Vivid is a tough one because their products are so unique. Fiberglass cabinets (which matters) and custom drivers that are designed for optimal interaction. You might look at Wilson Benesch, Marten and Rockport.
How big of a speaker are you looking for? Are you looking for monitors or larger floor-standers? I produce composite cabinet speakers (fiberglass or carbon fiber) that are smallish monitors with a pretty good WAF. I don't claim to be quite in the same league as Vivid, but I think mine are pretty good. They are the Verdant Audio Nightshade and Blackthorn.
