Two Jensen P15R speakers.

One from 34th week of 1956

One from the 8th week of 1957

Both are in GREAT shape! Original cones sound awesome.

8 ohms each.

Of note, all vintage Jensens are wired backwards, the positive is negative and the negative is positive.

Early JBL speakers are the same way.

To confirm this, put the positive of a 9v battery on the positive of the speaker, and negative of the battery to the negative of the speaker, you’ll see the cone pumps backwards.

Put negative of battery to positive of speaker, and positive of battery to negative of speaker, a need you’ll notice it pumps forward.

Care should be taken when wiring the speakers to be sure they are both in phase and both pumping forward.
