Hello,
I have a few speakers, i want to use them but the resistance is 20 ohm! They are really quiet. I got transformers with them, but they have 3 wires and i dont know how to connect them. If somebody can tell me more about this transformers and connection i will be thankful.
P. S.
Sorry for my bad english (i come from non-eng speaking region) :)

Sounds like they are for commercial use. To be used on a 70 volt system for background music in an office or department store setting.

Yep, they sound like commercial 70V style speakers.
Try this. Unsolder and remove the wires between the output of the transformer and the terminals on the speaker where the tinsel leads attach. Now with a meter you can see how much resistance the speakers voice coil has all by itself and then determine whether it will work out for your needs. With the transformer attached to the voice coil it may throw off the true reading of the speakers voice coil.
