Stumbled here looking for diy speaker plans.

Looks like I found the right place.. I have had a few amazing audio experiences in my life and have wanted my own system ever since.
Im pretty crafty, have a bit of experience in finish carpentry, and light residential electrical.
I want face melting bass,

I have a few friends who are in bands and dj and they are really excited to see what some tuba 60's can do. I also know a promoter who is looking for sound systems a few times a month so there is a possibility that this could become a profitable hobby.
TBH I dont know much about sound systems, any good reads that you recommend post them up or pm me. My friends can show me the ropes IRL, but I like to read up also.
Thanks in advance.
