With a little work, I can get most of the JBL consumer stuff from most of these on line vendors. Apple and Best Buy only have multimedia stuff.
OTOH, there are eight authorized dealers here in greater Los Angeles, six of which are Frys. Since Frys basically carries only three models near the bottom of JBL's offerings, it's hardly a benefit.
The other two, it's anybody's guess what can actually be purchased there. One seems to focus on HTIB and the other doesn't actually stock JBL at all though you can order it.
