speaker ohm question

[death by chandelier]

I've got a couple of old CTS 10" speakers (137-7607) and I'm trying to figure out the ohms of the speakers.

On the back of the speaker magnet there is stamped 8.16 OHMS.

Is this 8 (point) 16 OHMS or 8 (to) 16 OHMS? Or neither one?

I'm assuming if 8.16 means its an 8 OHM speaker that if I wire them in series it will be a 16 OHM cabinet or parallel it will be 4 OHMS.

Sorry if this is a dumb question.

I would just put a digital multitester on it set to ohms and see what it reads. I have never seen a speaker classified with anything other than a whole number for its impedance rating, since it's a nominal number anyway.

Hey Randy. Thanks for the reply.

I checked a speaker out with the multimeter (analog). I got a reading of 11 ohms.

I read somewhere to get the nomimal number you multiply by 1.3. That gives me 15.6 which would seem to make the speaker 16 ohms.

I was thinking with 8.16 OHMS printed on the speaker it would be a 8 ohm.

I wired up the speakers in parallel and got a reading of 6 ohms --> x 1.3 = 7.8 or 8 ohms.

16 ohms seems to be the answer.

The "8.16 OHMS" is still kind of odd.

Thanks again.
