This was a fun and challenging build!

I ordered some cheap single board amps and power supplies from AliExpress and used a DSP so each speaker (mid/tweet/sub) has their own dedicated amp and fine tune control ability for the frequency drop-offs, gain, etc.
They sound amazing!
Wow that's really cool! Out of curiosity, why did you make the sub cabinet so tall?
I made the sub use a transmission line for porting, which you can see in the full gallery.
This gives it a really low frequency response, but takes up a lot of room.
Oh, gotcha. I don't know the first thing about building/wiring audio, I just haven't seen a sub with a cabinet that tall before! It looks great under the desk in your setup.
TIL all about transmission lines. Thanks OP!
