This is a used Eminence 12" woofer. I have 2 of these available at the time of the listing. Each buy it now is for a single woofer. One measured 5.7 ohms, the other 6.0 ohms. Being used, they do have some minor marks from use and could use a little cleaning. Printed on the back is 12800 67-8549. If you choose the UPS shipping calculator, it may be shipped FedEx ground.
