Bookshelf Speaker wall mounts

[Pana440]

Looking to put some Tannoy mercury F1's on my wall either side of the sofa (limited space on the floor) Would these be sufficient and do the job ok?

I am looking to mount them up high-ish and be able to tilt them to the listening position. Help would be appreciated, thanks

I would also like to know if they will work as i need to wall mount my diamond 9s and not sure what to buy?
