In 1996, Altec Lansing Technologies Multimedia established an R&D center in Kfar Saba, Israel. The center, known as ALST Technical Excellence Center, cooperate with STMicroelectronics (ALST = Altec Lansing + STMicro) and focused on advanced multimedia technologies such as USB audio, surround sound and wireless audio as well as on handheld video. The center was closed in 2001 and the development activities moved to the Milford headquarters. In May 2000, Altec Lansing's Professional division was closed by Telex and the Altec Lansing was later sold to Sparkomatic and renamed Altec Lansing Technologies. The Altec Lansing Professional line was relaunched in April 2002 by Altec Lansing Technologies using a few former executives and sound engineers of the old Oklahoma City-based Altec Lansing Corporation, bringing Altec's professional and consumer products under the same roof for the first time since 1986. The company later dropped the professional audio products and Altec Lansing Professional's Oklahoma City offices were closed in late 2006 and all remaining activities relocated to the headquarters in Milford, Pennsylvania.
