Port up? Port down?

When building a wall, is there a correct placement for the port? Should I put it up? Should I put it down? Advantages/Disadvantages?

You're going to have seats and a console right? Why would you put it on the bottom?

Yes I will, but they won't be right up next to the port - maybe 8-10" away. I've read in different threads and seen in a few builds a port on bottom for loading purposes. I've never done something this big, so I figure better to ask and get opinions than to guess and have something that potentially could have sounded better.

One is better for SPL dash scores, one is better for daily demo's. I forget which is which though, sorry

Hands down demos. I'd like to have a decent score on the meter, but demos are more for me.

It's either going straight to your ass or blowing your hair like a blow dryer. If I were to guess, the top would be for SPL dash score and bottom would be for daily. 50/50 chance lol.

I think that's what it was actually, because of port distance to your head. I'll double check though

That sounds right now that I hear it. Just a rough guess, what do you think the meter loss will be with the port down low? 1-2db?

I just read that port on top was bad for sealed numbers. Not sure if that's accurate, but that's all I found

No problem, hopefully more people will weigh in too

Why couldn't you spread the subs a few inches and do a vertical port in the center? That's how we did them way back... just asking?? Maybe things have changed, but that always got us the best of both worlds .... At least we thought it did back in the early 90's ...lol...
