Hi there, this is my first post. I have an ear candy 212 bass cab I bought on craigslist 8 or so years ago. After a bit of research on this great site, I discovered that 1. I’m glad I didn’t order one of these new 2. It wasn’t designed very well. My question is has anyone put different speakers in one of these cabs, redid the ports and had good results? Or are there speakers that would work in a 3.17 c.f. box? It currently has 4- 2” ports 4” in length. Thanks
