I don't want to pile on here, but just to make a minor comment. I'm not a professional designer, but a pretty serious hobbyist who has made a rather concerted effort to learn how speakers work.
Completely unlike the guitar, and even hi-fi worlds, the drivers for bass cabs are essentially PA or "pro audio" drivers. Some are marketed
for bass use, and some are also often designed for low cost. Sometimes amp makers use pretty much the same drivers, but order some custom features and have them re-labeled. But in terms of specs, performance, and how they work in typical cabs, bass and pro audio share enough commonality that a lot of DIY'ers and high end builders use exclusively pro audio drivers for bass cabs.
