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

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.
