What does it mean to "tune" a box?

[QUOTE="PV Audio, post: 2150084, member: 554493"] Wrote this in a thread yesterday, hope this quicky helps: Port tuning depends on three things: port area, port length, and internal volume. There's a relationship between the three. Given the same box for each experiment, here's what happens: a. an increase in port area increases port tuning and requires either a longer port length (and conversely more Vb to compensate) or more internal volume b. an increase in port length MAY and USUALLY does give you a lower tuning, but it lowers the Vb. If your box is already too small, increasing port length is futile because the more airspace u take away, the higher the tuning will get c. an increase in internal volume will always lower port tuning no matter what the other two are doing [/QUOTE]
