Swan Diva's are ok, but to my ears the best Swan speaker ever made was the "Cygnus" in its revised form. It was built in Canada at that time with a beautiful Rosewood cabinet, top quality crossover, kevlar mid range x2 and an accutron inverted cone tweeter. Woofer fired internally through a tuned port. Built like a tank and just as heavy. I have a friend who still has a pair and drives them with mid powered tubes to pleasant listening levels in a 20' x 30'x 30' vaulted ceiling great room. If you can locate a pair audition them.
