Following a recent announcement of "diminished expectations" for the near future (see <A HREF="http://www.stereophile.com/news/10194/">previous story</A>) and a shakeup of upper management---in which Consumer Group marketing honcho Tom Jacoby was put out to pasture and audio guru Floyd Toole was promoted to senior vice president of acoustic and transducer engineering---<A HREF="http://www.harman.com">Harman International Industries</A> has put the finishing touches on a new 10,000-square-foot audio laboratory. At company headquarters in Northridge, CA, north of Los Angeles, the laboratory includes a 10,000-cubic-foot anechoic chamber for testing and measuring loudspeakers, and a multichannel room with computer-controlled, hydraulically operated platforms for positioning front left, center, and right speakers (a reviewer's dream!).
