This listing is for a single (1) gray rubber trim ring, used on the 6.5" midrange speaker on the Bowers & Wilkins DM640 & DM640i. It may have been used on other models as well, but I am not sure.

 I have 2 trim rings available at the start of the listing. IF YOU WANT BOTH, ENTER QTY. 2 AT CHECKOUT.

 Both are in very good condition for their age. O.D. is 6 3/4".

THE MIDRANGE SPEAKER IN THE PICTURE IS NOT INCLUDED.
