This listing is for a vintage SEAS H-086 1" soft dome tweeter, removed from a pair of Bang & Olufsen P30 speakers I have parted out. Please not this is the 4 ohm version. These were also sold in an 8 ohm version. 

 Tweeter was tested with music prior to removal & also with a multi meter after removal. It is in very good working & cosmetic condition for its age. DCR = 3.7.
