I try dynaudio d af 28

Morel HU9.1, Dynadio Pentamyd 3-100, HiVi D8.8

Anyone know where to buy Morel HU9.1 woofer? Thinking of replacing it with Dynadio 24w-100.
Maybe anyone can recommend a different repl. woofer. Heard a lot about HiVi D8.8+, but not sure if it produces high-end quality sound....
