FS: Scanspeak Revelators 18S/8531
 
These are used and I removed the shielding and bucking magnet on them to make them less deep due to some mounting restrictions. They were used in my car, but DO NOT have any water/moisture damage. I have taken many pictures of them but if you need more detail please let me know and I can provide it.

Asking $275 shipped OBO to CONUS. They are also listed on ebay right now but I will cancel the auction if bought through here.
