This is a used 12" woofer from a Pioneer model CS-R590 speaker.   Being used, it may have minor marks and need a light cleaning.   I have 2 of these available at the time of the listing.   Each buy it now is for 1 woofer.  One woofer measured 7.5 ohms, the other 7.4 ohms.  Last picture shows the label on the speakers that shows the model number and is not included.   Just used to show what model these came from.
