Difference between front and rear ports?

[billfitzmaurice]

My understanding is as stated above, but Saturday-night’s gig just popped into my mind…

outdoors under an open tent, rig at one end facing across stage.

No wall there for anything to bounce off of.

Would not a front-ported cab benefit the stage more than a rear-ported, as I’m just picturing that going off into the night?

Read the preceding posts, then look up the definition
of the word 'omnidirectional'.

Why bother placing your cab(s) facing any particular direction? Just stick them anywhere pointing in any direction and they’ll be fine, no?

Output above 200Hz is not omnidirectional. But there is no port output of any consequence above 200 Hz.
