Wall mounting Klipsch ks-525... which mount?

The manual says that it uses Omnimount 20.0 but the online pictures of that mount show a single bolt, not the 2 bolt vertical pattern that I see on the back of the speaker. Plus, that speaker is at the 20lb limit...

I checked the Omnimount 30.0 but it looks like a 4 hole design...

Any help?



Thanks!

No dealers or people with these around to chime in?
