Why in the world did he mount the Crossover on the back of the passive radiator? I realize that I'm a complete newb when it comes to speaker building, but that seems so weird. There really wasn't a better place for him to put it?
Other then that it is cool to see small build, wonder if he will design a small subwoofer to pair with it.
I just got my C-Notes delivered so I've got a new project to start pretty quick here
