5 ohms speakers

I picked up a pair of pre-historic german speakers at a garage sale,
and they have 5 ohms written on the back.
How do I hook them up to a 1980 receiver?

Tomi Holger Engdahl...

If that receiver can handle speaker impedances down to 4 ohms
(usually listed on that era 4-8 ohms speakers),
then just attach them to the amplifier speaker outputs.

Laurence Payne...

Attach them to the speaker outputs. :-)

Also, the wires have some strange plug at the end, one blade is larger
than the other one. How does that relate to the normal red/white
scenario?

Tomi Holger Engdahl...

If you have that DIN speaker connector like this
Then the pinout is this:

The larger blade is minus side (white on your red/white color code).
And the smaller blade is plus side (red on your red/white system).

Laurence Payne...

Possibly a DIN speaker plug. Take it off and substitute whatever your
amplifier needs. Maybe bare wire. As long as larger blade goes to
the same side of each amp. output, it doesn't matter which. In the
unlikely event of your ears shouting "Hey! The absolute phase is
WRONG!" try the other way. But they won't :-)

Gert Wiersema...

Whahaha! :)

punkinaro...

ahahahah ( that`s me pretending to understand)

what`s the absolute phase?

Walt...

A positive voltage on the red amplifier output should make the speaker
move forward. A negative voltage should make the speaker move
backwards. If this is what's going on, the absolute phase (polarity) is
correct. If a positive voltage makes the speaker move backwards, the
absolute phase is reversed.

You probably won't be able to hear the difference as long as both
speakers are wired the same way. But if one moves forward while the
other moves backward, the stereo image will sound weird and indistinct.

Jeez, I`m picking up lots of old audio stuff and I don`t even know the
basics. And still, I`m bringing home stuff every week, it`s like a
disease.
