    energizer transducer

    Hi all,

    a year ago I started a question about the relationship between the board numbers of the SE 400/408 EQ cards and the JBL speaker models. For those who donīt know, the JBL 400/408 amps allowed the installation of specific EQ cards to optimize several speaker systems. A fantastic idea for me and much better than "tuning" a system with cables or so but it seems nobody liked the idea to optimize the entire amplifier-transducer chain with passive equalization and current feedback. Perhaps a new member of this forum can help me or someone got the informations in the meantime.

    Thanks again,
