22 -E  Tweeter is the EV T-35 ferrite square magnet ,


    However , the Midrange driver can vary in 1982 .    the pictures of the OP shows the K-52H Heppner

    The D  Network   is original  , although  it's  extremely rare  with these round capacitors    , you can see this by the metal holders of the capacitors   and no other holes in the wooden board to indicate that these were an Add-on 


    the Driver combination is the Alnico round magnet K-77/EV T-35   tweeter  , the K-55M Alnico  Midrange driver   -the Badge is the PWK Pie badge .


    the woofers  can be  -   2 types   A)- the orange  surround K-22 woofer  /EV SP-12B    or   B-  the Alnico K-22

    Please, quit while you are ten feet under. Was stainless used by the factory? Has anyone measured the stainless?


    Stainless is ferrous by the way, meaning it’s made with iron, but is has chromium to significantly reduce corrosion, and nickel, which in sufficient amounts will render the material “non-magnetic” I.e. it won’t be attracted to a typical magnet. 



     Lol ,  Stainless steel can be  magnetic or non-magnetic depending if the steel at it's core is  ferro-magnetic or not  .

    this screw question was repeated ad nauseam over the years     Mike Colter ,  who worked for klipsch Technical support  tested both the magnetic and non-magnetic  screws in the klipsch  anechoic chamber .

    I've tested the brass/steel screw theory in Klipsch's anechoic chamber. Acoustically (measureably) it doesn't make a gnat's butt difference what the screw is made of. Electrically, in theory, it might have some effect, but it's immeasurable on a frequency response curve, so it must not affect the values within the crossover network to any great degree.
