Hi guys, i am bit of a newbie when it comes to diy speaker building so any help would be much appreciated. I am currently in the process of designing an outdoor speaker bar to hang above my bbq. The design is based off of 2 overnight sensation MTM speakers formed into a 1.4 meter long bar with a 5 inch Tangband sub in the middle. My problem is deciding whether to front or rear port the "overnight sensation MTM" speakers. I have read that there is not much audible difference between front and rear ports as base waves are "non directional" and bounce off of walls. would this be the same if the speaker is outside? considering there are no walls for the bass waves to bounce off of. I want to squeeze as much bass out of the little drivers as possible but there isnt much room for the OS MTM ports on the front so would rear porting the speaker make any difference? sorry if the question sounds a little confusing, I guess a simple way to put it is, do rear ported speakers work as well as front ported speakers when placed in an outdoor environment? Thanks guys!
You have summed up the situation correctly in my opinion.
In an outdoor environment I would recommend directing the ports towards the listeners.
If there isn't much room on the on the front then consider which port shape would best fit e.g rectangular as opposed to circular.

On further thought . . . !
At bass wavelengths the port output goes everywhere. Therefore it should sound the same when listening at a distance regardless of whether it is on the front or the back.
The presence of a rear wall would make the sound different but in the same way for a front mounted port as for rear mounted port.
To summarise, rear ported speakers will work as well as front ported speakers in an outdoor environment!

An MTM sounds pretty bad laid on it's side, ever heard one in that config? Consider reducing it to a basic 2-way or even better use coax drivers.
I'd strongly recommend against hanging anything other than food over a BBQ.
You will literally cook the drivers and electronics.
+1 on coaxials.
Also, if you're adding a subwoofer, there's no need to port the midbass unit - let the sealed box rolloff form part of the crossover.

chris661 depends on what kind of sauce you finish cooking the speakers with, no?
orange glazed tweeter anyone?

True, and the marinade beforehand makes all the difference. I'd recommend a 50-50 mix of teriyaki sauce and chilli oil, and then a little salt before it hits the grill.
