I opened one of my Lascalas and pulled the woofer. It has a square magnet with no identification. Although the magnet looks Klipsch it is not the same as a K-33e I have. The basket looks Klipsch but is unfinished metal. The surrounds are rubber rather than doped paper cone. Numbers on cone are hard to read, P15003230 I think. They seem to have deeper bass than my Belles. Anybody know what I have?
