This listing is for a single 10" Advent woofer, removed from a single New Large Advent I have parted out. These were also used in the 4002, 5002, 5012, Advent/1 & possibly some other models. These are the oversize 10" woofers that measure 11 7/16" across & 12 1/2" ear to ear on the diagonal. 
 The woofer was reconed by a local Houston speaker repair shop some years ago & the surround was rotten, so I installed a new one. I installed the surround inverted in order to fit the cone properly.
 Woofer haS been tested with a 30Hz test tone, music a multi meter. It is in very good working condition. DCR = 4.8.
