Klipsch and Polk are popular and distributed widely thru brick and mortar stores....the internet has another set of sources but without "auditioning" but as your room is a large component of resulting audio, the store environment/setup may not reveal everything you like/dislike. What kinda budget for the speakers overall? Near future? I'd replace them all personally....eventually.....older speakers can be put to use to surrounds, old surrounds to kids/workshops, all sorts of useful things.
