    Here are the notes for the cabinets.
    I have pics (7mp), but don't have a clue as to how to post them
    Perhaps some kind soul will step up?
    Please feel free to ask for any further info,
    Don



    JBL 4645C cabinet dimensions

    25 ½” W x 39” H x 17 ½” D

    Front and rear baffle are made from 1” MDF

    Top, bottom and sides are made from Ύ” MDF

    Internal brace is Ύ” MDF 37 ½” H x 24”W with cutouts and centered front to back

    The cutouts are 4” x 17 Ό” and 25” x 17 ½”

    This leaves a 3 5/16” thick border around the inside of the box and 2” behind the driver

    1” fiberglass behind the driver, on the bottom and lower sides

    Above the driver area there is nothing except paint behind the port opening

    Front to back stiffener at the top center of the driver cutout is 5 Ό” x 16”

    Port ID is 7 1/4”, OD is 7 ½”, tube is 1/8” thick paperboard material

    Port length is 12 ½” from front of baffle to end of tube

    Tube is rabbeted into baffle 5/8” overall length of paper tube is 12 1/8”

    The front and rear baffle boards are set in ½” from the edge of the side boards.




    Disclaimer: I know that the spec sheet for these has different dimensions for the box.
    BS, I say! I have two off these that were ordered at different times and both share the measurements shown.

    There is a limit due to bandwidth and these pics are huge. I don't know how to resize them.

    I can E-mail them to you if you like.

    They need to be posted to the archive to keep them for future reference.

    Don:

    Your photo editor program will have a "Resize" function, most likely. I edit down to 480 x 600 for posting here, after saving the resized pics as separate files so as to retain the originals as well.

    I guess we need just a few more dimensions -

    Distance of port from edge
    Distance of driver from edge
    Distance of input terminal from edge

    Thanks!
