I have a pair if KG 1.5s that I have had forever. I finally got them out of storage after seven years and I’m going to be mounting them to a wall in our new home. I bought some NOS Omnimount 75WG brackets as they are supposed to be the correct mount for that speaker, but they didn’t come with any bolts of any kind. Can anyone tell me the size and length of bolts I need to fit the threaded holes on the bottom of KG 1.5’s. I know I can take the speakers with me to the hardware store to try to find some, but thought I would check here first.
