Speakers that fit with no mod to factory housings, $30 a pair, and here’s how I did it (post now works!) Options

[Garland]

I wanted to set of speakers in the factory pods, without hacking anything up, hoping for a little better sound than the 50-year-old paper, torn speakers.



Omega 4 x 6 dual cone BU-46.7 my local speaker store says you can still order them, if they’re out of stock.



They look good except for the bright gold medal that will be seen through the grill



Also, they ride too high in the housing due to not clearing the factory mounts



I marked, the speaker where they need to be trimmed, and with some help from the clippers, done.



Now they clear the posts, and Mount flush.



Here’s the view from the front side, that doesn’t look that great



So after cleaning the metal well, so paint will adhere.

Here are 2D CAD (DXF) files for the laser cutting. Of course, they are custom for the JBL's. The main parts are in 3mm (1/8") MDF, the reinforcements which I glued on the back are in 4mm, they provide the bearing surface for the washers using the the original screw holes. You could also do them in 3mm - just might need an extra washer when installing.

3D print (STL, STEP) files to follow when I get a moment.

OK, here are the 3D files. Two versions, a one piece, which due to the part configuration, your printer will need to have support material and there may be some cleanup; and a two piece which can be printed flat on the printer bed (no support required) and then glued together (superglue, solvent, etc.). In the .zip are ready-to-print .stl's as well as STEP files if you have a 3D CAD system and want to modify them. I only put in one side, the other side should be mirror-imaged, which all CAD/Printer softwares can do.
