I'm pretty new to this, I've tried searching google and this forum, but can't seem to get an answer. I've been messing with a couple diff programs to help me build a ported box. I've noticed that if you have a real small port, the tuning goes much lower. Since (it seems) most boxes are shooting to be tuned in high 20's, low 30's, why would someone opt for let's say a 4" aero port vs a 2" ? As the 2" seems much more manageable (for getting lower tuning frequency) and shorter rather than doing a 4" which would require a much longer port, so what is the benefit of using a bigger diameter port?
Also, why would someone make a box with multiple ports rather than just one, as that seems to dramatically increase the tuning frequency? What's the benefit of multiple ports?
Sorry if this is common knowledge, but I really gave it an honest shot and couldn't find any answers.
