    What the Hay is this? "JBL Sound Motor?"

    https://www.ebay.com/itm/165704145150

    Can't read the model number, but the label seems authentic to me for the Los Angeles era. It's old enough to have a genuine Cannon socket on it, and what...

    Just want to say +1 on the Carpenter's Wood Glue Max. It's the best I've used.

    So you want to convert the horn crossover from a bandpass filter to a highpass filter. I'd start by shorting across the series .27uH inductor and removing the 2 3uF caps that drain the HF off and see...

    Might try some tar remover from an auto store on that magnet.

    Falls right in line with the 2 x 3" ports 5.75" long that Bass Box 6 gives.
