Welcome to the Community! Thank you for reaching out today. I will do everything I can to help.
Currently we no longer stock the 901 series VI speakers. But we do have many alternatives on our website.
We can also provide services for the 901 speakers should you want to keep the speakers.
If you click Here and select your region then scroll to the bottom and select "Contact us" where you can find the contact details to speak with out Technical support team
should you want to have a service on your 901 speakers.
Or as I mentioned earlier you can visit the Bose website to browse our range of speakers.
I hope this has helped you today! Please do enjoy the rest of your day!
