How to Build DIY Speakers

I'm very interested in building some DIY speakers and by day I think I just heard my wife making noise over there she's probably going to attack me in the middle of this episode.

There's a part where the real world meets things that you can't necessarily define in an algorithm so how much do you trust software when it comes to your home audio system? You're not gonna hear what they want to hear unless you go to extreme detail in modeling the room  in which case we'll be playing bottles gate see you later.
