Hi All !! I've recently ventured into the world of Polk Audio and purchased the Blackstone TL 150 Series. I need help with locating quality wall speaker mounts for the satellite speakers. I bought a pair from Amazon but the threaded hole is a 1/4" -20 but it's recessed so far into speaker that a standard fitting won't reach. Has anyone else had this issue ? Ideas - Thoughts - Helllllllllp !!!! Sorry if this question has already been asked / answered. Thanks Everybody !!
