Speaker bracket help

[Aizletree]

I have a Sony hifi like this one but from about 5 years ago. Same size speakers as far as I can tell.

Looking to mount them up high in my bedroom in corners
Are speaker brackets universal?
good brands? Or get Sony if they make them?

How about these:

Or if they are reasonably light, something like this:

Both require you to screw the bracket to the speaker - I would say this is hugely preferable to the type that grip the top and bottom of the speaker which are bloody ugly IMHO.

Thanks miniman, I'll need the larger ones.
