Speaker Ohm Question

[braintheory]

I got a vintage speaker yesterday that is missing the back cover that would list the ohm rating, but with my multimeter I got ~10.2 Ohms. Would it work ok to use these in a cab with my 8 ohm speakers that typically measure under 8 ohms actually? Or should I use them with my 16 ohm speakers that actually measure less than 16? What is ok to use them with? Thanks in advance!

I would consider it an 8 ohm speaker

Agreed
Every speaker Ive ever checked with a meter was slightly off its rating, and usually slightly over it

What would be considered too much of a mismatch though? Some of my “8 ohm” speakers measure in the 6’s and 5’s and some of my “16 ohm” speakers measure in the 12’s. The other question if I use “16 ohm” speakers measuring in the 12’s would I be better off using the 8 ohm input of the amp being used with them?

You will get a hundred different opinions on this unfortunately.

Generally speaking it’s safer to put a smaller ohm load into a larger ohm speaker, I.e better to hook an 8ohm amp into a 16ohm speaker than a 16ohm amp into an 8ohm speaker

Some people strict about mismatching loads, some are less worried about it. Neither side is necessarily correct 100% of the time

Impedance and resistance are not the same thing. Thats why testing a speaker with a dmm always reads off. Iwould call that a 16 ohm speaker. IME they always read lower.
