Up for sale, a SINGLE Bose 901 4” driver removed from a Bose 901vi speaker. I am parting these speakers out and currently have 18 drivers available. You will receive one Bose 901vi driver with the gasket and mounting screws. This is an original BOSE driver, not a chinese replacement. The series vi drivers do not ever need to be refoamed. View my other auctions for an array of interesting items at great prices. Please see the attached pictures, please note that this listing is for one single driver and that the last picture is of rhe actual speakers that are being parted out. The driver that you will receive may not be the initial one pictured, but it will be one of the ones that havent yet been removed yet in the last picture. Please see the attached video for a demonstration of the speakers, which are in good working order and sounding great. Please ask for additional pictures or videos if needed. I do NOT accept returns on any items. The vintage stereo gear that I sell IS vintage, meaning that it is 30, 40, or even 50+ years old. With that being said, I can not offer any warranties on it. Although I have never had any issues with anything I’ve sold, I want to note that. If I have a piece of gear that is questionable in any way, i will either list it as “Parts or Repair” or I will note the issues that I have found. Thank you very much for your business.
