White dot on terminals. Is this the positive or negative...?

[atilsley]

Have old pair of comp drivers...Mlynar (or similar name).

There's no positive or negative marking on the terminals, except a white dot.

Is this positive or negative?

Thanks.

I'd guess negative if I had to. Technically you should be able to go both ways with it and just put it to the one that sounds the best.

Remember that with amplifier output you are dealing with an AC (alternating current).. there is really no positive or negative. That white dot could more than likely be used as a reference.. as long as both channels are hooked up the same and the speakers are in phase you will be fine..

Use a AA or other small battery. If connecting the white dot to the + on the battery while connecting the - to the other terminal creates a forward cone movement, the white dot is the +

Not with HF compression drivers. This test should only be performed on woofers.

The driver is Emilar EA 175, Alnico....any good?

This article seems to suggest so.
