Oh my, these responses are encourageing. Seems my apprehensions are shifting more towards potential
amplification rather than driver failures.
Equally encourageing is how no one seems to think twice about how often or how hard they drive their loudspeakers.
After all, it would be quite a shame to be in possesion of a pair(s) of classic, vintage JBL`s only to have them on static display.
Not that I listen to excessive volumes, being 48 years old and living in a condo, most of my listening for the past 20 or so years has shifted to the Jazz genre but I do, on occasion pull out some Metallica or Boston and head for the volume-up button
Perhaps a few more replies will be enough to push me over the edge!
