Conclusion:

I’ve made three of these so far. Each one gets a little better. I’m almost there. I’ve almost convinced myself of what I already know: This is probably as good as it’ll get without spending more money on quality drivers…

Tips & Tricks:

Get the highest voltage/amperage power supply you can find.
I mount the passive radiator upside down and add weight until it sounds how I want (I’m not even sure how much weight is on it).

About the Designer:

I’m a nut.
