This is a used Klipsch Promedia woofer.   Being used, they may have minor marks from use and could use a light cleaning.   I have 3 of these available at the time of the listing.  Each buy it now is for 1 woofer.   Woofers measure between  5.0 and 5.1 ohms.  Last picture shows the speaker similar to what these came from and not included.
