Gutted the JBL L150's today. Pulled the crossovers and L pads. Packing the L pad holes with plastic wood to plug them, sand, paint.
Knocked out the original jack plate on the back and will fab a new one to hold 3 jacks, one for each driver.
I've had the resonators, woofers, and mid range out before, and they tested good and still test good. The prior owner sent them out for new surrounds and they still look very good.
Pulled the tweeters for the first time. Fook!
Crap soldering on one and a shifted magnet on the other. The shifted magnet one is reading 12 ohms.
Going to pull it apart and see if I can fix it.
These have the soft dome and look good.
Never seen a shifted magnet before, but there's a long thread on AK about fixing them.
Appears I can test these simply at different frequencies with the DER EE LCR Meter or a frequency generator.
