Thinking inside the box
To anyone with knowledge, be it professional or novice, but only serious answers. Just as the title implies I'm thinking inside the box. I am a huge advocate of car audio, I'm 40 years old, matured in the mid 90's. Been into car audio for a long time as a hobbyist, and for the last 3 years all the technical stuff from T/S parameters to 8th order bandpass enclosures are now making a lot of sense to me. So with that said, here is my question. How would a ported enclosure or sealed for that matter, behave if there where smaller chambers inside the enclosure (we will say 2 more). So picture this inside your head, take a enclosure sealed or ported, and on the back side of the enclosure you cut out a port to what ever size is relevant to the enclosure, now you build another enclosure perpendicular to that side of the original enclosure, and then repeat that process one more time. Each additional chamber would be somewhat smaller than the next. This is my first time posting, I hope this attachment illustrates it better. My goal is to produce a enclosure that would tune itself according the lowest frequencies present. The open port would be tuned to a given freq, as the second port unloads because of its tuning, that would make the first port tuning freq change. Its very hard to contemplate what happens after that. Someone with really good knowledge please reply to what is really going on in such a setup.
