Eminence beta 12CX 12" inch Woofer Speaker for Sealed or Vented Enclosures

This is a very nice Eminence 12" inch speaker for vented enclosures. This speaker has been tested and is working great. I am listing this speaker as used because I have no history of its prior use. I however see no signs of it ever being used or installed. I did test this speaker using my home stereo system and it is working fine. I will ship this speaker in its original box. The Specs. are listed below. Please feel free to ask questions.
