In case anyone was wondering, I reached out to Terry Hanley Audio to try to get more info on my speakers. He told me that his company was in charge of Aerosmith's audio for touring arenas and stadiums. He cannot guarantee that my speakers were used for these tours, but there's a good possibility. He usually ran Scalas for wide sound I believe. He used a mix of Klipsch and EV speakers for concerts. His history in the live music industry is very impressive. My speakers were made in 1980, so they missed some of his more notable concerts, but none the less, I am sure they rocked some good crowds at some amazing concerts.
