Center channel with in walls

What do people liked for a great center without considering the right and left speakers? I have about 10" h while depth and width are no problem. I realize that matching R and L speakers is best but I'm more interested in the center.Budget is around 500-700.
I had similar constraints. Have been using the Vienna Waltz for my CC, it's right at the high end of your budget, just under 8 inches tall if used horizontally .
Very musical. I have Vandersteen 2Cs for my mains.
thanks Saeyedoc. I really like the Vandersteens.
I use thiel powerpoints for my center and surrounds, very happy but they may be over your budget.
