"The Altec Duplex is arguably the most famous speaker driver ever made. It remained in continuous production from 1943 to 1998 and set the standard for critical monitoring applications. Through the 1950`s, and into the 1970`s, the 604 was used by more recording and broadcast studios than all other monitor systems combined."
