I recommend you keep looking. Focal builds their own drivers… you want them to match sonically. This is key for front channels… 85% of the sound in HT comes from the center channel.
Now on to the important subject. Having a stereo / HT combo. I know you didn’t ask, but here is my recommendation. Don’t do it… unless you have no choice. It screws up the audio for music and HT has different less stringent requirements. I would rather have my audio system in a small bedroom that I could control than mix it in a much bigger room. Fortunately, we have separate systems on different floors and they both sound fantastic.
