The listing is for one single woofer. Please ask if you need any other used B&W genuine parts. I might get them for you. This unit is used in all B&W Zeppelin 1st generation speakers. Please check that it’s compatible with your speaker before ordering as there are some variations. The woofer is in perfect condition and sounds great. Please ask if you want to see anything in details. I will try to make more close-up photos upon request. MS297
