I recently acquired these JBL's and am searching for any information about them. The cabs are 38X26X16 . Their are 2 drivers per cabinet and are 16ohm , a D130 the dust cover looks silver, and an 075 HF . The crossover has a switch to change from 16 to 32 ohms. I appreciate any info, there are no labels but are beautiful with some nicks and dings. thanks in advance.
