4" ported speaker box

It's a ported speaker enclosure for 4" speakers. I used a 2-way setup with woofer and tweeter, adding a second box and woofer to match impedance of the house woofer with the cheep car tweeters. The woofers were units I've had for a couple of decades, meaning to do this sort of thing with. These woofers are RadioShack/RCA replacement units from the Linaeum LX-4 speakers. I don't see why other 4" drivers wouldn't work but these are what I have to play with.

I've included two back covers. Each has a different connector style in mind. These are just the panel connectors I had on hand so you may need to adjust them to suit your needs.

Sort of a remix, more inspired by: https://www.thingiverse.com/thing:4750820
