Dave, just be sure and order the appropriate mount for your speaker, IOW weight. They are completely adjustable, they swivel, however unless your speakers have threaded female studs on the backside, you will have to drill into the back of the speaker to mount the omnimount plate. The plate takes 4 screws to secure. Some speakers have these threaded inserts, check yours out and if they do, go to Omnimount's website and look for your speaker manufacturer. Good luck!
