I have a pair of JBL Lancer 99's that my mother bought new in I believe 1970, and I am having restored. When she purchased them, she had the entire audio system installed by the retailer, a very high-end audio shop. The speakers were placed with the bass speakers on top. Most photos I see of the 99's show the bass speakers on the bottom(like most other speakers are shown). Additionally, I have an old JBL brochure that we kept from the time of when the JBL's were purchased, and it shows the Lancer 99's on their side. So, is there a "correct"orientation and placement of these 99's? Or ,is it "whatever sounds best"...
