JBL L220A

Ok old timers (Like Me). Does anyone remember this pair from the late 70s? These speakers feature a 15" passive radiator, a 14" active woofer, a 5" midrange, and the a "Cat's eye" high freq driver. I really liked the sound of the JBL L65 Jubals and the L300, L200s ect. I have a chance to take a long drive to pick up a pair that is priced right and near mint in appearance. The question I'm asking before I make the trip is this, Is the sound of the L220A's along the same line as the Jubals or other JBL models of that time that I listed. If someone is familiar with the JBLs maybe they can clue me in as to whether I'm wasting my time on this model. Thanks!!!
