I use Revel 226Be for LR and a C205 in the centre in a room that is exactly that size. Like you, I use the room for TV and audio. TV is 65". The 226Be are fantastic. I would prefer the C205 to go a little deeper, but have no issues with speech clarity or volume in my smallish room. The larger Revel centres aren't available here and frankly would be too big ! Hope this helps.
