KLH Model Six terminals -- which is positive?

Hi folks -- newbie here. Background: Wife has two KLH Model Six speakers that she bought new in about 1971-72 (age reveal!) -- she still has the orginal Sherwood receiver she bought at the same time that I just had fixed. Again. They are incredibly good-sounding speakers. (And they weigh a ton -- the older I get the more they weigh.)

OK, to my question. I've seen posts here talking about three terminals and a bridge between B & C, but ours has only two -- left and right, plus the high-frequency switch. The terminals are unlabeled with nothing to distinguish them except their position, one on the left and one on the right, there's no plus or minus, no color, no L or R. I've just recently learned -- from the KLH manual (four pages printed on card stock) and elsewhere -- that you have to be sure the speaker wires are attached to the speakers the same way they are to the amp, and I can see I got things all kapakahi (messed up) and I have to do some switching around on amp and speakers. My cables are 14 gauge, blue & gray with banana plugs at the amp end, bare wire at the speaker. So if blue is positive attached to the positive/red socket, it should attach to the positive terminal on the speaker, right? But there's no indication which of the two terminals is which. I would guess left is positive and right is negative. Yes? No? I have scoured the web looking for an answer, and all everybody talks about is color coding/labeling and three terminals.

So that's my question: which terminal is positive? I'll go out on a limb here and bet the other one is negative.;-)

Thanks in advance. And if anybody can advise me on how to install banana plugs on these speakers -- what to buy, how hard it is, whether it's even advisable -- I'd appreciate that too.

You can find nice little screw terminal to banana adapters on Amazon but you have to buy 10 ... The real way to determine polarity on your speakers is to use a 1.5 Volt battery and a piece of wire. Just hold the negative end of the battery to one of the speaker terminals and somehow hold the wire to both the positive end of the battery and the other speaker terminal. If the woofer moves OUT, the positive speaker terminal is the one that you've attached to the positive battery terminal to. If it moves IN (back into the cabinet), it's the opposite. Clear?
