Mapman, these have nothing in common with the K2s or vintage JBLs. They're
made by a separate division with its own design priorities. Having said that
they're probably pretty good for what they cost. My recommendation is to look
for a L200 or equivalent 4300 series studio version as an entry point for the real
JBL magic. There are other fine JBL studio speakers from the 70's.
