Devore didelity Gibbon7.1 its center speaker?

Hi like to know if someone try it gibbon 7.1 has a center channel or bookshelf speaker is it a classic center speaker ?
Because the elements there is not look like center speaker even if they write it and another importent thing. Is it worth the money of 1500? For center speaker even if i use the devore fidelity nines as a front ?
Or i can go on center speaker coast 600-800dolars and get better resault?
