Vintage radio dual driver isobaric 6th order

###Sorry for the bad pics, this was a finished project which i took apart for some maintenance and upgrades###

This is more of a project than a simple 3d-print, but i hope it sparks inspiration, courage and confidence to anyone attempting something similar. For me it started more like a “What if” and kept on spiraling until it reached the dual driver isobaric 6th order bandpass thing you just clicked on. 

The drivers:

•  Dayton Audio PC83-4 (~15$)
• 40x90 speaker salvaged from a JBL Charge

The goal was to have the full range coverage that the PC83 offers with a bit more low end. 

I went through several iterations with just the PC83 and a ridiculously long folded port to try to reach 35Hz, which it did, but the driver really doesn't like to be pushed in that region; then i designed this box which uses the driver salvaged from a JBL Charge to effectively push the PC83. Now the PC83 was effectively in a sealed box (at least for the frequencies that it likes) and the JBL driver was on one side with a passive radiator (the PC83 below 80Hz is essentially that) and on the other side a cascaded port which should tune to the 35Hz.

The raspberry pi runs volumio, boots from SSD and has a DAC/AMP hat.

IF there enough interest i will write a more detailed coverage of the build, though i doubt this exact radio is so widespread.
