Hey Cosmic,
I’ve kind of been looking at your threads. I’m going to give you advice I’m sure you won’t take.
Rather than try and treat your speakers like some sort of board game, you need to invest in your tactile and auditory learning. In other words, stop trying to theorize and grab some parts and learn what you are talking about in your gut.
Given your interests in active crossovers, grab a miniDSP and a tweeter and woofer from somewhere and try making a whole speaker out of it.
Maybe buy the parts for a cheap 2 way kit, but not the crossover.
I promise you, that if you spend a week doing this your questions here or at DIYaudio will be entirely different and
your investment in yourself will be completely worth it.
Best,
E
