This listing is for a single (1) vintage Altec Lansing 15" 420A Biflex woofer, removed from a 879A Santana speaker I have parted out. The woofer has been reconed at some point in its life.

 I have tested the woofer with music, a 30Hz test tone & a multi meter. The woofer sounds great with no voice coil rub. DCR = 5.8.

 The woofer is in very good working & cosmetic condition for its age. I installed a new dust cap on 3-29-24.

 Woofer will be very well packaged for safe transit.
