Speaker terminals on AR-4X?


I just got an old pair of Acoustic Research AR-4X to play with. But the speaker terminals don't tell me which is positive or negative, there is just the number 1 and 2 above the terminal. Anyone know which is which?
Thanks

According to the AR card on the back of mine, I do not think it matters;
It says "Connect the 0 and 8 ohm terminals on the amplifier to the speaker inputs marked 1 & 2 ."
A good resource is www.classicspeakerpages.com
As long as you connect them both the same all you have to worry about is absolute phase, which varies by recording and equipment anyway.
Try a 9 nolt battery.When the positive is connected properly,the woofers will move outward.
