remained in production for the next 55 years. The D130 featured a four-inch flat ribbon wire voice coil and Alnico V magnet. Two other products were the 12-inch D131 and the 8-inch D208 cone drivers. The Marquardt Corporation gave the company early manufacturing space and a modest investment. William H. Thomas, the treasurer of Marquardt Corporation, represented Marquardt on Lansing's board of directors. In 1948, Marquardt took over operation of JBL. In 1949, Marquardt was purchased by General Tire Company. The new company, not interested in the loudspeaker business, severed ties with Lansing. Lansing reincorporated as James B. Lansing and moved the newly formed company to its first private location, on 2439 Fletcher Drive, Los Angeles. A key to JBL's early development was Lansing's close business relationship with its primary supplier of Alnico V magnetic material, Robert Arnold of Arnold Engineering. Arnold saw JBL as an opportunity to sell Alnico V magnetic materials into a new market. Lansing was noted as an innovative engineer, but a poor businessman. Decker, his business partner, had died in 1939 in an airplane crash. In the late 1940s, Lansing struggled to pay invoices and ship product. Possibly as a result of deteriorating business conditions and personal issues, he committed suicide on September 4, 1949. The company then passed into the hands of Bill Thomas, JBL's vice-president. Lansing had taken out a $10,000 life insurance policy, naming the company as the beneficiary, a decision that allowed Thomas to continue the company after Lansing's death. Soon after, Thomas purchased Mrs. Lansing's one-third interest in the company and became the sole owner. Thomas is credited with revitalizing the company and spearheading a period of strong growth for the two decades following the founding of JBL. Early products included the model 375 high-frequency driver and the 075 ultra high frequency (UHF) ring-radiator driver. The ring-radiator drivers are also known as "JBL bullets" because of their distinctive shape. The 375 was a re-invention of the Western Electric 594 driver but with an Alnico V magnet and a four-inch voice coil. The 375 shared the same basic magnet structure as the D-130 woofer. JBL engineers Ed May and Bart N. Locanthi created these designs. Two products from that era, the Hartsfield and the Paragon, continue to be highly desired on the collectors' market. In 1955, the brand name JBL was introduced to resolve ongoing disputes with Altec Lansing Corporation. The
