It has black metal cone, and dual 4 ohms.
Will try to make required pics.
As for refs. I am relatively new to car audio stuff, but already not that dumb (I think) in the area. I can give my
ebay user name to check. I had some selling/trading activity on other forums, not audio related, but do not know if it helps.
If the person who I will be trading with has good refs, I can ship first and wait the moment it arrives to recipient.
Here is the info from vendor site
