Ken Crane (left), founder and president of the Los Angeles-based Ken Crane’s Home Entertainment, standing with Tom Campbell, who has just joined the retail chain as a spokesperson and board member. Campbell had a similar role at Dow Stereo & Video, San Diego, which he left in the wake of Dow’s recent acquisition by Tweeter Home Entertainment. It’s all in the family, however, as Crane’s, Dow and Tweeter are all members of the Pro Buying Group.
