This listing is for a pair of Eminence made 15" woofers, removed from a pair of Allen HC-15 organ speakers I am parting out. 

 Woofers have been tested with music, a multi meter & a 30Hz test tone. Both are in excellent working condition & very good cosmetic condition for their age.

 Impedance is 8 ohms & DCR = 6.7 & 6.8.

 Mounting hole opening required is 13 7/8". 

Here are the Thiel parameters I found on Audio Karma.
