I had some small Focal ones that were ok at best.
You want them small enough to wall mount easily but make sure they can go down to 80hz as this is optimum to cross over to the sub.
If you want real impact I would consider buying the speakers and sub separately.
Then you can 'go large' on the Sub. You also want to prioritise the centre speaker since the vast majority of your sound, particularly speech, comes through it.
