thanks again fellas
3 things to test #1 test the ohms between + and - terminals. Technically you should test Impedance with an AC setting.(more accurate) Most multies test in DC Impedance close enough to tell quality of speaker. An 8ohm speaker to see if reasonably alive the reading can be from mids 6's to high 7's in ohms.
#2 is tow inspect all glued edges and looked for sloppyness aka patch job. Most of the black glue should be uniform in diameter all the way around.
#3 Listening test. Depending on recone or non recone you should slowly over a month work your way up to a loud volume on a recone to break it in constantly listening for cone flutter, On a speaker thats put in the time go through all volume levels and treble and bass levels constanly checking for flutter.
I have yet to be disappointed with ebay and made some good contacts on there. My first JBL e120 was a recone from a great reconing service in Detroit. I scored 3 k120's still original jbl boxes all original and never in use from an out of bizz studio in Toronto. The coolest find with a sad twist were 3 e120's that came from a 4by12 cab used by SRV in which the cab's floor with castors came loose from his last tour ever in 89. They sound amazing and totally clean and broken in tested one by one with a Hafler SE120 SS amp and a blackface FET tubless pre(not recommended) I built in my spare time.
