    Great suggestion - I don't use that enough (sorry, Don...!! :o ).

    I've redone them all - let me know if that works...

    1977 JBL Transducer - Enclosure Porting Information

    For reference -

    There are a few changes from the 1975 chart. Plus the 1977 chart includes the tunings for the 3.0, 5.0 and 8.0 cubic foot enclosures as described in the Enclosure Construction Kit which Bo has posted in this thread. One should notice the discrepencies.

    Thumbs up I am ALL puckered up and Having Fun!!

    Hey, Giskard...

    Combining these fb charts with the plethora of JBL discursive literature you posted over Labor Day provides a powerful - shall we say "enabling" ? - reference for better and precision JBL cabinet building.

    Wonderful, wonderful stuff.
