B&W CC6 as surround speaker Vertical ?

Have a niche midway along my wall currently occupied by a vertical B&W LCR3; it would also hold a CC6, but I wonder about the horizontal dispersion. The LCR3 advertizes a 40-degree horizontal dispersion in vertical mode (and works well), but I can't turn up and info on the CC6. Any advice/suggesstions will be gratefully reveived.
Thanks,
Jon
